The Research of Vehicle Seat Dynamic Comfort Characteristic
Increasing consumption of the automobile make vehicle seat comfort characteristic paid more attention to.Damping performance as the third important factors is not allowed to ignore.A three freedom human-seat system model has been created for simulation.The result show that as the natural frequency f0 improved,the two resonance peak frequency of the system also improved,the growth of the first order resonance frequency is quite obvious,the second is less growth.And the higher the f0 the less change is.With the improvement of f0,the first order resonance peakto peak value obviously reduced,and the second order resonance peak to peak value increased.So,it is said that the higher the f0 the poor damping effect in high frequency area.The influence of ξ for the damping ratio of work frequency is not big,but the influence for the amplitude value is significant.Increase the natural frequency can make phase angle decreased when resonance,but the change of damping ratio,do not have obviously changes.
