摘要/Abstract

摘要： 建立了6160柴油机曲轴三维有限元分析的改进模型，详细介绍了曲轴在弯曲和扭转2种交变应力状态下，其位移边界条件和载荷边界条件的确定以及加载方法，校核了该曲轴提高功率前后的疲劳强度. 计算结果表明，该模型能够很好地模拟曲轴的实际工作状况，为进一步分析曲轴提供了新思路.

关键词: 曲轴, 有限元分析, 边界条件, 疲劳强度

Abstract: An improved Finite Element Analysis(FEA) on the crankshaft model of 6160 diesel engine is presented. Displacement boundary conditions and loading boundary conditions as well as loading method under alternating stress status of bending and torsional load are introduced in detail. Based on the improved crankshaft FEA model and boundary conditions, the crankshaft fatigue evaluations before and after power updating are made. The result shows that the improved model simulates the working condition of 6160 diesel engine crankshaft practically, and thus provides useful guidance for optimal crankshaft design.

Key words: FEA, boundary conditions, fatigue strength , crankshaft
