Fatigue Tests on Connecting Rods

Fatigue Tests on Connecting Rods

The complex of loads acting on connecting rods requires a design equal to the demands placed on it. This also applies to the materials used. The fatigue limit for connecting rods is assumed to be approx.  N=5x106 cycles and the connecting rod can be divided into three load areas (blue markings). Both eyes must be tested under actual conditions, i.e. with play and in a temperature range from 90 – 120°C, surrounded by oil . 

The Zwick vibrophore, with special forked specimen-holder, allows a test frequency of up to 250Hz. High specimen throughput and low energy requirements mean reduced operating costs.
