Dynamics Simulation and Crankshaft Dynamic Stress Analysis of 6L21/31 Marine Medium-speed Diesel Engine

摘要：

　　In order to solve the problem of some cracks appearing in certain parts of the crankshaft for 6L21/31 diesel engine,the completed multi-rigid body virtual prototyping (VP) model of the diesel engine was established on the basis of the virtual prototyping technology,and the dynamics characteristic analysis was finished.Then,based on the completed flexible-rigid model of 6L21/31 diesel engine,the dynamic stress analysis of the crankshaft was accomplished,and the maximum stress value and its location were got.The results provided the basis for the improvement and optimization of the crankshaft.
