| Abstract: | Taking one of the Cummins crankshafts for example,a 3-dimentional solid model of onecrutch crankshaft is created by means of Pro/E. The displacement and stress fields of crankshaft of three different kinds of material are calculated. The fatigue strength of the crankshaft under the alternative loads is analyzed using the general CAE software HyperWorks. The structure of crankshaft is also optimized with one of the module of the HyperWorks OptiStruct. |
