设计了一种可以实现两移一转的新型3自由度并联机构3-UPS/RPP。该结构在传统的3-UPS结构基础上加入了一条RPP结构的约束支链,应用螺旋理论分析约束链得知,该3-UPS/RPP并联机构可实现平面内的一维转动和二维移动。在自由度分析的基础上,构建了3-UPS/RPP并联机构的运动学模型,通过对驱动支链和约束支链的分解分析,给出了3-UPS/RPP并联机构位置逆解的解析表达;随后,基于位置逆解结果,确定了工作空间的搜索流程,并据此在Matlab软件中求解了该机构的工作空间;最后,对该3-UPS/RPP并联机构进行了运动学控制仿真。结果表明,系统具有较高的动态轨迹跟踪控制精度,适用于实际应用。
Abstract A new 3-DOF parallel mechanism 3-UPS/RPP is designed, which can realize two shifts and one rotation. Based on the traditional 3-UPS structure, a constrained branched chain of RPP structure is added to the structure. The spiral theory is applied to analyze the constrained chain. It is found that the proposed 3-UPS/RPP parallel mechanism can realize one-dimensional rotation and two-dimensional movement in the plane. On the basis of degree of freedom analysis, the kinematics model of 3-UPS/RPP parallel mechanism is further constructed. Through the decomposition analysis of driving and constrained branching chains, the analytical expression of inverse solution of position of 3-UPS/RPP parallel mechanism is given. Based on the results of inverse solution of position, a workspace search process is constructed, and the workspace of the mechanism is solved in Matlab software. Finally, the kinematics control simulation of the 3-UPS/RPP parallel mechanism is carried out. The simulation results show that the system has high dynamic trajectory tracking control accuracy and is suitable for practical application.
