摘　　要：为降低镗轴滑枕刚度、固有频率、重量等对加工零件精度的影响,以TX-1600G镗铣加工中心镗轴滑枕为研究对象。应用结构拓扑优化SIMP法并结合折衷规划法和功效函数法,通过间接法建立镗轴滑枕有限元拓扑优化模型,以应变能和模态特征值为综合目标函数设计响应,结构体积为主要约束条件,进行拓扑优化并综合加工工艺等其它因数。在此基础上对比了几种筋板布局,发现双X形筋板综合性能最佳,选用该种筋板对滑枕进一步优化,完成了旨在提高镗轴滑枕动静态特性的多目标优化设计。并与原结构进行对比,验证了结构优化的有效性。为加工中心其他部件的拓扑优化及后续形状、尺寸优化提供了参考数据和基础。In order to solve the influence of boring axis sliding pillow stiffness,natural frequency,weight on the accuracy of parts. Use TX- 1600 G boring- milling machining center boring axis sliding pillow as the object of study. Apply topology optimization of SIMP method with the compromise programming method and the efficacy coefficient method,through indirect method to establish the boring axis sliding pillow finite element model of topology optimization,the strain energy and modal characteristic value as the design response of the composite objective function,the structure volume as the main constraints of topological optimization,and considering the processing technology and other factor aims. On this basis,through the comparison of several kinds of rib plate layout,it is found that the comprehensive performance of the double X shaped rib is the best,and the reinforcement plate is used to optimize the sliding pillow to complete the multi- object optimization design to improve dynamic and static characteristics of boring axis sliding pillow. Compared with the original structure,which verifies the validity of the structure optimization. Provides reference basis for the topology optimization of machining center and other components and the subsequent shape,and size optimization.
