Methodology for the vibration measurement and evaluation on the industrial robot Kuka

The aim of this paper is to point out the need of applying the proactive and predictive maintenance as the key instrument for the maximum operational reliability and usability of the industrial robots using the minimum costs and human resources. We want to emphasize that by the vibrodiagnostics method, which is one of the methods for ensuring the operability of the robot, extended life of the industrial robots and energy savings will be reached. The vibration measurements had been realized using the three accelerometers. Their evaluation was done via computer software ScopeWin. FFT transformation was applied for analysis of the spectrum of vibration. The purpose of the paper lies in proposing a comprehensive methodology for the measurement and evaluation of vibration on the industrial robot, and serves as a way to obtain additional recommendations and drafts of the procedures for maintenance and fault diagnosis of the industrial robots.
