Accuracy Synthesis of 2UPS-RPU Parallel Manipulator Based on Orthogonal Design

  • 摘要: 针对并联机构各原始误差对位姿误差的影响程度不同,使用穷举法在整个工作空间中进行精度综合计算量太大的问题,提出一种原始误差影响因子加权法与正交设计法相结合的精度综合方法。以2UPS-RPU并联机构为对象进行精度综合,并对综合结果进行验证。验证结果表明:该方法能够快速地得到22项误差源的公差值,且在整个工作空间内,末端位姿误差δy、δz、δα、δβ超出给定范围的概率仅分别为4.5%、2.08%、0.25%、2.16%,分析结果也验证了此方法的可行性与正确性。
