摘　　要：为了提高航发叶片坐标测量系统的检测精度,采用多体系统运动学的理论分析方法,利用齐次方程转换坐标系,结合运动链之间的变换关系,建立叶片测量机构空间定位误差综合模型。用高精度激光干涉仪检测并标定测量机的几何误差,采用非实时误差补偿方法修正叶片型面的测量数据,达到抑制系统误差和提高叶片型面测量精度的目的。In order to improve the detection accuracy of aeroengine blade coordinate measurement system,the theoretical analysis method of multi-body system kinematics is adopted,the coordinate system is transformed by homogeneous equation,and the spatial positioning error comprehensive model of blade measurement mechanism is established in combination with the transformation relationship between motion chains.The geometric error of the measuring machine is detected and calibrated with a high-precision laser interferometer,and then the measurement data of the blade surface is corrected.The non-real-time error compensation method is adopted to reduce the system error and improve the measurement accuracy of the blade surface.
