The paper presents the modeling and control design of a variable-geometry suspension system, which is applied as independent wheel steering for in-wheel electric vehicles. The variablegeometry suspension modifies the tilting of the wheel, which has an effect on the steering of the wheels through the variation of the scrub radius. In the paper the model of the suspension-steering system and the ...

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...

In this work we obtain a new description of the vertical motion of the car including the active suspension. It consists of 4 completely decoupled subsystems. The first 3 ones are of order 4 each and they are analogous to standard quarter car suspension models. The 4th subsystem is of order 2 and it introduces a new abstract variable denoted by γ. One of the novelties of this modeling result is ...

ESP can help the road vehicle to improve driving dynamics and prevent accidents which result from loss of control. Based on the theory and account method of Multi-body System Dynamics, the Multi-body System Dynamics model of an A-class car is built by the ADAMS/Car software, which includes steering system, front and rear suspension, braking system, body, and so on. In order to study the handlin...

Target cascading in product development is a systematic effort to propagate the desired top-level system design targets to appropriate specifications for subsystems and components in a consistent and efficient manner. If analysis models are available to represent the relevant design decisions, analytical target cascading can be formalized as a hierarchical multilevel optimization problem. The a...

the aim of this manuscript is to study the implication of aluminium-oxide nanofluid for an amphibious vehicle engine (viable on land and under water) cooling system both analytically and experimentally. to achieve this, a one-dimensional model of the engine cooling system (radiator) is considered through a computational fluid code in which the mass flow rate for a range of the coolant temperatu...

non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. in this paper, an optimal linear quadratic regulator (lqr) controller for roll-yaw dynamics to articulated heavy vehicles is developed. for this purpose, the equations of motion obtained by the matlab softwar...
