基于Pro/E和ANSYS发动机连杆模态特性分析

Dynamic Characteristics Study of Connecting Rod Based on Pro/E and ANSYS

采用三维绘图软件Pro/E建立发动机连杆的三维模型,并在有限元分析软件ANSYS中建立连杆的有限元模型。对连杆进行了动态特性分析,得到了连杆的固有频率和每一模态下的振型,为高性能的连杆设计提供了理论依据。

The 3D model of the connecting rod was set up by using the software Pro/E.Then the finite element model was set up through the software ANSYS.Dynamic characteristics analysis of connecting rod was carried out in ANSYS,the mode frequency and mode shape were obtained,which could provide the theoretical basis for design of connecting rod.
