Study on 42CrNiMo Gear Contact Fatigue Strength Experiment

摘要

This paper makes study on the 42CrNiMo gear contact fatigue strength,applying the rapid measure method of the gear contact fatigue stress value with a few gear samples to get the estimated value of the gear fatigue limit value precisely and rapidly.And the gear fatigue life curve and fatigue damage accumulation curve are got by MATLAB simulation.Comparing with the traditional test method,this method can reduce the cost and save the time.
