Abstract

This article proposes an inertial force calibration method based on correction factors, which can improve the accuracy of correcting inertial forces. Through experiments, taking the calibration of the cyclic force of a certain model of 500kN electromagnetic resonance fatigue testing machine as an example, the calibration results of the cyclic force, the amplitude frequency characteristics of the force sensor, and the correction of the inertial force were analyzed and the uncertainty was evaluated.
