摘　　要：现有的锁紧块结构单一,且对孔轴的配合精度要求高,这对使用和加工带来诸多不便。通过对现有常规锁紧结构进行优化,以达到宽裕的配合精度和轻量化产品。首先通过拓扑优化,然后根据优化结果和设计经验进行结构的形状优化,再进行尺寸优化,得到最优尺寸参数,最后通过疲劳分析进行校核。结果显示:优化后的模块的重量减轻38%,使用同样锁紧力作用下,检测点P点的变形量是原变形量的2.24倍,达到轻量化设计和宽裕的配合精度,同时5年工况环境可以满足使用。说明使用拓扑优化可以实现产品初期设计和产品的轻量化设计,仿真可完成具体的尺寸参数优化和疲劳强度校核。The existing locking block has a single structure and requires high matching accuracy of the hole shaft.This brings a lot of inconvenience to use and processing.By optimizing the existing conventional locking structure,it can achieve ample matching precision and light-weight products.First,topology optimization is performed Topology Optimization,and then the shape of the structure is optimized according to the optimization results and design experience,then perform size optimization to get the optimal size parameters,and finally check it through fatigue analysis.The results show that the weight of the optimized module is reduced by 38%.Under the same locking force,the deformation of the detection point P is 2.24 times of the original deformation,achieving a lightweight design and ample coordination accuracy,and a 5-year environment the working conditions can satisfy the use.It shows that the use of topology optimization can realize the initial design of the product and the lightweight design of the product,and the simulation can complete the optimization of specific size parameters and the check of fatigue strength.
