以摆线针轮减速器为对象建立产品的ＤＦＭ体系结构，研究面向制造的减速器虚拟产品设计的关键技术：产品总体设计、零件特征造型、特征评价、制造资源库的建立、设计方案评价及再设计、产品变型设计及装配分析等，并开发了原型系统。该原型系统的开发有利于ＤＦＭ技术和虚拟产品开发技术的研究。 The DFM architecture of the cycloid reducer is established to study the key technologies of the reductant virtual product design for manufacturing: product design, part feature modeling, feature evaluation, manufacturing resource repository, design evaluation and Redesign, product variant design and assembly analysis, and developed a prototype system. The development of this prototype system is conducive to the research of DFM technology and virtual product development technology.
