Abstract
In order to improve the ride comfort, reducing lateral acceleration is necessary. This paper treats the railway vehicle which runs in curved sections. As a determination method of tilting control quantity operated at present, there are two kind of methods. One is the system using in Japan. It has curve data of the travel interval in the on-board, and it is a method for the tilting order according to the position signal detected from the ground. Another is the system mainly used in Europe, and curve information should not be used, and over centrifugal acceleration which affects the car body is obtained from lateral acceleration in not tilting car truck division, and the tilting quantity has been deduced. The basis of the tilting control method for realizing the inclination goal is also the feedforward tilting control on both systems. In this paper, the feedback type of tilting control, which can maintain the vehicle inclination close to a desired value, is examined ; reduction of vehicle body vibration is also expected with this control. Practically, the curves are obtained by collecting data in real time from the vehicle body traveling through a curve, and this information is utilized in the proposed tilting control method. The effects of the control system are verified by computer simulation study and experiment study.
