Abstract
Jounce bumpers act as suspension limiters during impact. They prevent the suspension from getting into kinematic singularity situation during shock impacts due to potholes, curbs, and debris on the road. A Jounce bumper is manufactured of hyperplastic materials to make use of the viscoelasticity characteristics allowing it to be a better absorber that minimizes transmitted forces to the vehicle body for failure prevention. Therefore, it is essential to create accurate models for reliable and practical bumpers testing and design optimization before manufacturing. In this work, we will provide a modelling approach to evaluate the static performance of some traditional jounce bumpers. The model accuracy was evaluated using standard bumper tests and found to have a good agreement.
