I'm beginning to wonder if the problem lies with the setup of the simulink model. Even if i don't need the gravity component it still doesn't seem to explain the extremely high frequency vibration I am seeing. I've realized I've set my position and velocity integrator blocks' initial...

Hello all I am trying to derive a quarter car model that i can use Simulink to analyse. The model is 2 DOF and consists of 1 sprung and 1 unsprung mass, suspension spring and damping co-effs, and tyre spring and damping co-effs. Positive is taken as upwards, compression is also taken as...

so now I am thinking that my initial calculations were wrong and i should be coming up with expressions in terms of angular velocity. the way i see it, having an initial high degree of slip will produce a forward facing frictional force that causes the positive linear acceleration of the...

sorry, realized my explanation of the angular velocity was a bit vague. Essentially the disc will be 'spun up' to its initial angular velocity (values will range between 5,000 and 10,000 rpm) and then dropped from its initial position. The disc will rotate clockwise in the diagram above, so as...

see diagram a circular disc of radius r has an initial angular velocity \omega and rolls down a quarter circle ramp of radius R. The initial angular velocity will be very high (e.g. 10,000 RPM) causing the disc to slip. The normalised longitudinal force (i.e. longitudinal force / maximum...
