| Abstract: | Based on the software of AVL Excite Power Unit, Multi-body dynamic method is used to calculate the crankshaft main journals and webs force and moment. Then use the software of MSC.Fatigue combining the method of finite element analysis to caculate the safety factor of crankshaft fillet model using the results of multi-body dynamic as the loads spectrum. These all may establish a basis to analysis the safety of engine crankshaft. |
