Abstract

For the cylinder block of Vtyped diesel engine, the fatigue test methods of two load forms were researched and the bulkhead fatigue life distribution was calculated and compared. The results show that the fatigue life distributions at bulkhead are hardly affected by different load forms. The bench test was further conducted by centralized loading to verify the result, which provided the reliable reference for loading method of future fatigue test.
