车辆过渡工况基础研究

随着节能和环保要求的不断提高，车辆轴系在过渡工况下的扭振动态特征日益受到关注，但目前过渡工况下的轴系扭振少有定量分析。针对这一情况，本文建立了过渡工况轴系扭振基础研究模型，并根据各种典型过渡工况轴系激振力矩幅值、频率特性，进行了过渡工况轴系扭振特性的基础研究，从而得出了轴系在过渡工况的一些规律。

Foundation Research on Transition Working Conditions of Vehicle

Mong with the increasing demands of energy saving and environmental protection, the dynamical properties in transient conditions of the shafts of vehicles are got much attractive, however, there is little quantitative analysis on the working processes of shafts in transient conditions. In terms of this circumstances, the foundation research model for the torsion vibration on shafts in transient conditions was set up in this paper, and based on the characteristic of amplitude, frequency and phase of the excited moment on shafts on each kind of typical transient conditions, the researches of the characteristics of the torsion vibration on shafts in all transient conditions were carried through, and received the common property of the shafts in transient conditions.
