A402 The Study on Control of Air Suspensions for Rail Vehicles Considering Tight Curving Performance : Experiments and Simulation Using The One-car-modeled Test Bench

抄録

This paper presents the curving performance of rail vehicles with air suspensions. Air suspensions sometimes cause reduction of wheel load at transition curve at low speed, so it is very important to evaluate the performance on transition curve. The air suspensions have non-linear characteristics, consequently that the performance might be influenced by the initial condition, the entrance transition curve condition and so on. In this study, the effects of track and running condition on curving performance at the transition curve section were examined by computer simulations and experiments using the full scaled one-car-modeled test bench. It was found that that the performance was influenced by the air flow through the levering valve into or out the air suspensions and the experimental results agrees with computer simulations. So it is effective to consider the characteristics of air suspension system to improve safety of running.
