In order to achieve improving both performance of curve-passing and critical speed of hunting motion for railway vehicles, the assist steering system that builds the actuator function into mono-link type primary suspension has been developed. As a result of the running test, outer side lateral force of the leading axle in a circular curve section was decreased by about 30% by adoption of the developed system. However, the running test results on the test track remained different from those on a typical commercial line because of the restriction of the alignment of the test track and the test vehicle's performance. Therefore, quantitative examinations of the lateral force reducing performance in high speed running situation, and the influences of the lateral force increase on inverse steering condition were carried out with the bench test device that is able to simulate the running condition in a circular curve section of the commercial line. In the bench test, this system could achieve 70 to 90% decrease of the turning lateral force compared with the passive condition. It has been recognized that the turning lateral force would not be affected by the radius of the curve section and vehicle's running speed, but be affected only by the geometrical factor. Moreover, the mechanical reverse-steering prevention strategy that was established based on the characteristic of the assist actuator's inner structure and the longitudinal creep force was studied. In addition, the authors report the stability confirmation of bogie hunting motion during operation of the assist actuators.
