Development of an extremely fatigue-resistant Shock Absorber

In English

Författare

Summary, in English

An extremely fatigue resistant shock absorber was developed from basic mechanics principles using nonlinear elastic material models and finite element analysis. Prototypes were manufactured and tested to confirm the calculations and to find out the fatigue properties. The rubber body fills a cavity at gradually increasing compression. This idea has some clear advantages: A large part of the rubber body is protected against accidental external influences and it is backed up during the deformation by the cavity walls. Also, the stress in the rubber body becomes evenly distributed as only compressive stress is developed in it. The prototypes were tested in nearly 6 million cycles with no visible defects.
