摘　　要：运动分析是平面四杆结构研究的重要内容,对于机构设计具有重要指导意义。本文基于平面四连杆机构设计原理,利用解析法求出四杆机构各结点的坐标,以达到对其进行运动分析的目的。即首先建立机构的矢量方程,对其求解得到各杆件运动的角速度、角加速度和角位移等的数学模型。在此基础上利用VB编程采用模块化设计,开发了平面四连杆机构可视化运动分析软件。实际应用证明,该软件界面友好,功能全面,能够实现铰链四连杆机构的交互设计、关键点位移、角速度、加速度曲线绘制及分析和运动动画仿真等,为平面连杆机构的分析计算提供了方便,同时也提高了四杆机构的设计效率。本文介绍的方法和成果,同样适用于其它类型机构的运动分析及仿真。Motion Analysis is an important content of the study of planar four-shank structure, and it is important to structure design. In order to analysis the motion of planar four-shank structure, the analytics method was used to obtain the node＇s position, which based on planar four-shank design theory. Firstly, establish the vector equations of the structure, and then obtain the mode of the links＇ angular velocity, acceleration and angle. The planar four-shank structure visual motion analysis software was developed with VB program. It is proved that the software is friendly of user interface and versatility, and has the function of four-bar linkage structure interactive design, position motion of key nodes and angle velocity analysis, drawing of acceleration curve and animate simulation, etc, which offer convenient for planar four-shank structure＇s analysis and calculation, and improve the design efficiency of four-shank structure. The method and resulting of this paper can also apply to the analysis and simulation of the similar mechanisms.
