Abstract:
This paper presents a novel application of hydraulic electromagnetic energy-regenerative shock absorber (HESA) into bogie system of railway vehicles. In order to find out the relationship and differences between first suspension system and second suspension system when installed it, HESA is built in AMESim to make comparison studies on the different department suspensions caused by the nonlinear damping behaviors of the HESA. The simulation results show that the system can effectively reduce the impact between wheel and rail tracks, while maintaining good potential to recycle vibratory energy. And the relationships as well as differences between the first suspensions and second suspensions have been concluded, which are useful for the design of HESA-Bogie. Moreover, comparing the discrepancy between the first suspension system and second suspension system, the potential of energy harvesting of the bogie system which installed HESA can be evaluated and then the best application department can be found, which proves the theoretical feasibilities of the HESA-Bogie of this structure to reduce the fuel economy.
