Multi-body Dynamics Software to Analyze Suspension Systems

[shoulddt65s]

Hello all,
I am creating a simulation program to model the suspension of a racing vehicle. The front suspension is a common double wishbone without a sway bar, but the rear suspension is unique to this form of racing only. Therefore, readily available programs cannot model the suspension system I need. I have created an Excel based tool that solves the static system. For the dynamic response of the system I was looking for a multi-body dynamics software that I could import the suspension dimensions and joint information into in order to analyze the dynamic response of the system. I just need a software to help model the motion of the suspension links given a set of input forces and accelerations. I don't need the program to have a tire model or account for any compliances. Also, the program does not need to have a graphical or CAD interface. I just need to import the vehicle parameters and a set of loads/accels, and have the program output a list of results.

I have seen a number of free multi-body dynamics codes/software that may be capable of accomplishing my task, but I was wondering if anyone has any recommendations or advice. I would also be willing to purchase a software package if it was capable of accomplishing my tasks and wasn't ungodly expensive.

Thanks,
Dustin

Freecad should be able to do that. Autodesk used to sell an app that would probably do that.

Sorry, that was a bum steer. There is now a free CAD called freecad, which is no help to you, you need the product that was called freecad but is now distributed by ar-cad.
