基于传递路径分析的激励对汽车平顺性的影响
Influence of Excitation on Vehicle Ride Comfort Based on Transfer Path Analysis
摘要
Abstract
In order to explore the influence of the engine excitation and the road excitation on the ride comfort for vehicle,a full vehicle model with 13 freedom degrees containing the mounting system and the suspension system was established,and the engine excitation and the road excitation were introduced. The method of the ride comfort for vehicle based on TPA was derived. On the basis of the simulation calculating,the road test of actual vehicle was conducted. The results of simulation calculating and experiment result were consistent,which proved the correctness of this model. Based on the corresponding relationship between vehicle speed and engine speed in different gears,the ride comfort for vehicle under different excitation was analyzed. The results indicate that the influence of the road excitation is less than the engine excitation on the ride comfort for vehicle,but its influence cannot be ignored.关键词
