A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

The relation between electrokinetic potential and suspension stability of four strains of non-flagellate intestinal bacteria has been studied. The smooth forms have zeta-potentials which approximate zero over a wide range of pH and salt concentration, yet nevertheless form stable suspensions. The rough variants have zeta-potentials which vary with pH and electrolyte concentration in the familia...

In the vehicle development, the importance of reducing road noise is increasing because of the increasing popularity of quiet electric vehicle. The suspension plays an important role on the mechanism of the structure born road noise. As the countermeasure for reducing road noise, low stiffness suspension bush is often used from the point of view of vibration insulation. However, in general, to ...

For a singularly perturbed magnetic suspension system, two kinds of state feedback controllers are synthesized to account for the inherent instability of the open-loop plant with two-time-scale properties. Kharitonov polynomials, extremal vertex and uncertain Nyquist plot are employed to examine the maximum tolerance against system parameters uncertainties such that the stability of the closed-...

In this work, suspension characterization of a rapid transit vehicle is performed with a multi-body dynamic model that represents full degrees of freedom of a rapid transit vehicle. The effects of lateral suspension properties on passenger ride comfort and stability are investigated by variation of critical suspension parameters using design of experiment method. The critical suspension propert...
