摘　　要：刀杆作为切削加工时重要的零件,因外力载荷产生的变形对制造和加工精度产生的影响不容忽视,为了解决此问题,根据弹性力学理论,建立了刀杆零件形体的形变三维模型,利用ANSYS有限元分析软件对刀杆零件的载荷形变及其分布进行了仿真,并进行了模型实验验证,给出了实例应用的分析,说明了其载荷形变模型在实际设计制造加工中的应用。结果表明,所建立的模型正确可靠,为合理进行零件的制造和加工提供了理论依据和参考。As the important parts in machining, the load deformation of tool rod has an important impact on manufacturing andmachining accuracy, it cannot be ignored. In order to solve this problem, based on the theory of elastic mechanics, the 3d de-formation models of tool rod parts are established. Based on the ANSYS finite element analysis software, the load deformationand its distribution of the tool rod part are simulated, and the model is verified by experiments. At last, the example applica-tion is given to illustrate application of the deformation model in actual design and manufacturing process. The results showthat the built model is reasonable and reliable, and it could provide the theoretical basis for the reasonable design of manufac-turing and processing.
