The Nonlinearity Correction of the Posture Measurement System for the Thread Measuring Front

  • 摘要: 螺纹测端姿态测量是数字化轮廓包络法螺纹综合测量的关键技术之一。设计了基于AD598的螺纹测端姿态测量系统。为了提高螺纹测端姿态测量的精度,需要对螺纹测端姿态测量系统的非线性进行矫正。通过对信号采集系统的传递函数进行标定,将传递函数的线性部分和非线性部分进行分离,通过求解非线性部分的转换函数,在软件算法中实现了非线性部分的矫正。实验结果表明,非线性矫正后螺纹测端姿态测量系统的转角测量非线性误差减小1'17.25″,将测量系统的非线性误差控制在0.12%内,满足了测量系统的要求。
