【摘要】：可变运动副作为变拓扑机构改变拓扑结构的关键所在,其结构设计是变拓扑机构构型综合的难点.基于可变运动副拓扑变化方式的研究,构建可变运动副设计目录,用于可变运动副的结构设计.分别针对可变运动副的改变轴线方位、改变数目和改变类型等三类拓扑变化过程,分析可变运动副的约束变化特征,并采用运动副约束函数的算术运算进行描述.在归纳设计可变运动副结构形式的基础上,对可变运动副拓扑变化方式、约束变化特征和对应结构等设计信息进行分类和汇编,构建可变运动副设计目录.应用实例表明,采用可变运动副设计目录,能快速有效地设计可变运动副结构,为含可变运动副的变拓扑机构构型综合提供了方便.
[Abstract]:The variable motion pair is the key to change the topology of the variable topology mechanism, and its structure design is the difficulty of the configuration synthesis of the variable topology mechanism. Based on the research of variable motion pair topology, the design catalogue of variable motion pair is constructed, which is used in the structure design of variable motion pair. According to the three kinds of topological change processes, such as changing axis orientation, changing number and changing type of variable motion pair, the constraint variation characteristics of variable motion pair are analyzed, and the arithmetic operation of motion pair constraint function is used to describe it. On the basis of summing up and designing the structure form of variable kinematic pair, this paper classifies and compiles the design information of variable kinematic pair, such as topology change mode, constraint change feature and corresponding structure, and constructs the design catalogue of variable kinematic pair. The application example shows that the variable motion pair structure can be designed quickly and effectively by using the variable motion pair design catalogue, and it is convenient for the configuration synthesis of the variable topology mechanism with the variable motion pair.
