A viscoelastic bump stop model for multi-body simulations based on impact test data
The studied bump stop is a hollow folded polyurethane cylinder mounted around the damper rod in a MacPherson front wheel suspension, restricting the upward wheel displacement. It is a critical component for durability since the force transfer through the bump stop determines the vertical peak loads to the car body. In extreme load cases as driving over a curb, the bump stop is subjected to impact
