对于给定的刚体四位置,在布尔梅斯特曲线上任取两组位置点可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是比较困难的.本文提出将无穷多机构解用有限机构解域来表示,通过机构解域初步分析绘出机构属性图,据此设计者可了解每个机构的类型、最小传动角、杆长比以及有无缺陷等信息.其次施加约束条件构成可行机构解域,这样可避免位置点选取的盲目性.最后基于可行机构解域或感兴趣的区域绘制机构性能分析图确定机构最优解.
For a given four-body position, taking two sets of position points on the Bümmeter curve gives an infinite number of mechanism solutions, requiring the designer to quickly and accurately select the location from which to synthesize the best mechanism to meet the design requirements More difficult.This paper proposes to use an infinite number of institutions to solve the finite body solution domain to represent it, and to draw the institutional attribute chart through the preliminary analysis of the agency solution domain, by which the designer can know the type of each agency, the minimum transmission angle, As well as the existence of defects and other information.Secondly, the constraints are imposed to form feasible solution domain, so as to avoid the blindness of location selection.Finally, the optimal solution of the mechanism is determined by drawing the mechanism performance analysis map based on feasible solution domain or region of interest.
