摘　　要：运用Denavit-Hartenberg方法建立了以关节角为变量的马鞍形焊缝焊接机器人运动学模型,对马鞍形焊缝焊接机器人正运动学和逆运动学问题进行了求解分析;采用三次多项式插值的方法对焊接机器人进行了轨迹规划,通过MATLAB Robotics Toolbox工具箱对马鞍形焊缝焊接机器人进行了运动学仿真,得到了焊枪末端轨迹图以及关节角、角速度、角加速度与时间的变化曲线,验证了所设计参数的合理性,达到了良好的效果。Based on the Denavit-Hartenberg (DH) method, the kinematic model of Saddle-shape weld robot is built in the basis of joint variables. The forward kinematics and inverse kinematics of saddle welding robot were analyzed. Trajectory planning of weld robot was based on the cubic polynomial interpolation method, using the MATLAB Robotics Toolbox to simulate the Saddle welding robot kinematics, the track figure of the welding gun terminal execution mechanism and the relation curves that angular displacement, angular velocity and angular acceleration vary with time were obtained. The rationality of the designed parameters is verified, and achieved good effect.
