Frequency-domain Modelling and Simulation of a Vehicle Fitted with Kinetic Dynamic Suspension System
摘要
Abstract
This paper took an SUV vehicle as the prototype,established a frequency-domain model of vehicle with KDSS-fitted,based on the transfer matrix method to derive the impedance matrix of hydraulic subsystem,solved the eigenvalue in numerical optimization iteration method,compared and analyzed the modal parameters of KDSS-fitted vehicle,ARB-fitted vehicle and no-ARB-fitted vehicle model.The results indicate that KDSS is able to effectively reduce the roll motion of sprung mass in the same way as anti-roll bar,and simultaneously maintain the ride comfort performance.At the same time,the wheel torsion stiff-ness,compared with ARB,is greatly reduced.This gives the wheels full contact with the ground and im-proves the passing ability of the vehicle.关键词
