摘　　要：以山地自行车铰接件为研究对象,运用SolidWorks Simulation和概念设计软件Altair Inspire对该零件进行模型初始静力学分析,结合初始强度对铰接件进行拓扑优化。对铰接件的米塞斯等效应力、位移变形以及安全系数等因素进行分析,在此基础上获得了零件优化后的结合模型,使其质量减轻42.85%,通过3D打印技术对该零件进行3种切片形式的模型制作,验证了设计模型的可制造性,为其他产品的轻量化设计提供可参考的案例。The technical advantages of 3D printing provide the key support for the research of personalized design and lightweight structure component manufacturing. Taking the mountain bicycle hinge as the research object, SolidWorks Simulation and Altair Inspire, the concept design software, were used to carry out initial statics analysis of the model of the part,and topological optimization of the articulated parts was carried out combining with the initial strength. Based on the analysis of Mises’ equivalent stress, displacement deformation, safety factor and other factors of the articulated parts, the optimized combined model of the parts was obtained, which reduced its mass by 42.85%. Three kinds of sliced models of the parts were made by 3D printing technology, and the manufacturability of the design model was verified. It provides reference cases for other lightweight design of products.
