Actual-measurement beat data-based typical rotary part representation method

The invention provides an actual-measurement beat data-based typical rotary part representation method. Aiming at rotary part representation comprising morphology data, a matrix form representation method comprehensively considering micro beat data and macro axial size is proposed. Moreover, the method can be applied to the assembly accuracy calculation process, a single part comprising morphologycharacteristic quantity can be represented only by a matrix M, the accuracy transfer calculation process is simplified, and a high-efficiency calculation model is provided for assembly accuracy forecast. 本发明提供了一种基于实测跳动数据的典型回转体零件表征方法，针对包含形貌数据的回转体零件表征，提出了一种综合考虑微观跳动数据和宏观轴向尺寸的矩阵形式表征方法，另外该方法可以应用到装配精度计算过程中，仅采用一个矩阵M即可表征包含形貌特征量的单个零件，简化了精度传递的计算过程，为装配精度的预测提供了一种高效计算模型。
