Design and Simulation of the Hydraulic Loading Control System of the Rolling Bearing Fatigue Life Testing Machine

Abstract:

With the continuous expansion of China's bearing industry, rolling bearing life testing machine is becoming increasingly important in the enterprises. Due to its high cost and the complexity of controlling, it is relatively difficult to develop them. Therefore in the medium and small enterprises they are seldom used. In the present study we improve the hydraulic loading control system of the ABLT-5A rolling bearing life testing machine. In addition, we apply mathematical modeling for the control system and simulation analysis by MatLab software, in order to spread and promote the rolling bearing life testing machine in the medium and small enterprises, especially to conduct corresponding researches on the control precision and stability of the hydraulic loading control system.
