| 摘 要： | 对于给定的两连架杆4组对应角位移,可综合得到无穷多个机构解,要求设计者快速、准确地从中选取位置点、综合出满足各项设计要求的最优机构比较困难.为此,根据映射理论,提出把无限的布氏曲线所形成的无穷多机构解表示在有限的区间内,进而通过机构解分析得到感兴趣的所有机构属性直观图,包括机构的类型分布、缺陷分布、最小传动角和杆长比等.同时,为避免位置点及机构选取的盲目性,可考虑施加约束条件构成可行机构解区间,在此区间上绘制机构性能分析图,并确定满足实际工程需要的最优机构解.

| Abstract: | An infinite number of linkages can be produced for given four angle-displacements of rotating links.It is difficult for designers to synthesize the best linkage through rapidly and precisely selecting curve points that ensure to satisfy every design condition.To solve this problem,based on mapping theory,an infinite number of mechanism solutions generated by Burmester curves were expressed as finite solution ranges.Through solution analysis,the mechanism property graphs of interest have been computed,includ... |
