为优化六自由度机械臂的动态性能,减少因角速度和角加速度急剧变化而导致的关节不稳定性和运动轨迹偏差的现象,本文采用七次多项式插值算法规划各关节轨迹.首先运用标准D-H参数法对六自由度机械臂仿真建模并分析其正逆运动学问题,其次机械臂采用蒙特卡洛法进行空间可视化仿真,从而精准确认机械臂运动时可以到达的空间位置,并结合机械臂的运动时间、位置、速度、加速度,选用七次多项式插值算法规划其运动轨迹,结果得出机械臂关节轨迹平稳光滑,有效解决速度、加速度乃至更高阶动力参数的突变点,提升了机械臂的运动准确性,降低了硬件损耗,具有实用价值.
Kinematic Modeling and Simulation Performance Analysis of Industrial Robot arm Based on Six Degrees of Freedom
In order to optimize the dynamic performance of a 6-DOF manipulator and reduce the joint instability and trajectory deviation caused by sharp changes in angular velocity and angular acceleration,the seventh-degree polynomial interpolation algorithm was used to plan the trajectory of each joint.Firstly,standard D-H(Denavit Hartenberg)parameter method was used to simulate the 6-DOF robotic arm and analyze its forward and inverse kinematics.Secondly,Monte Carlo method was used to visualize the working range of the 6-DOF robotic arm and determine the accessible working space of the 6-DOF robotic arm.Combined with the motion time,position,speed and acceleration of the manipulator,seventh-degree polynomial interpolation algorithm was used to plan the trajectory of the six-degree-of-freedom manipulator.The trajectory of the joint motion was smooth and smooth,which effectively solved the mutation points of speed,acceleration and even higher order dynamic parameters,improved the accuracy of the manipulator's motion and reduced the hardware loss,and had practical value.
