| Abstract: | According to fatigue life test regulation and functions of a front axle, the paper describes the installation of samples, exertion of force and the design trait of electro hydraulic servo controlled machinery with an alternating and leaning load. Transmitting load by Ibeam with smaller mass and larger strength, the anti resonant frequency of loaded body is much higher than stipulative test frequency, which produces the desired effects for PID correction of the system. After analyzing and measuring dynamic features of the system a good result was obtained by means of correction and compensation. |
