A Study on the Quasi-static Overturning and Derailment Safety of Tilting Train

Recently, the speed of a train has been increased. So the trains are being exposed to wind more severely than before. Because of the operation of high speed trains and lightweight of the train, risks of train derailment have being increased. In this study, aerodynamic effects of a newly designed high speed train, HEMU-400x, are evaluated. For aerodynamic effect evaluation, analysis method is selected by examining the safety standards for high speed train. The condition of aerodynamic effects

Abstract:In this paper we deal with a hydraulic tilting actuator to make a diagnosis of load characteristic acting on the tilting actuator of the tilting train. Tilting actuator in the tilting train plays a role of making tilt of the train when the train runs a curve section to make the train run without deceleration. However in the process of tilt the tilting actuator is affected by the load acting on the actuator, which has a possibility to make bogie vibration. In order to figure out the effect of the load on the tilting actuator a hydraulic tilting devices that are capable of tilting the train is proposed. The proposed devices are installed in the front bogie and in the rear bogie to make tilting of the train. The devices are consist of sensors that measure the load capacity of the actuator and displacement of the hydraulic cylinder stroke, control blocks to make synchronization of the two actuators, user interface block to monitor the status of the actuators. The effectiveness of the proposed hydraulic tilting actuators is presented by the experimental evaluation using actual tilting train.
