Elastokinematics
Road irregularity not only causes vertical but also horizontal impact forces at the tire contact centre.
For these to be moderated and transmission of vibration and noise to the body to be minimized, instead of rigid joints, rubber mounts are usually used between suspension components and the body.
→The elasticity of these rubber mounts produces wheel position changes as a result of wheel forces and torques acting on the suspension.
→Magnitude and direction of displacement is determined by the design and geometries of links and elasticities of rubber bushes.
