摘要
本文以某款大排量两轮摩托车为研究对象,针对大排量摩托车在高速工况下操纵稳定性问题,使用多体动力学仿真软件VI-Motorcycle,对其在高速直线工况下行驶受扰时的稳定性进行仿真实验,并利用根轨迹检验方法对结果进行分析。结果分析表明:大排量两轮摩托车在高速工况下,车辆受到微小瞬态扰动力矩时将会发生抖动(wobble)和摇摆(weave)现象,影响大排量两轮摩托车高速行驶时的操纵性能以及车辆的稳定性,结果验证与根轨迹法分析一致。本论文仿真结论对以后国内大排量摩托车操纵稳定性的研究有一定的参考价值。
This paper takes a large-displacement two-wheeled motorcycle as the research object,aiming at the handling stability of large-displacement motorcycle under high-speed working conditions,the multi-body dynamics simulation software VI-Motorcycle is used to analyze a large-displacement two-wheeled.A simulation experiment of the stability of a largedisplacement two-wheeled motorcycle when disturbed under high-speed linear working conditions,and the results were analyzed by using the root locus test method.Analysis of the results showed that:In high-speed conditions,large-displacement two-wheeled motorcycles will have wobble and weave phenomena when the vehicle is subjected to small transient disturbance moments.It affects the handling performance and vehicle stability of largedisplacement two-wheeled motorcycles in the high speeds,and the results are verified to be consistent with the analysis of the root locus method.The simulation conclusion of this thesis has a certain reference value for the future research on the handling stability of domestic large-displacement motorcycles.
