Research on Vehicle Comfort under Two Axis Vehicle Excitation
In recent years,the issue of vehicle comfort caused by vehicle bridge coupling vibration cannot be ignored.Taking a two axle vehicle as an example,based on the ISO2631 method,the weighted root mean square value of acceleration is used as the evaluation index to study the changes in vehicle comfort under different bridge surface roughness and vehicle weight.The results show that as the condition of the bridge deck deteriorates,the root mean square value of the vehicle's weighted acceleration significantly increases;When the vehicle weight is gradually loaded from 30%to 110%,the root mean square value of the vehicle's weighted acceleration gradually decreases,and its research results provide a certain reference for the comfort analysis of vehicles.
