Performance Examination about the Remanufacturing Engine Crankshaft Based on the "Size Recovery”

A new 3D crankshaft model and a re-manufacturing one were built respectively together with piston, link and etc., According to the static structural module and the fatigue module embedded in ANSYS workbench, their stress distribution charts and fatigue life charts were obtained. By comparison, it can prove that fatigue life of the re-manufacturing crankshaft is very close to new one.
