摘　　要：分析了TH65100卧式加工中心的前滑座,使用PRO/E软件建立机床前滑座的三维模型。通过PRO/E软件与ANSYS软件的嵌套,将PRO/E软件中的三维实体导进有限元分析软件ANSYS中,利用ANSYS软件的静力分析功能,对进给状态下的滑座做有限元计算,并根据计算结果校核了滑座的静强度。使用ANSYS软件中的拓扑优化模块对滑座结构进行改进。改进后的滑座结构保持了原结构的静强度和刚度,但比原设计方案的用料减少了36·95kg。The slide of the horizontal machining center TH65100 is analyzed, and the 3 D model of the slide is crea ted in PRO/E. Through the interactive interface between PRO/E and ANSYS, the 3D model of the slide is transferred into the ANSYS software. Using the static analyzing function of ANSYS, the slide in feeding state is finite element analyzed, then the static rigidity of the slide is checked according to the calculation results. Finally, the design of the slide is optimized by the topological optimization in ANSYS. Comparing with the original design, the weight of the optimized structure is reduced by 35.69kg, and the static intensity and stiffness of it are the same as original design.
