Matlab seem to be good option for me, however, it's quite difficulte to contrust the block diagram in simulink. I am the only person working on suspension in my team. I will try others u suggested, anyway, thx a lot

i just visted their website, but there is nothing i can use as simulator in their website, anyway thx a lot

I use Optimum K. It's great!

Optimum G do a discount for FSAE teams.

Well it's not free software, you need a license to be able to download and install it.

But do talk to dynasim, see if you cant get a discount or a short time license sponsored.

It's as if you've asked. I'm making a kitcar, what's the best engine. And you've got one guy replying "engine from the Bugatti Veyron!" and some other people replying "Ford Zetec 1.6".

Since you are the only guy and you have not quoted a budget and you probably need to get a result that is usable on the car I recommend that you would stay clear of programs with limited license. It's just my opinion but to me it's like buying a second hand car with 150 000 miles on the clock. I'm one for having things for a long time and not be worrying about finishing the design 2 days before the licence runs out...

I would take the advice of those who have quoted you:

1) Excel: remarkably easy as long as you are ok with linear algebra and investigating your suspension in 2d. Forget what people say about the 3d world. You need to get a grasp of 2d before understanding more complex things anyway. You can do approximate force based roll-centres in 2d for example.

2) OptimumK. Specifically for students and FSAE so probably the easiest to use and get support from. Not that expensive for a team to buy and you can prolly run it forever. OptimumG has close links with FSAE.

3) Susprog. Many recommend it and the author has made quite a clever program. I would try this.

As for the rest

4) Lotus Shark I think only runs on one comp so it will be yours and that's it. Also dunno if licence runs for one year. It is VERY intuitive and gets you results quick though! Email Lotus Engineering and ask your tutor to give you a reference.
5) Adams. Get your Uni to fund this but they make ask you for some results! Since it's not that cheap.
6) Dymola a bit like a nicer looking and quite upgradable Simulink but requires some training I would say.

WOW! thx for ur advices, it's very useful for me, actually i am using excel to do simulation, but i want something to show in 3-D, i think i can work it out with ur advices

cheers
