采用通用有限元软件Ansys9.0对农用运输车490型柴油机连杆进行了动态特性分析,获得了连杆的基本振型和相关频率。通过分析找出了连杆结构上的薄弱环节,为连杆结构优化设计提供理论依据。
The dynamic finite element analysis software Ansys9.0 was used to analyze the dynamic characteristics of the 490 diesel engine connecting rod. The basic vibration mode and related frequency of the connecting rod were obtained. Through the analysis, we find out the weak links on the connecting rod structure and provide the theoretical basis for the optimal design of the connecting rod structure.
