关 键 词：ISD suspension mass change vibration response coupled vibration
摘 要：In order to study the influences of mass variation on vibration response characteristics of ISD suspension,the ISD suspension composed of four elements is *** acceleration,suspension travel and dynamic tire load as the assessment criteria are studied in the time and frequency domain simulation with sprung and unsprung mass increased and decreased by 50%,*** results show that the root mean square（RMS） of body acceleration reduces and the RMS of suspension deflection increases with the increase of the sprung *** RMS of dynamic load increases with the increase of unsprung *** the low frequency（0～5 Hz）,the peak value of low frequency resonance of suspension dynamic travel and dynamic tire load increases *** the high frequency（5～15 Hz）,the resonant frequency decreases and amplitude increases with the increase of the unsprung *** with the traditional passive suspension,when the sprung mass is increased by 50%,the RMS of body acceleration,suspension dynamic travel and dynamic tire load are decreased by 6.92%,4.48%and 4.02%,*** the unsprung mass is increased by 50%,three factors are decreased by 6.31%,20.32%and 5.96%,*** indicates that ISD suspension possesses better ride comfort and handling stability when the mass varies due to the coupled vibration effect of inerter.
