Source:   Author:     Time:2020/12/22 00:45:43   Hits:  



This system consists of four parts: mechanical, hydraulic, servo control and data acquisition Systems. The hydraulic power units are shared with the carbody fatigue test bench.


Functions:

Static and dynamic loads are applied onto the bogie frame by the rig to verify the strength under normal and extreme operating condition cases. Random loads can be generated by the iteration method embedded in the servo control system to verify the reliability of the bogie frame under real operating conditions. Other components such as bolsters, axle boxes can also be tested by this rig.
