机器人逆运动学分析与仿真

研究机器人动态优化问题。根据机器人所持焊枪的运动轨迹,针对机器人可沿空间任意直线轨迹焊接,是焊接机器人关节控制策略中的难点,运用ADAMS软件对焊接机器人进行逆运动学求解,采用拉格朗日方法建立了系统的微分方程,运用pro/E建立了焊接机器人的三维模型,导入ADAMS中添加约束关系和设置仿真参数后建立焊接机器人的虚拟样机模型,对机械手沿空间任意直线轨迹运动的工况进行了逆运动学仿真,得到了各关节的角速度和角加速度曲线,并根据仿真结果提出了使焊接更加平稳的改进方案,结果表明方法不仅为焊接机器人的路径规划提供了参考数据,而且保证了焊接机器人在焊接过程中优良精确的动态特性和静态特性,具有重要的工程实际意义。

An Inverse Kinematics Simulation and Analysis for Robot

Calculating the corresponding joint variables according to the trajectory of the welding torch held by a robot is the difficult in welding robot joint control strategy.To solve the problem,a system of differential equations is established in this paper by using ADAMS software welding robot inverse kinematics and Lagrange methods.A three-dimensional model of welding robot is established by using pro/E,ADAMS add constraint relations are introduced and simulation parameters are set up to establish a virtual we...
