Abstract:
In order to study the influence of velocity change on vehicle ride comfort, taking the influence of longitudinal inertia force and time-variant white noise frequency from vehicle velocity change into account, a suspension dynamic model of 1/2 vehicle was established with road random inputs. The time-variant white noise frequency model was obtained by using the Lookup Table Module in the Matlab/Simulink Software with road by the real-time vehicle speed. The results show that velocity change makes the index of suspension deflection become worse obviously but has no influence on the indexes of tire deflection, sprung mass acceleration and body pitching angle acceleration. The bigger the change of vehicle speed and the less the suspension stiffness, the more obvious the phenomena above. When the height of mass centre is decreased by 20% and the stiffnesses of all springs are increased by 10%, the vertical and pinching acceleration indexes increase by 6.96% and 0.89% respectively, and the front and rear suspension deflection indexes decrease by 20% and 17.6% respectively. 5 tabs, 10 figs, 18 refs.
