Dynamic Simulation of Rapid Transit Vehicle Shyh-Chour Huang Department of Mechanical Engineering National Kaohsiung University of Applied Sciences Kaohsiung, Taiwan 807 Republic of China Ren-Sheng Lin Kaohsiung Mass Rapid Transit Kaohsiung, Taiwan 808 Republic of China and Yung-Chuan Chen Department of Vehicle Engineering National Pingtung University of Science and Technology Pingtung, Taiwan 912 Republic of China Abstract The mass transit system is the most common solution of urban traffic problem around the world. It is constructed to alleviate congested highways and to provide the efficient mass transportation. One of the critical design issues in construction mass transit system in the tunnel is that the tunnel section is the interface of rail vehicle and tunnel. The analysis of Kinematic Vehicle Gauge (KVG) is to determine the cut of cross section area and the arrangement of facility in the tunnel. The KVG must be feasible, if not, the cost of construction is over-budget and the ride quality of passengers is sacrificed, and the collision of rail vehicle and tunnel or the rail vehicle and platform occurs as well. The objective of this paper is to present modeling and simulation of the dynamic response of the rail vehicle when it subjected to road roughness excitation.

Introduction Platform gap is one of the design factors of designing mass transit system. Construction company will design the platform in accordance with this factor. The design engineer of train suspension system also will use this platform gap to design the system. For a mass transit system, the duration of the train in the platform is about 20 to 25 seconds.
