摘要:

基于多目标优化设计方法,对平面并联机器人结构进行了比较。机械手架构进行了比较,关于他们的运动质量和他们的规则工作空间的大小,即,目标函数。优化问题受到机械手灵活性和刚度的约束。对于给定的外扳钳,在所获得的最大规则灵巧工作空间内,动平台的位移必须小于给定值。本文的贡献突出与3-RPR,3-RPR和3-RPR平面并联机器人的结构,这是比较通过他们的帕累托前沿与遗传算法获得的研究。

英文摘要:

This paper deals with the comparison of planar parallel manipulator architectures based on a multi-objective design optimization approach. The manipulator architectures are compared with regard to their mass in motion and their regular workspace size, i.e., the objective functions. The optimization problem is subject to constraints on the manipulator dexterity and stiffness. For a given external wrench, the displacements of the moving platform have to be smaller than given values throughout the obtained maximum regular dexterous workspace. The contributions of the paper are highlighted with the study of 3-RPR, 3-RPR and 3-RPR planar parallel manipulator architectures, which are compared by means of their Pareto frontiers obtained with a genetic algorithm.
