摘要:

本文提出了一种基于工作空间网格概念的并联机器人整体优化设计方法,并利用目标达成公式进行全局优化。为了结合非均匀设计规范,开发的优化技术将所有的约束和目标转换成类似的性能指标相关的最大尺寸的规定形状的工作空间。这种转换是基于专用的动态规划程序,满足现代CAD的计算要求。所开发的技术的效率证明通过两个案例研究,处理优化的运动学和刚度性能的并联机器人的cylidide家庭。

英文摘要:

The paper proposes an integrated approach to the design optimization of parallel manipulators, which is based on the concept of the workspace grid and utilizes the goal-attainment formulation for the global optimization. To combine the non-homogenous design specification, the developed optimization technique transforms all constraints and objectives into similar performance indices related to the maximum size of the prescribed shape workspace. This transformation is based on the dedicated dynamic programming procedures that satisfy computational requirements of modern CAD. Efficiency of the developed technique is demonstrated via two case studies that deal with optimization of the kinematical and stiffness performances for parallel manipulators of the Orthoglide family.
