基于垂向载荷转移率的微型客车侧倾敏感性研究
Study of Light Vehicle Rollover Tendency Based on Vertical-Load Transfer Rate
摘要
Abstract
Taking a mini-bus as the research object,a three degree freedom multi-body dynamics model is developed using Matlab/Simulink to analyze mini-bus dynamics and sharp turn stability.Using the J-turn and NHTSA Fish-hook virtual tests,the influence of vehicle velocity and steering angle on the vehicle lateral acceleration and vehicle body rollover angle are analyzed.The influences of mini-bus structure,traffic conditions,and external conditions on the rollover tendency were also analyzed in single-factor experiments.A correlation between the vehicle parameter of center of gravity location and rollover propensity is found,and the results show that the vehicle center of gravity is the most important parameter which influenced the rollover tendency of mini-bus,and combined of the vehicle velocity,the steering velocity also has some influence on the rollover stability of mini-bus.The results can be used to improve mini-bus redesigns,to improve risk prediction,and to reduce the incidence of traffic accidents.关键词
