Abstract
This paper established a lateral stiffness coupling model to investigate the lateral characteristics of air spring system under crosswind conditions. The nonlinear super-elastic characteristics, coupling characteristics of the air spring, lateral stiffness characteristics of emergency spring, and damping force are studied. The accuracy of the lateral stiffness model is validated by comparing with experimental data. In addition, the impact of geometric parameters on the lateral stiffness characteristics is discussed by a sensitivity analysis method, as well as the effect of the lateral stiffness model on vehicle mechanical performance is analyzed. The conclusions show that the lateral stiffness model can well predict the lateral characteristics of the air spring system, and provide theoretical guidance for the parameter design of rail vehicles and vehicle ride comfort improvement.
Highlights
IntroductionWhen railway vehicles encounter strong crosswind or curve, a harmful lateral vibration and car-bodyswaying phenomenon will occur.[3] The lateral stiffness and damping characteristics of air springs can effectively attenuate the harmful vibrations and provide better ride comfort of railway vehicles
With the increase in the vehicle speed and the lightweight of vehicle design, the risk of vehicle derailment or rollover under the influence of crosswind has become a non-negligible problem.[1]
The lateral characteristics of air spring system in the presence of crosswind is investigated by establishing a lateral stiffness model and a damping model
Summary
When railway vehicles encounter strong crosswind or curve, a harmful lateral vibration and car-bodyswaying phenomenon will occur.[3] The lateral stiffness and damping characteristics of air springs can effectively attenuate the harmful vibrations and provide better ride comfort of railway vehicles. The lateral stiffness and damping characteristics of air spring system are the focus of this article
