| 摘 要： | 采用改进的多体系统建模理论对激光拼焊生产线运动误差进行研究。用低序体阵列描述多体系统拓扑结构,用特征矩阵表示多体系统中间体的相对位置和姿态。在基于多体系统理论的误差建模基础上提出位置误差传递函数的概念,用来描述各个误差源对位置精度的影响。根据激光拼焊生产线的结构特点,运用改进的多体系统理论精度分析理论,对激光拼焊生产线运动精度进行系统、全面的分析。采用Leica激光跟踪仪对激光拼焊线的运动误差进行检测,并将检测结果与误差模型分析结果进行对比,结果表明所建立的模型能有效预测激光拼焊线的运动误差。

| Abstract: | Research on error modeling of tailored blank laser welding machine which has four linear axes is introduced. The number arrays of low-order body are used to describe the topological structures which are taken to generalize and refine MBS,and the characteristic matrices are employed to represent the relative positions and gestures between any two bodies in MBS. Position error transfer function which can reflect the influence of each error origin on the positioning error of the machine tool is given to descri... |
