机械装置综合误差分析及计算

Analysis and Calculation of the Synthetical Error in A Maching Structure

本文把机械装置中每个零件的位置、姿态、位移误差和转角误差在三维空间中用矢量和矩阵来表示．运用三维空间坐标系的转换，通过矢量和矩阵的运算，建立了机械装置综合误差计算的数学模型，并提出了简便实用的计算方法通过减速器综合误差的实例计算，得到了满意的结果．

The place, Pose, displacement errror and rotating allgle ermr of every parts in the machinestructure are expressed by means of vector and matrixin a three dimension (3-D) space in this paper.The mathematical model of the synthetical error calculation is established by transformation of 3-Dcoordinate system and vector and matrix operations. A conveniellt and practical calculation methodis given. The satisfied result is obtained by the calculation of a engineering example of the syntheticalermr in a decelerator.
