Bridging the gap from coupon to component for new bushing materials
Deadline
Challenge
Bushings, or anti-vibration mounts, are widely used as connecting elements in mechanical systems such as suspensions and powertrains to allow a certain motion and flexibility while reducing vibration transmission. They typically consist of a rubber material inside a metal housing. In recent years, material suppliers started developing more sustainable alternatives to reduce or replace natural rubber, while preserving or improving the dynamic bushing performance. The dynamic behaviour of bushings is complex, involving material and geometric nonlinearities, and highly dependent on assembly, loading and boundary conditions, which makes characterization and modelling challenging. On the one hand, material suppliers seek strategies to predict the dynamic bushing performance based on material composition and parameters. On the other hand, component and system providers seek component models for system model integration.
Project goal
The project aims to bridge the gap between material coupon testing and actual bushing component performance through a comprehensive characterization and modelling framework, thereby also bridging dynamics from low-frequency handling to higher frequency noise and vibration performance.
