面向抓取和分拣等场合,提出一种新型三移动一转动2PRP,a,U-2PSS并联机构,对其进行了运动学分析。应用方位特征集理论分析了机构约束特性、自由度和结构耦合度;根据杆长约束条件,建立机构位置分析非线性方程组,将位置正解问题转化为求一元方程,并应用改进灰狼优化算法求解该问题;推导出机构速度和加速度正逆解解析表达式;给出机构运动学分析数值算例,根据理论模型,运用Matlab软件绘制位移、速度和加速度曲线,同时应用Adams软件进行了仿真验证。结果显示,理论分析与数字仿真结果一致,表明给出的运动学分析模型和计算方法正确可靠。
Facing the occasion of grasping and sorting, a novel 3T1R planar symmetric parallel mechanism, named 2PRP,a,U-2PSS PM, is proposed, and its kinematics is analyzed in detail. The degree of freedom and coupling degree are addressed through the position and orientation characteristic (POC) theory. The mathematical models of displacement and orientation, velocity and acceleration analysis are derived by utilizing the vector method. Meanwhile, the nonlinear equations of forward displacement are transformed into one-dimensional equation, thus using the improved grey wolf optimization algorithm to solve this problem. A numerical example is given to verify the correctness of the kinematical mathematical model, the displacement, velocity, and acceleration curves are obtained with the aid of Matlab, and then Adams is used for simulation verification. Finally, the two results are basically consistent, which indicates that the kinematic mathematical models of the discussed mechanism derived are correct and reliable.
