Damping Characteristics of an Inter-vehicle Damper and Its Influence on High-speed Train Dynamics
摘要
Abstract
It is meaningful to improve high-speed train operating dynamics by optimizing its inter-vehicle suspension and core component.Parametric modelling of an inter-vehicle damper was carried out by analyzing its shim-pack valve system with pressure-flow characteristics,the obtained parametric model then was validated by comparing simulation result with product experiment result.A multi-body system dynamic model was developed for the high-speed train in the SIMPACK environment,the effect of damping characteristics of the inter-vehicle damper on train dynamics including that when two high-speed trains pass each other was performed,simulation results show that inter-vehicle damper can obviously attenuate the complex lateral vibrations and improve ride comfort,it can significantly suppress the large complex lateral oscillations,particularly the roll motion,during two trains passing each other,in addition,it can decrease the wheelset lateral shift force and derailment coefficient,thus improve integrity and safety of the train.The obtained mathematical parametric damper model,high-speed train multi-body system model and research results would be useful for further optimal specification and product optimization of the inter-vehicle damper.关键词
