Hello everyone,
So I am working on our first FSAE car and using ADAMS for MBD analysis. So far it has been wonderful progress, the subsystems of front & rear suspensions and steering has been modeled succesfully.
These subsystems work perfectly fine individually (or steering+front suspension) on a 2 post suspension test-rig. But when they are assembled with tires and body in full body assembly I am not able to run even a single sim. I get a static equilibrium failed error even during simplest simulation of straight line with free steering.
I have used the body model of FSAE templates on ADAMS website. So far I have checked communicators, joints and individual subsystems but I am not able to pinpoint the exact cause. The way I have modelled it is that all the element of suspension hook up to the mount part "suspension_to_chassis" and that particular part is hooked upto the body using communicators for mounting.
I have searched a lot for this but am finally posting here being clueless:
1) I understand this error seems most likely that my model is not being assembled properly. How can I pinpoint this problem? (they work fine individually..!!)
2) I am reading the term 'static funneling'. how do I use static funneling? (sorry if it seems stupid). I can only change few stuff under solver menu under settings.
3) Other terms I hear is Debug/Eprint. What are they being referred to?
Hoping for positive replies.
