Railway truck is necessary to have excellent curving performance as well as high speed hunting stability, but generally they are contrary to each other. "Active-bogie-steering (ABS) truck", is one of the methods to realize the compatibility between curving performance and hunting stability. ABS truck has active steering mechanism only between car body and truck frame, and truck flame is steered by actuators toward "radial steering position", which realizes no "bogie angle shortage". Validity tests were carried out on the truck rolling test stand, and we have also carried out numerical simulation using multi-body dynamics simulation program A'GEM. The results of stand tests and numerical simulations show that "bogie angle shortage" is reduced proportionally by bogie-steering actuator force, therefore active-bogie-steering can remarkably reduce the lateral contact force of the outside wheel of leading axle even in sharp curve.
