Engine Crankshaft Remanufacturing Life Prediction and Experimental Verification

Abstract:

In this paper, the engine crankshaft remanufacturing life was estimated before and after. As long as the known material properties, loading, local stress, and then select the appropriate fatigue damage model can predict the fatigue life estimation. Material parameters of the experiment and the approximate method are obtained; load is on the basis of dynamic simulation; local stress obtained by finite element analysis; injury models were selected: the uniaxial damage model S-N method and multi-axis model of damage is strain method, SWT-Bannantine method, shear strain method, Fatemi-Socie method. New crankshaft and 500 hours, 1000 hours and 3000 hours after the crankshaft bench fatigue tests were conducted, and the experimental results were compared to verify the correctness of the theoretical calculation, and explain the crankshaft to remanufacture the fatigue life is sufficient.
