摘　　要：文章提出了根据型综合与尺度综合的设计结果将机构运动简图在空间展开的方法。建立机械系统的状态变换空间,将运动方案设计转换为状态空间中的路径规划问题。将运动状态变换方程转化为特征状态变换方程,利用构型综合的特征状态空间方法得到概念构型。将系统的运动性能分配到每个机构,调用机构单元的尺度综合算法,得到对应机构的尺寸信息。以基本机构作为基本的绘图单元,利用坐标变换来实现机构图元连接,并详细说明了将机构运动方案展开的具体方法。对机构简图的生成过程开发相应的程序,并给出了具体的设计实例。This paper presents the method of automatically drawing the mechanism kinematic diagram based on the design results of type synthesis and dimension synthesis. By establishing the state space of mechanical system,the motion scheme design is transformed into the path planning in state space. Through converting the motion state transformation equation into the characteristic state transformation equation,use the method of characteristic state space to obtain concept configurations. Distribute the motion performance of system to each mechanism and call the dimension synthesis algorithm of mechanism unit to get main dimensions of the corresponding mechanism. Take basic mechanism as the basic drawing unit and use coordinate transformation to realize the connection of mechanisms. The specific method of generating schematic diagram is explained in detail. At last,develop the corresponding program and the specific design examples are given.
