Automotive Suspension Bumpers - A Correlation of Parameters Affecting Impact Response and a Technique for Achieving Effective Design 680471

Using laboratory test equipment, the impact performance of suspension bumpers has been studied as a function of bumper geometry, hardness, and composition at impact severities typically encountered in automobile suspension systems. The data can be useful in designing bumpers for minimum impact force transmission, soft entry, low rebound, deflection control, and other desired performance criteria.
The impact force, deflection, and entry characteristics are shown to be related primarily to the shape and hardness of the bumper, while rebound is found to be predominantly influenced by the choice of elastomer. Graphical technique; have been developed to facilitate the determination of optimum bumper designs to satisfy space limitations and performance requirements. Typical design situations are discussed.
