针对并联机构的强耦合性问题,提出了一种新型无耦合两移动并联机构,包含3条分支运动链,其中,第一条和第二条分支运动链结构相同,均为RURR型结构,第三条分支运动链为由3个轴线平行的转动副组成,且其为纯约束分支。基于螺旋理论分析了机构的自由度和输出特性;利用驱动力螺旋和封闭环矢量法建立了机构运动学模型,推导出机构的位置、速度和加速度方程;详细讨论了机构的奇异性,得出机构的奇异位形;应用Matlab和Adams软件进行运动学仿真,仿真结果验证了理论分析的正确性。
Aiming to solve the strong coupling problem of parallel mechanism, a novel uncoupled two-translational parallel mechanism is proposed, which includes three branch chains. The first and the second branch chains have the same structure, they are all RURR-type structures. The third branch chain, called a pure constraint branch, is composed of three rotational joints whose axes are with parallel to each other. Based on the screw theory, the degree of freedom and output motion characteristics of the mechanism are analyzed. The kinematics models of the mechanism are established by using the actuation screw wrench theory and the closed loop vector method. Position, velocity and acceleration equations are derived. Singularity is also analyzed in detail and the singular configurations of the mechanism are obtained. The kinematics simulation is performed by using Matlab and Adams software. The correctness of the theoretical analysis is verified by the simulation results.
