Study on the control system of urban rail vehicle air spring test bed

摘要

According to the various forms of air spring system maintenance needs in urban rail vehicles, the multifunctional air spring performance test bed is designed and developed. Firstly the transmission and control system mathematical model of test bed are established, and the fuzzy control algorithm is introduced to the control system design. The experiments are carried out to verify the system simulation by using test bed. The fuzzy control method can effectively improve the precision and stability of the control system, which further ensure the accuracy of performance test in the experiment results.
