Self-Powered Active Lateral Secondary Suspension for Railway Vehicles

Design of a Tubular Permanent Magnet Actuator for Active Lateral Secondary Suspension of a Railway Vehicle

This paper describes the finite element (FE)-based design of a slotted tubular permanent magnet actuator (TPMA) used in railway vehicle active lateral secondary suspension that improves the actuator’s thrust and lowers its cogging force under thermal and geometric constraints. To consider the electromagnetic and thermal fields and the complex interactions among the design variables, design was ...

Active Suspension System in Parallel Hybrid Electric Vehicles

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

Control for Railway Vehicles

Active Steering of Railway Vehicles via Dobc Techniques

A novel control scheme for the active steering of railway vehicles is presented in the paper using disturbance observer based control (DOBC) techniques. In contrast to existing DOBC schemes which are mainly for singleinput-single-output (SISO) systems and designed by trial and error, a new DOBC technique for multi-input-multi-output (MIMO) systems is developed. This is achieved by reforming the...
