Front View Geometry and Roll Center Height

1. The body roll depends upon the distance between C.G. of the vehicle and the R.C. Thus, if the RCH increases the effect on the body roll cannot be directly stated unless the C.G. height is specified.

2. 1. When the R.C. is on the ground plane, then there will be no non-rolling moment and and rolling moment will depend on C.G. height.

2. When the R.C. is below the ground plane, the non-rolling moment will come into existance and rolling moment will again depend on C.G. height.

3. In real vehicle, the kinematic roll center will be more accurate because it is directly determined based on solid links whereas the force based roll center is determined by verticle component of the lateral force, thus it may have approximations upto some extent.
