摘要:

本文提出了一种新的具有柔性连杆和柔性驱动关节的多链并联机器人刚度建模方法。与其他工作相比,该方法涉及基于有限元分析的连杆刚度评估,并采用了一种新的解决方案的动力学方程,它允许计算奇异姿态的刚度矩阵,并考虑到外力的影响。应用实例验证了该方法的优越性,并对一种并联机器人进行了刚度分析

英文摘要:

The paper presents a new stiffness modelling method for multi-chain parallel robotic manipulators with flexible links and compliant actuating joints. In contrast to other works, the method involves a FEA-based link stiffness evaluation and employs a new solution strategy of the kinetostatic equations, which allows computing the stiffness matrix for singular postures and to take into account influence of the external forces. The advantages of the developed technique are confirmed by application examples, which deal with stiffness analysis of a parallel manipulator of the Orthoglide family
