汽车起步颤振动力学问题研究综述

A Review of Research on Start-up Judder of Vehicles

摘要:

归纳总结了汽车起步颤振动力学问题的研究现状和发展趋势。首先，以整车动力传动系统模型作为问题现象再现的仿真平台，着重论述与起步工况密切相关的部件，包括离合器操纵特性、摩擦特性和发动机瞬态扭矩等。然后，针对汽车起步颤振问题，从试验研究、产生机理、抑制措施3个方面讨论了起步颤振动力学问题研究内容和方法。最后，在已有研究成果及其不足的基础上，指出了汽车起步颤振问题的研究重点和难点，为进一步研究提供参考和建议。

Abstract:

This paper discussed the research status and development trend of the dynamical problem of start-up judder of vehicles. First， the transmission system model of vehicles was used as a simulation platform to reproduce the problem， which focuses on the components closely related to the start-up conditions， including clutch operating characteristics， friction characteristics， and engine models. Then， in view of the start-up judder， the research contents and methods of start-up judder mechanics were discussed from the perspective of experimental research， generation mechanism， and suppression measures. Finally， based on the existing research results and their deficiencies， the focuses and difficulties of the research on start-up judder were pointed out， which provides references and suggestions for further research.
