摘　　要：为了对用于摩擦磨损试验机的测力传感器进行静态标定,对其进行加载、卸载试验,根据最小二乘原理,分别采用Matlab和Origin 2种功能强大的数据分析软件对试验数据进行线性回归运算得到测力传感器输入—输出数学模型和灵敏度、非线性误差等静态标定指标。结果表明:2种软件标定结果十分接近,且具有各自的特点。To calibrate the force sensor used in the friction and wear tester in static state ,loading and unloading experiment are made. And then according to the least squares principle, two powerful data analysis softwares, Matlab and Origin are adopted, for test data＇ s linear regression and computation to get the input and output mathematical model and static calibration indexes of the force sensor, such as sensitivity, nonlinear error and so ott, The experiment results show that two softwares calibration results are close to each other and they also have their own eharaeteristics.
