STUDY ON THE PERFORMANCE OF NTS VEHICLE STEERING CONTROL SYSTEM

An automated guideway transit system is under construction in Osaka City, Japan. Initial operation is planned for 1981. Performance of the vehicle steering control system is considered. Clearance is intentionally provided between guide wheels and the guide-wall to reduce lateral disturbance of the guide wheels caused by guideway irregularities. A mathematical model is derived for the lateral motion of the vehicle with its front and rear steering linkages interconnected by a rod. The effects of some design parameters of the steering system on the lateral motion of the vehicle are predicted by use of computer. The lateral motion of the vehicle is observed after an ideal disturbance force at the front edge of the vehicle-body for one second. It is found that though, in general, the clearance between guide wheels and guide-wall reduces steering control stability and causes oscillatory lateral motion, the connecting rod between the front and rear steering linkages restrains the oscillatory lateral motion, when the steering control gains of front and rear are chosen appropriately.
