【摘要】：为了提高ABS齿圈检测仪测量质量,根据ABS齿圈检测仪测量原理、结构特点及测量过程中产生误差的原因,综合分析了影响ABS齿圈检测仪测量精度的本质因素,针对产生误差的关键问题,开发了一种以空间三维直角坐标系仿射变换原理及最小二乘法曲线拟合原理为核心的实时误差校正方法,该方法可在不降低测量速度的前提下,进行自适应实时误差校正,提高测量精度。同时,根据误差校正原理建立了数学模型,并通过MATLAB 7.10仿真验证了其准确性及可行性。经计算,误差校正后的ABS齿圈检测仪测量重复性和不确定度指标符合预期要求。事实证明该方法能够用于ABS齿圈检测仪系统中,具有很高的实用价值。
[Abstract]:In order to improve the measuring quality of ABS gear ring detector, according to the measuring principle, structure characteristics and the cause of error in the measurement process, the essential factors influencing the measuring accuracy of ABS gear ring detector are analyzed synthetically. Aiming at the key problem of generating errors, a real-time error correction method based on the principle of affine transformation in three-dimensional rectangular coordinate system and the fitting principle of least square curve is developed. Self-adaptive real-time error correction is carried out to improve measurement accuracy. At the same time, the mathematical model is established according to the principle of error correction, and its accuracy and feasibility are verified by MATLAB 7.10 simulation. After calculation, the measurement repeatability and uncertainty of ABS gear ring detector after error correction are in line with the expected requirements. It has been proved that this method can be used in ABS gear ring detector system and has high practical value.
