D703 HIGH SPEED RUNNING TEST AND THE NEW TESTING EQUIPMENT FOR WHEEL/RAIL DYNAMIC INTERACTION

抄録

Effects of unsprung-mass of vehicle wheel load variation and ground vibration become more important as train speed increases especially for high speed railway. Those have been examined through high speed running test with an experimental train. Rail roughness and wheel rotation-vibration were identified as the major factors of wheel load variation. Then the new testing equipment is introduced to study on wheel/rail dynamic problem in more detail.
