Abstract
This paper presents a method to analyze the mechanical environment of non-stationary random excitation process of industrial robots.In this method, the non-stationary stochastic process is represented by several slow-varying uniformly modulated stochastic processes so that the analysis process is greatly simplified.The demodulation method is used to analyze the vibration signal of an industrial robot, the characteristics of vibration excitation load can be evaluated, and interference samples can be provided for the control system of industrial robot, so as to improve the control precision of the robot.
