本文提出了一种新型的具有1个平移和3个转动自由度的并联机器人,它可以被设计为飞机工业中大型部件装配的对接设备。首先,利用螺旋理论和闭环矢量法对新型机械手的移动性和运动学进行分析。为了评价该机械手的运动学性能,计算了其工作空间,推导了该机械手的齐次雅可比矩阵。主要基于非线性规划方法,运动学的尺寸综合进行优化,这种新型的并联机器人的尺寸参数在指定的工作空间。本文的研究结果可为新型并联机器人样机的设计和制造奠定坚实的基础。
SUMMARY This paper proposes a novel parallel manipulator with 1 translational and 3 rotational degrees of freedom, which may be designed as the docking equipment for large-scale component assemblage in the aircraft industry. First, the mobility and kinematic analysis of the novel manipulator is performed using the screw theory and the closed-loop vector method. To evaluate the kinematic performance of the manipulator, its workspace is calculated, and the dimensional homogeneous Jacobian matrix of this manipulator is deduced. Mainly based on a nonlinear programming approach, the kinematic dimensional synthesis is performed to optimise the dimensional parameters of this novel parallel manipulator in a prescribed workspace. The results of this paper may lay a solid foundation for the prototype design and manufacture of the novel parallel manipulator.
