Abstract

In order to obtain the kinematic error and clearance in harmonic drive, an experimental setup was established. The cause of beat frequency characteristic was analyzed and verified by the FFT result of experiment data. The position dependent kinematic error was modeled by Fourier expression method and the simulated model was also verified by another set of experimental data. And a reversing experiment was designed to acquire the change process of clearance in harmonic drive and the frequency domain method was applied to extract the clearance value. The proposed measurement and modeling method will be useful to the dynamic modeling and performance evaluation of harmonic drive.
