Effect of Structural Parameters on Dynamic Characteristics of Air Suspension Supply System
To reduce the overshoot and adjustment time of the air suspension system in height adjustment of a passenger car,an open-loop air suspension supply system model is constructed using AMESim software to simulate the rising process of the car body.The overshoot and adjustment time of the car body height adjustment are taken as evaluation indicators.An L16(45)orthogonal experiment is designed to study the influence of gas storage tank pressure,electromagnetic valve spool diameter,pipe inner diameter and shock absorber damping coefficient on the performance of the air suspension supply system.The results show that each structural parameter has different degrees of influence on different evaluation indicators of the air suspension supply system.The shock absorber damping coefficient has the greatest impact on the overshoot of the car body height adjustment.The gas storage tank pressure has the greatest impact on the adjustment time of the car body height adjustment.The research results provide reference value for the selection of structural parameters of the air suspension supply system.Through optimization design of the structural parameters,the overshoot of the car body height is reduced by 35.24％,and the adjustment time of the car body height is reduced by 38.51％,resulting in a significant improvement in the performance of the air suspension supply system.
