摘要
利用ABAQUS有限元软件,建立内燃机曲轴的有限元模型;通过曲轴的模态响应法进行曲轴的模态识别,计算出曲轴的扭转模态。根据计算结果评价曲轴设计,说明了用有限元法进行模态分析的可行性。
Using ABAQUS finite element software to establish the FEM model of the crankshaft; identifying the crankshaft modal by Mode-based steady-state dynamic analysis method; According to the calculation results to evaluate the crankshaft design. Illustrates the feasibility of using modal analysis based on the finite element method.
