Nowadays, the more speedy and functional railway vehicles are required by customers, the more broad boundary conitions of train's running are present. At this condtion, it is difficult for the traditional concept of suspension system which has the constant characteristics dependant on the running condition to meet the advenced requirements such as high ride quality. So, the active suspension should be designed to supplied the optimized suspensnion condition actively and to perform the optimal ride quality on the irregula running condition such as on the enterance or exitance of the tunnel or on the crossing the high speed train each others. On this study, the train dynamic model, integration of active suspension system, and the control logic would be proposed, and the advanced performace of train would be shown though the simulation tests.
