Far out that FSAE car from the K&C measurements is quite a mess.
Hi Vivek,
As far as I know MSC don't support student versions of Adams. You can try asking a question in the university version of the msc-forums.
Do you have any documentation on the FEM model...
That assembly is a steel tube which houses the potentiometer (blue cylinder) and 2 bearings for the vertical spindle. The tube is threaded on the outside surface for mounting to the vehicle.
I...
A caster wheel ('roulette pivotante' in french accoring to leo.org) in its simplest form is a shopping trolley wheel. The wheel will, in steady state, point along the velocity vector of the mounting...
Claude,
Out of interest, how many of the teams using a slip angle sensor have built it themselves?
Has anybody else figured out that a caster wheel will do the trick?
"Bushing" is MBS-speak for a 6 d.o.f. joint. It can be as rigid or a flexible as you want in any direction. If you are just calculating FEA loads then setting the rotational stiffness' to zero and...
I don't know so much about the competition but I use that same software for simulator/simulation work.
From what I understand the manoeuvres are all closed loop using the virtual driver included...
Erik - such a virtual FSAE thing already exists: VI-Grade Virtual Formula
This was more or less my line of thinking

It's not an additional force over the load transfer but a component of it. It's the part of the load transfer coming fron the roll center and anti-pitch effects of the suspension.
There is a...
Apart from that there's a note in drawing about the depth of the circlip grooves you should take into account.
The shaft broke because the design is wrong, not because the material is wrong.

Not if it's done before the test and as a result you didn't waste the whole morning chasing an understeer problem.
Simulation's strength, if used correctly, is that it lets you test more...
Why? If the car is on fire you just step out of it. Like this guy did.
The UI of any serious engineering tool is always a disaster - get used to it. You can't assume industrial tools will work like your iPod.
I've noticed a pretty strong inversely proportional...
Most of the suspension/vehicle software (I have used) is geared for analysis rather than design.
One of the most valuable things I ever did was to invest the time in an excel model which...
I'd tend to agree with Claude that Adams is bordering on overkill/too complicated for FSAE stuff unless you have done a training course. It's strength is it's flexibility but from a user point of...
The problem is either:
Your calculation is wrong
Your Adams model is wrong
They are both wrong.
But unless you explain the calculation and exactly what simulation you ran how can anyone help?
The (incorrect) use of the "mass centroid axis" in vehicle dynamics was popularised in Carroll Smith's "Tune To Win" which was subsequently used as a bible for many vehicle engineers so the idea...
Yea, I think you only need to justify your solution if it doesn't appear in Tune to Win. Just ask UWA.
The same could be said about any sports car though.
Anyway, why are we talking about vehicles with a non zero track width in this thread??
I didn't get offended, I demand a refund.
Costs a lot more than a quarter these days but noone stopped me a few years ago from doing a lap with a long wheelbase Ford Transit with 2 couches in the back for extra downforce.
It's a public...
I don't think the issue is just the fact that off-the-shelf parts are used.
The issue is when they are used like a backyard mechanic. I.e. slapped on without understanding a single thing about the...
I'd happily accept a kit car if the team was able to show that they used the extra time won (from not making and remaking parts) to actually design the vehicle layout properly or even carry out a...
