摘　　要：机架是耕整机上的重要结构,其品质好坏直接影响着耕整机的使用寿命。应用CATIA实现了耕整机机架模型的参数化建模,分析了耕整机工作时的受力情况,用有限元分析软件ANSYS完成对耕整机机架的有限元模型建立和强度、刚度分析,得到了机架的应力分布情况,对应力大的结构提出了改进措施,改进后效果较好。Frame of tillage machine is an important structure, the quality of which has direct impact on the life of tillage machine. Using the software of CATIA, the frame＇s parametric model of 3D entity is built. The analysis of typical condition is finished when tillage machine is working. The finite element model is built, the analysis of strength and stiffness is carried out by ANSYS, and the stress distribution is obtained. The improvement measures to the large stress structure are proposed. Some good results are obtained. This paper provides references for further improvement of frame and obtains a higher value in engineering applications.
