Self-powered active lateral suspension for railway vehicles

Abstract

This paper presents a design methodology for the development of self-powered active lateral secondary suspensions for rail vehicles. It firstly investigates the energy flows in the active lateral secondary suspensions and analyzes the conditions for self-powered control in detail. The impact of the controller design on both the ride quality and the energy consumption is then used to guide the design/specification of actuators and to define key actuator parameters in order to achieve both expected performance improvement and zero-energy consumption for the actuators. Furthermore, a control strategy for dealing with larger than expected energy consumptions by the active suspensions is proposed to eliminate excessive power requirements, but also to ensure the ride quality improvement in comparison to that of passive suspensions. Computer simulations are used to validate the control strategy for the self-powered active suspension.
