Multi-body Dynamics Software to Analyze Suspension Systems

Multi-body Dynamics Software to Analyze Suspension Systems

Multi-body Dynamics Software to Analyze Suspension Systems

(OP)
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

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
