A study on the Dynamic Performance of 200km/h Korean Tilting Train by means of Roller Rig Test

초록

The various dynamic performances of newly developed railway vehicle should be carefully verified step by step, from computer simulation through the laboratory based roller rig test to the main line trial running test. The laboratory based roller rig test is the effective and safe way to evaluate the dynamic characteristics such as high speed stability impossible in the main line, ride comfort, dynamic behaviors. This experimental research was performed to evaluate the various dynamic performances of 200 km/h Korean tilting train, ‘Hanvit200’, by means of full scale roller rig test. The newly developed tilting mechanism and stabilizing mechanism was included in the Tilting Bogie to satisfy the both conflicting requirements higher stability and higher curving performance. This paper shows the Roller rig test results and the effectiveness of Tilting Bogie design. This paper include the roller rig test results of various kinds of conditions such as tare and fully laden load case, normal and failed case of important bogie components, linear and non-linear critical speed.
