Abstract： CATIA V5R20 software was utilized to build up a three-dimensional solid model of inline four-cylinder gasoline engine crankshaft. The free modal analysis of the first six orders from the whole crankshaft model was carried out based on TGrid algorithm by using ANSYS Workbench14.0 software and the natural frequency and vibration modes were obtained. The reliability of the finite element model was verified by comparing with modal test result. This provides a reference for further design and optimization of the crankshaft.
Key words： ANSYS workbench; model analysis; natural frequency; vibration mode

摘要:利用CATIA V5R20软件建立了直列四缸汽油机曲轴的三维实体模型， 再利用ANSYS Workbench14.0软件基于TGrid算法对整个曲轴模型进行前6阶自由模态分析， 得出曲轴的固有频率和振型， 并通过模态敲击试验进行对比， 验证了有限元模型的可靠性， 为曲轴的进一步设计以及优化提供了重要参考依据。
