摘　　要：通过三维建模软件Pro/E建立6300柴油机曲轴的简化模型,再将其导入到有限元软件ANSYS,然后运用Block lanczos法对曲轴进行模态分析,得到曲轴的前9阶固有频率与振型,为曲轴的优化设计和动态响应奠定基础。By using the simplified model of the crankshaft of 6300 diesel engine built by Pro/E software,then import it into the finite element software ANSYS,and the method of Block lanczos is used in the modal analysis in order to get crankshaft＇s natural frequencies and flapping types of the first 9 orders,which supplies foundation for the optimization design and dynamic response of crankshaft.

关 键 词：曲轴 ANSYS 模态分析 固有频率 振型
