混凝土泵车是一种大型工程设备,由于其臂架系统具有冗余自由度,因此对其运动进行规划具有很大实际意义。提出基于模糊算法的模糊梯度投影法,并应用其进行了具有2个冗余自由度的混凝土泵车臂架系统逆运动学问题的求解,进行了直线和圆弧轨迹浇注的仿真。结果表明在对给定的轨迹进行规划时可以减小末端轨迹误差,能够较好的求解混凝土泵车臂架的逆运动学问题。
Concrete pump truck is a kind of large-scale engineering equipment. Because of its redundant freedom degree of boom system, it is of great practical significance to plan its movement. A fuzzy gradient projection method based on fuzzy algorithm is proposed. The inverse kinematics of a concrete pump truck with two redundant degrees of freedom is solved. The simulation of straight line and circular arc trajectory is carried out. The results show that the end trajectory error can be reduced when planning a given trajectory, and the inverse kinematics of the concrete pump truck boom can be solved well.
