利用 CAD／CAM 软件Inventor 的建模和分析功能，得到了3 GC－160型悬挂式果园割草机的质心位置，通过等效质心法对割草机的三维模型进行简化，将其通过接口导入 ANSYS Workbench 有限元分析软件中，对模型进行静力学分析和模态分析，得到悬挂装置的变形、应力、应变分布云图及模态频率和振型云图。分析结果表明：悬挂装置设计合理，可为动力学分析和后续优化设计奠定基础并提供参考依据。

The centroid of 3 GC-160 suspended orchard mower is obtained by using the CAD /CAM software Inventor which has the capabilities of modeling and analysis .Using the method of equivalent centroid three-dimensional model of the mower is simplified .Three-dimensional model is imported into the finite element analysis software ANSYS Work-bench by interface .ANSYS Workbench make the static analysis and modal analysis for the model .The analysis results show the contours of deformation , stress and strain , modal frequencies and mode shapes .Final results show that the de-sign of suspension is reasonable .And it lays the foundation and provides a reference for the analysis of dynamic and sub -sequent optimal design .
