考虑制造误差的计算机辅助机构误差分析

Computer-aided Mechanical Error Analysis Considering Manufacturing Error

机构误差分析方法缺乏通用性,无法形成计算机辅助误差分析软件。虽然计算机辅助结构件误差分析已经形成商业软件,但机构中包含相对运动,误差因素更复杂,因此结构误差分析软件不能直接用于机构误差分析。文中提出了一种嵌套的误差传递矩阵,用以描述机构误差源至末端通路上的误差传递情况,进而提高机构误差分析方法的通用性和自动化程度。

Computer-aided mechanical error analysis is not available because the method is not universal. Business softwares used in computer-aided structure error analysis can not be used in mechanical error analysis directly due to more complex error sources in mechanism. In this paper, a nested error transfer matrix is proposed to describe the error transmission in the mechanical system, so that the generality and automatic degree can be improved.
