| Abstract: |
| As the core components of diesel engine, the structure and dynamic characteristics of the crankshaft has a vital role on engine performance. To Process the lightening hole with properly size in a certain location can reduce the weight of the crankshaft so as to, improve the dynamic characteristics and the connecting rod load of the crankshaft. Using finite element method and using three-dimensional software to model, the structural static and dynamic analysis theory to are gotten the performance and fatigue life analysis of crankshaft which have lightening hole with appropriate size. In this paper, to select the lightening hole for 25 mm size to analyze and compare the results with no hole of crankshaft analysis data can get that lightening hole can improve the crankshaft strength and the fatigue life of some location of the crankshaft. |
| Key words:
crankshaft
