Joint Speed Planning of 6R Gangue Selection Manipulator Based on Adams

设计了一种6R选矸机械臂并提出了一种三次S形加减速控制算法来提高其运动平稳性。首先建立梯形、7段S曲线加减速控制算法,通过分析这2种算法对机器人运动平稳性的影响,提出了一种三次S形加减速控制算法。利用Adams对3种算法进行仿真分析,结果表明新型的S形加减速控制算法在提高6R选矸机械臂的运动平稳性方面更具优势并为6R选矸机械臂后续的运动控制分析和优化奠定了基础。

A 6 R gangue selection manipulator is designed and a three-time S-shaped acceleration and deceleration control algorithm is proposed to improve the smoothness of its motion. Firstly, a trapezoidal and 7-segment S-curve acceleration and deceleration control algorithm is established. By analyzing the influence of these two algorithms on the motion stability of the robot, a cubic S-curve acceleration and deceleration control algorithm is proposed. Using Adams to simulate and analyze the three algorithms,the results show that the new S-shaped acceleration and deceleration control algorithm has more advantages in improving the smoothness of the 6 R loading and unloading robots, and lays the foundation for the subsequent motion control analysis and optimization of the 6 R loading and unloading robots.
