Abstract

This paper investigates the energy consumption of the lateral secondary active suspension for railway vehicles and studies the conditions for self-powered active suspension control. The influence of the performance index weighting factors to both the ride quality and the energy consumption is discussed based on the linear quadratic regulator (LQR) algorithm. Then the energy balance condition is analyzed. With low energy harvesting restriction, the self-powered condition can be achieved. At last, simulation results are provided to validate the feasibility of the self-powered suspension.
