摘要
该文在分析液压 CAT 系统被测信号传递过程的基础上,应用多项式最小二乘法建立被标定测量系统的静特性数学模型。用非线性方程补偿、校正测量系统的非线性特性。最后根据 ISO 标准和新国标的要求提出划分被标定液压 CAT 系统精度等级的方法。
The calibration of fluid power transmission computer aided test syste-ms is a complicated and important problem.This paper presents a mathmatical model of static characteristics forcalibrated systems.By means of nonlinear equation compensate nonlinearerror of tested systems.According to ISO requirement and new state requirement,a method ofprecision division for fluid power transmission CAT systems is presen-ted.
