This paper presents an optimal vehicle and seat suspension design for a half-car vehicle model to reduce human-body vibration (whole-body vibration). A genetic algorithm is applied to search for the optimal parameters of the seat and vehicle suspension. The desired objective is proposed as the minimization of a multi-objective function formed by the combination of seat suspension working space ...

In the last few years, different linear and non-linear control techniques have been applied by many researchers on the vehicle suspension system. The basic purpose of suspension system is to improve the ride comfort and better road handling capability. Therefore, a comfortable and fully controlled ride can not be guaranteed without a good suspension system. The suspension system can be categori...

Cephalexin for Oral Suspension, USP, is a pink colored powder forming pink colored suspension on constitution. After mixing, each 5 mL of cephalexin for oral suspension, will contain cephalexin USP equivalent to 125 mg (360 μmol) or 250 mg (720 μmol) of anhydrous cephalexin. The suspension also contains the following inactive ingredients: colloidal silicon dioxide, FD&C Red No. 40, sodium benzo...

The paper presents experimental results on modelling and simulation of vehicle suspension. Testing the performance practice of suspension dampers is performed using a device called Spider8, which is achieved by a mathematical model to assess the behaviour and performance suspension behaviour experimentally tested through simulation environment under MATLAB/ Simulink. From the experimental data ...

The presence of fast and slow modes in vehicle suspension systems, based on a half car model, is utilized in the design of active suspension control using singular perturbation theory. This strategy is based on the slow-fast control design. The suspension system performance is optimised with respect to ride comfort, road holding and suspension rattle space as expressed by the mean-square-values...

Abstract: This paper proposes a nonlinear backstepping control strategy to improve the inherent tradeoff between ride comfort of passengers and suspension travel. Passenger comfort in ground vehicles usually depends on a combination of vertical motion (heave) and angular motion (pitch and roll). Suspension travel means the space variation between vehicle body and tires. Our active suspension de...

An articulated vehicle suspension comprising a parallel combination of energy restoring and dissipative elements and a feedback controlled force generator is analyzed using Linear Quadratic Gaussian (LQG) control technique. Ari ideal active suspension scheme is formulated to minimize a quadratic performance measure comprising ride quality, cargo safety, suspension and tire dynamic deflections, ...

Zeta potential, effective diameter and sedimentation rate of TiO2 (Degussa P-25) suspension were studied in the presence of NaCl and anionic (sodium dodecyl sulfate, SDS) or cationic (dodecyltrimethylammonium bromide, DTAB; tetradecyltrimethylammonium bromide, TTAB; and hexadecyltrimethylammonium bromide, CTAB) surfactant, as well as lecithin (1,2-dipalmitoyl-sn-glycero-3-phosphocholine, DPPC)....

Drying simulations of nanoparticle suspension films on a substrate are carried out by a threedimensional simulator developed. The motion of nanoparticles in the suspension films is modeled by Langevin equation, in which forces exerted on each nanoparticle consist of contact force, capillary force, Brownian force, van der Waals force, electrostatic force and fluid drag force. The drying of suspe...
