三大件货车转向架载荷敏感阻尼的试验和理论研究

Experimental and Theoretical Investigation into Load Sensitive Damping in Three Piece Freight Car Bogie

介绍南非三大件货车转向架载荷敏感阻尼（即变摩擦阻尼）的最新研究。其目的是了解这种非线性悬挂元件的性能，并预测由于车辆在非理想轨道上运行，车辆／轨道系统的性能及其性能恶化。

This paper reports on recent investigations done in South Africa with respect to load sensitive damping in three piece freight car bogies.The objective was to understand the behaviour of this nonlinear suspension element and to predict the performance and the degradation of the vehicle/track system as the vehicle travels over non ideal track.
