Suspensions may be defined as preparations containing finely divided drug particles (the suspensoid) distributed somewhat uniformly throughout a vehicle with or without stabilizers and other additives in which drug exhibits a minimum degree of solubility hence conventional oral suspension can be administered immediately (ready to use form) and not requiring reconstitution at the time of dispens...

Two methods for parameters optimization of traditional passive suspension based on the invariant point theory are presented in this paper. Firstly, the two degree-of-freedom dynamical model for a quarter vehicle suspension is established. Then all the invariant points for the acceleration of INTERNATIONAL JOURNAL ON SMART SENSING AND INTELLIGENT SYSTEMS VOL. 6, NO. 5, DECEMBER 2013

Aiming at the negative vibration effect caused by increased unsprung mass of hub motor-air suspension (HM-AS) vehicle and unbalanced magnetic force (UMF) motor, a linear quadratic regulator (LQR) air control strategy based on genetic algorithm is proposed. Considering coupling road surface excitation UMF, model HM-AS established. Then, according to optimal theory algorithm, LQR controller desig...

The topic of this paper is the design and analysis of a control system for a semi-active suspension in a 2-wheel vehicle. The control system is implemented via a semi-active electro-hydraulic damper located on the rear suspension of a hypersport-class motorbike. The entire design and analysis procedure is outlined: the semi-active damper is analyzed and characterized; a wide range of control st...

According to a company developed twelve meters bus, using the multi-body dynamics software ADAMS, they reached the conclusion that the change scope of the toe angle, and camber in the guide mechanism with wheel vertical, affects the operation stability. Utilizing: i) the air suspension guide mechanism of spatial position as design variables, ii) the front wheel alignment parameters as the objec...

The semi-active suspension system can instantly change the damping coefficient depending in order to ‘stiffen’ or ‘soften’ the system. It will effectively and timely eliminate road disturbances on the car body. Thus, research on the semi-active suspension system is necessary. According to the performance test of the proposed adjustable damper, the different damping coefficients can be selected ...

The formula cars need high tire grip on racing challenge by reducing rolling displacement at corner or double change lands. In this case study, the paper clarifies some issues related to suspension system with inerter to reduce displacement and rolling angle under impact from road disturbance on Formula SAE Car. We propose some new designs, which have an advance for suspension system by improvi...

This paper is concerned with the problem of multi-objective H∞ control for vehicle active suspension systems with random actuator delay, which can be represented by signal probability distribution. First, the dynamical equations of a quarter-car suspension model are established for the control design purpose. Secondly, when taking into account vehicle performance requirements, namely, ride comf...
