An analytical investigation of a half-car model including passenger dynamics, subjected to random road disturbances is performed, and the advantage of active over conventional passive suspension systems are examined. Two diierent performance indices for optimal controller design are proposed. The performance index is a quantiication of both ride comfort and road handling. Due to practical limit...

Many phenomena and systems in science and engineering may be accurately modeled by systems of IVP (initial value problem) ODEs (ordinary differential equations). As two simple examples, at rather different scales, we cite the dynamics of an automobile suspension and the motion of the planets in our solar system. In this nutshell we describe the essential preparations and ingredients for numeric...

Suspension is the general name of device that connects conductive force between car body and wheels. Among them, operational stability ride comfort are two contradictory requirements in actual driving. In traditional vehicle suspension system, order to maintain vehicle, vibration energy caused by uneven road surface usually dissipated passive shock absorber form heat. If this part can be recove...

Abstract We performed a laboratory investigation at 1,873 K using MoSi 2 furnace to study the effect of refractories on inclusions in 55SiCr suspension spring steel. Three types crucible materials (Al O 3 , MgO·Al and MgO–CaO) were investigated. The results this indicated that SiO Al not suitable for making By contrast, MgO–CaO was perfect choice producing advantages crucibles smelt steel summa...
