摘　　要：研究平面连杆机构动态特性,为提高动态技术性能,采用封闭矢量法分析推导了牛头刨床平面六杆机构运动学求解数学模型。在此基础上,采用软件开发了一套适用于平面六杆机构的运动学仿真系统。在MATLAB平台上进行了牛头刨床主体机构的运动学仿真与动画显示,绘制出了连杆的角度、角速度和角加速度曲线以及滑块和滑枕的位移、速度和加速度曲线。结果证明,该系统不仅分析机构直观方便,通过改变参数后能实现机构优化运动特性,并为设计提供依据。The paper established the kinematics model of the planar six-bar mechanism of shaper by closed-volume method.On the basis,using MATLAB/GUI toolbox,a kinematics simulation system applied to planar six-bar mechanism was developed by means of MATLB programming.And it was used for the kinematics simulation and animation display of shaper,furthermore,simulated the figure of angle,angular velocity and angular acceleration of link and the figure of position,velocity and acceleration of slider and ram.The result proves that this system can be used to analyze institutions conveniently and intuitionally and the change of mechanism kinematics characteristics is achieved by changing parameters.
