What's happening?

    Hi Martin, yes, I think I'm over simplifying the suspension and that's complicating the dynamics. The auto engineers (SAE) use the concept of a roll centre, which is derived from the suspension geometry - the suspension rotates about this imaginery axis which in turn means the car body rolls about this axis. I think we can neglect the conservation of angular momentum of the car body because of...

    Hi Martin, I'm probably just confusing myself as usual but I'm having trouble with modelling different inertias in a multi-body system like a car. Currently I have a simplified model - there's one inertia tensor and mass of the whole car - i.e. the sprung plus unsprung masses. Road forces (i.e. on the tyres) are split between verticle and horizontal components. The horizontal components...
