15:39.13 | gn00bie | ndim: I agree, it is a sad day |
15:55.45 | Manu | gn00bie: let's wait, it's soon to talk about it. :) |
15:56.08 | Manu | both Java and MySQL are open source now |
15:57.17 | ndim | gn00bie: BTW: http://farm4.static.flickr.com/3570/3445680296_822b1b032e.jpg looks interesting. Front left wheel, from the inside and front. |
15:57.24 | ndim | No wishbones or anything. |
15:59.50 | gn00bie | ndim: do you have more pictures of this thing from a couple of different angles? |
16:00.05 | ndim | gn00bie: Not yet. |
16:00.27 | ndim | gn00bie: To be soled in september, but they are presenting it on the fair next weekend. |
16:01.17 | ndim | Trice will be the third of the "mass market" full suspension trikes, and are probably trying to keep some people from buying now from their competitors. |
16:01.23 | gn00bie | it looks like a clever variant of a basic 4 bar linkage |
16:01.57 | ndim | "clever" as in "too clever for their own good", or "clever" as in "you want to buy that one"? |
16:02.25 | gn00bie | clever as in "I think it will work" |
16:02.41 | ndim | Cool! |
16:02.53 | ndim | Now, where was that winning lottery ticket... |
16:03.00 | gn00bie | the articulation is going to be less than that of a full on suspension |
16:03.51 | ndim | That's for sure. Not suitable for serious off-road triking. But on real world roads, it should be brilliant. |
16:04.04 | gn00bie | the big black chunks look like cast aluminium |
16:04.12 | gn00bie | so someone is paying attention to weight |
16:05.01 | gn00bie | most cars provide you with +-4 inch of suspension travel before you hit bump stops |
16:05.19 | gn00bie | this design should be able to get you around half the travel |
16:05.44 | ndim | 725 grams total extra weight for the front suspension, |
16:05.47 | gn00bie | maybe a little more depending on the exact design intent of that green spring element (likely elastomeric) |
16:06.10 | ndim | Definitely elastomeric. |
16:07.45 | ndim | That's what I like about Trice. No air pressure suspension elements which can lose air. |
16:07.52 | ndim | No oil dampeners which can lose oil. |
16:08.17 | gn00bie | I have worked on a very similar concept for actively deployed running boards for SUVs |
16:08.40 | gn00bie | you only need running boards when the doors are open, otherwise they are just aerodynamic parastic losses |
16:11.13 | CBG` | Hey, do you guys mind speaking English?! :P |

16:27.39 | ndim | gn00bie: BTW, I remember numbers like 30mm or 40mm suspension travel for that thing. The wishbone/air-spring/oil-dampener competition has 60 or 85mm, respectively. |
16:27.42 | ndim | ~coffee kierra |
16:27.43 | purl | ACTION steals some of Admirarc1's special coffee and gives it to kierra on a silver platter. |
16:28.37 | kierra | warming up, CBG` |
16:28.51 | kierra | spring is here |
16:28.56 | kierra | ty ndim |
16:43.16 | CBG` | kierra: What I really meant was "How are you?" :) |
16:43.30 | CBG` | But yeah, warmer here too now. |
17:04.08 | gn00bie | ndim: 30 to 40 mm travel should allow you absorb any road imperfections |
17:04.21 | gn00bie | potholes, sleeping policemen are a different story though |
17:11.59 | gn00bie | ndim: if I were designing a trike, I would go for a two level suspension |
17:12.09 | ndim | gn00bie: If they have been sleeping for long enough, they'll have been flattened sufficiently. |
17:12.18 | ndim | Two level? |
17:12.21 | gn00bie | articulation between the wheels and the frame |
17:12.33 | gn00bie | and then another articulation between the seat and the frame |
17:12.42 | ndim | Large diameter tyres, and... ah. |
17:12.49 | ndim | Mesh seat. |
17:12.57 | gn00bie | or something like that, yes |
17:13.06 | ndim | http://www.ice.hpv.co.uk/images/trikes/q/images/q_2008_b.jpg |
17:13.40 | ndim | The red part is steel BTW... for some elasticity. |
17:14.09 | ndim | Front boom, and rear fork are aliminium. |
17:15.56 | ndim | "heat treated aerospace Aluminium" |
17:16.07 | ndim | Whatever that means :-) |
17:16.31 | gn00bie | well, aluminum needs to be tempered after it is cast |
17:16.45 | gn00bie | there are various temper levels, the engineer is suppoused to pick one |
17:17.13 | gn00bie | if they are claiming aerospace grade, it is either a 6xxx alloy or a 7xxx alloy with a T5 to a T6 temper |
17:17.43 | ndim | http://www.ice.hpv.co.uk/trikes/features.htm#frame |
17:17.53 | gn00bie | cast or wrought, whatever they are doing |
17:19.46 | ndim | They don't say. |
17:19.58 | gn00bie | the boom looks wrought |
17:20.15 | ndim | The boom looks like some pieces of tubing welded together. |
17:20.24 | ndim | There's some russians who build trikes from mainly titanium. |
17:20.27 | gn00bie | at any rate, these aluminum grades exceed cheap steels when it comes to tensile yield strength |
17:20.42 | ndim | Scrap "Alfa" submarines or something :) |
17:20.50 | gn00bie | cost there days is $5isk/kg as compared to $1.5ish for cheap steel |
17:21.28 | gn00bie | russians are crazy ;) |
17:22.07 | ndim | I guess the main point of steel is to have a range of loads which can be handled by elasticity effects without aging/fatiguing the metal. |
17:22.42 | ndim | gn00bie: Yupp. The Russians even offer all wheel drive trikes. :) |
17:24.19 | gn00bie | yeah, aluminum does not like overload |
17:24.37 | gn00bie | next thing you know russians will be offering nuclear powered trikes |
17:25.12 | gn00bie | the grades of steel used for the half shafts in a car for example, can give you over a million cycles at 850 MPa |
17:25.34 | gn00bie | most grades of aluminum will rupture at 450 MPa or much less in a single cycle |
17:25.55 | gn00bie | the half shafts in your car can withstand one time overload of as much as 1.8 to 2 GPa |
17:29.54 | ndim | Which occur when? |
17:30.08 | gn00bie | when you get air :) |
17:30.19 | ndim | I am lost. |
17:30.21 | ndim | :) |
17:30.37 | ndim | Air as in flying? |
17:30.51 | gn00bie | scenario - you do a ski jump maneuver, all 4 wheels off the ground and the vehicle comes crashing down afterwards |
17:30.58 | ndim | Why should that affect the half shafts? Isn't that supposed to be handled by the suspension? |
17:31.12 | gn00bie | your wheels are spinning at a million rpm, and suddenly they encounter road instead of air |
17:31.24 | gn00bie | that sends huge torque spikes up through the driveline |
17:31.52 | ndim | Gna. Right. Like any aircraft landing... but those do not have driven wheels. |
17:32.20 | ndim | Does not sound like something you need to keep in mind for most real life situations, though. |
17:32.42 | gn00bie | other scenario is when traction control kicks and very quickly stops wheels that were spinning like crazy, that is also not good for half shafts |
17:32.58 | gn00bie | automotive drivelines are designed for the 99th percentile customer |
17:33.09 | gn00bie | which means that 99% of the customers have more driveline than they need |
17:33.48 | gn00bie | and well, there is a whole gory theory behind shaft design for endurance vs. shaft design for fatigue, I got all day if you want to listen |
17:34.03 | ndim | Hmm. With the traction control kicking in... I'd be more concerned about the gearing and bearings in the diff. |
17:34.21 | gn00bie | mildly sprained my ankle because of a weekend of playing cricket, so sitting at home today |
17:34.26 | ndim | Oh. |
17:34.58 | ndim | sends gn00bie some magical herbs for the ankle. |
17:35.11 | gn00bie | typical TCS systems cycle brake pressure in the 8-20 Hz range |
17:35.26 | gn00bie | unfortunately, most half shafts have a resonant frequency somewhere in there |
17:35.32 | ndim | GNA. |
17:35.47 | gn00bie | resonance = large amount of energy, i.e. very high stresses |
17:36.01 | ndim | That much is self evicent. |
17:36.05 | ndim | evident. |
17:36.11 | gn00bie | where is CBG` ? :P |
17:36.51 | ndim | thanks http://www.iypt.org/ for his basics in technical and scientific English |
17:36.55 | gn00bie | in this country though, steel metallurgists are an endangered species |
17:37.18 | gn00bie | this country is losing all the manufacturing know how at a worrisome speed |
17:39.28 | gn00bie | so even though limited slip diffs add some mass to the driveline, brake based TCS systems end up adding a lot of weight |
17:40.14 | gn00bie | I have never sat down and done the calcs, but my speculation is that adding limited slip diff and doing away with TCS would actually save weight, and hence fuel |
17:41.39 | ndim | Hmm. TCS being just for avoiding too much wheelspin when you put the 600hp to the ground from a standstill, or TCS also avoiding spinning in evasion maneuvers? |
17:41.44 | CBG` | gn00bie? |
17:42.00 | gn00bie | CBG`: you trade unionist hedge trimmer and traffic warden! |
17:42.15 | gn00bie | TCS for avoiding wheelspin |
17:42.40 | CBG` | :( |
17:42.53 | gn00bie | TCS for avoiding massive understeer or sever oversteer does not cycle the brakes at high frequencies, so that is acceptable |
17:43.14 | gn00bie | CBG`: you are suppoused to insult me back! |
17:43.21 | gn00bie | not :( |
17:44.07 | gn00bie | ok, just a quick trip to the sandwich shop around the corner |

21:54.52 | gn00bie | well, let us see what kierra says about your declaring kids |
21:54.55 | gn00bie | "a hassle" |
21:54.59 | gn00bie | kierra: ping |
21:55.56 | catay | yeah, he used it in a sentence to a UK customer but spelled it wrong |
21:56.00 | catay | he said 'assle' |
21:56.12 | catay | and from the context of the sentence you could interpret it differently :P |
21:56.20 | ndim | lol |
21:56.23 | catay | which the customer did and he was shocked |
21:56.25 | catay | heh |
21:56.36 | gn00bie | Britishers do get shocked easily |
21:56.50 | catay | so we bought him a a t-shirt with in big letters on the back |
21:56.59 | gn00bie | take our resident Britisher CBG` for example (there is also Admirarc1 - but he never says anything) |
21:56.59 | catay | 'NGA biggest (h)assle' |
21:57.11 | catay | NGA = my company initials :p |
21:57.16 | gn00bie | :P |
21:57.22 | catay | heh |
21:57.33 | gn00bie | so customer was asking for something and the customer was declared a big assle? |
21:57.41 | gn00bie | #define customer big_assle |
21:57.48 | gn00bie | I can see how that would lead to a problem |
21:57.54 | catay | well, .. customers can be weird |
21:58.01 | gn00bie | it is their god given right |
21:58.16 | catay | and as the vendor you always have to play nice , no matter what |
21:58.27 | gn00bie | you have never lived till you have pulled a lot of your hair out because a customer |
21:58.37 | catay | luckily i'm not much in direct contact with customers :) |
21:58.53 | gn00bie | this one time there was a big engineering review meeting for a transmission, 15 people - 5 from customer, 10 from my company |
21:59.21 | gn00bie | we were going over the list of issues that needed to be solved, and at that point in time, I was representing my department |
21:59.25 | CBG` | Ah! Damn you shocked me... |
21:59.43 | gn00bie | after about 30 minutes of - yes we will do it, yes we can do it, no the timing is not entirely unreasonable for component a |
21:59.52 | gn00bie | followed by yes we will do it, yes we can do it, no the timing is not entirely unreasonable for component b |
21:59.58 | gn00bie | and so on and so forth |
22:00.25 | gn00bie | and so Director of Vehicle engineering from customer says - I hope we are not overloading you, it is a lot of work |
22:00.41 | gn00bie | I say - Sir, you are the customer, if you want a lap dance, I will give you one |
22:00.50 | catay | lol |
22:01.03 | gn00bie | that line was in my end of year performance review - needs improvement on people skills |
22:01.13 | catay | hehe |
22:01.32 | gn00bie | our VP of engineering one time in the hall - Hello, how are you? |
22:01.37 | gn00bie | me - tall, dark, and handsome |
22:01.45 | gn00bie | VP of engineering - ???? |
22:01.51 | gn00bie | he still remembers that one |
22:02.04 | catay | yeah, i would too if i was a VP :P |
22:02.25 | gn00bie | sadly, that is the only thing he remembers about me (250 engineers work for him) |
22:02.33 | gn00bie | I am Mr Tall and Dark to him |
22:02.52 | gn00bie | because of course, my followup line had to come after the ???? (2 out of 3 is not bad) |
22:03.13 | gn00bie | catay: you are such a amateur when it comes to surprise and delight :P |
22:03.37 | catay | I am ? :P |
22:03.39 | catay | why? |
22:04.40 | gn00bie | have you ever offered a customer a lap dance? |
22:04.47 | catay | no |
22:04.53 | catay | what if he says yes? |
22:05.17 | catay | gotcha there :p |
22:05.20 | gn00bie | have you ever told the boss of your boss that you are tall, dark, and handsome (though in your case it is only 1/3 - pretty bad)? |
22:05.36 | catay | hehe |
22:05.40 | gn00bie | well, if he says yes, then you just have to stand and deliver (shake that moneymaker) |
22:05.47 | gn00bie | or the devil, he may take ya :P |
22:05.54 | catay | just saying , i'm tall, doesn't make much sense :p |
22:06.07 | gn00bie | you are tall and bald, now that makes sense :p |

22:08.27 | catay | wel, it's not yet in production, so i can still play with it |
22:09.20 | gn00bie | hopefully intel releases their Core i7 in 4 socket soon |
22:09.30 | gn00bie | so far it has only seen a 2 socket version release |
