Paper Title:
Application with Theory of Vibration Equivalence on Reliability Test Bed of Train Brake System
  Abstract

In order to design a reliability test bed for train brake system, theory of vibration equivalence was used to represent in laboratory the environmental vibration. Firstly, the root mean square (RMS) value of the acceleration was calculated for train brake system according to IEC 61373. Then, a configuration of vibrostand was proposed for the reliability test bed, which was mainly composed of vibrating table-board, vibrator motor, damp and four vibrating springs, as shown in figure 2. After that, an equation was got according to the RMS equivalency theory. Finally, the equation was solved according to the feature of the vibrostand. And the quantitative relation was got for exciting force F0, shock excitation circular frequency ω and spring rate k. The method can also be used on other occasions where sinusoidal vibration is needed to replace random vibration.
