摘要

针对现有数值图谱法无法实现开区间设计要求的空间RRSS机构轨迹综合，基于小波分解理论提出了空间RRSS机构轨迹综合的方法。通过将空间RRSS机构轨迹综合问题转化为机构的基本尺寸型匹配识别问题和机构实际尺寸的计算问题，实现了开区间设计要求的空间RRSS机构轨迹综合，弥补了数值图谱法在求解开区间尺度综合问题上的不足。通过数值算例证明了提出方法的实用性和有效性。

Abstract

The existing numerical atlas methods can not realize open interval path synthesis of spatial RRSS mechanism. A path synthesis method of spatial RRSS mechanism is proposeed based on wavelet decomposition theory. By transforming path synthesis problem into the matching and identification problem of the basic types of mechanism，and the calculation problem of the actual sizes of mechanism，the open interval path synthesis of spatial RRSS mechanism is realized. Thus，it makes up for the deficiency of the numerical atlas method in solving the dimensional synthesis problem with open interval design requirements. A numerical example is presented to demonstrate the practicability and effectiveness of the proposed method.
