Friction Torque Measurement of Servo Mount Based on Stribeck Model

Abstract:

In this paper, in order to realize mechanical behavior analysis and friction disturbance accurate compensation. A measurement system of friction with accelerometer is designed. Principle and method of friction measurement are analyzed, and the system is built. The torque ripple has a huge impact on friction measurement. The digital filter is designed for filtering error which is caused by toque ripple, and the virtual value of friction torque can be acquired. The parameter of friction torque can be obtained using nonlinear least squares method. The experiment is carried out on the servo mount. This measurement system and method can effectively and accurately measure friction torque of servo mount, and be used in measurement of friction torque on other mount.
