摘要：

以某型数控闸式剪板机为研究对象，运用应变电测技术对机床在典型工况下的真实的刚性性能进行测试，分析影响剪板质量的因素，再利用大型通用有限元分析软件对剪板机整体建模并进行仿真计算，描述了剪板机刀架及工作台的挠曲变形情况。根据有限元仿真结果与测试数据的对比，验证了剪板机变形趋势与实验测试结果基本一致，为后续的优化设计提供了可行性，通过分析找出了机床结构中的薄弱环节，提出了增加垫铁限制某方向位移、修改几何结构及尺寸、改变加强梁形状等优化设计方案，探讨了各参数变化对机床刚性的影响，优化后该型剪板机的刚性和剪板质量显著提升。

For a CNC gate-type shearing machine, the real rigidity of the machine under typical working conditions was tested by strain electric measuring technology, and the factors affecting the shearing quality were analyzed. Then, the model and simulation calculation of the overall shearing machine were conducted by the large-scale general finite element analysis software, and the deflection and deformation of tool holder and worktable for shearing machine were described. According to the comparison between finite element simulation results and test data, it was verified that the deformation trend of shearing machine was basically consistent with the experimental test, which provided the feasibility for the subsequent optimization design. Furthermore, the weak links in the machine tool structure were found, and several optimization design schemes were proposed, such as adding the shim to limit the displacement in a certain direction, modifying the geometric structure and sizes, and changing the shape of reinforced beam, and the influences of various parameters on the rigidity of machine tool were discussed, Thus, the rigidity and shearing quality of this shearing machine after optimization were significantly improved.
