“…In addition, the oscillation frequency of the sprung part should vary within a certain range. Such requirements are partially met by the suspension with nonlinear relationship between the restoring force and strain [19][20][21][22] and the adaptive suspension [3,4], which is used for passenger cars by leading automobile manufacturers [7]. However, analytical investigations of the dynamics of the sprung part of the wheeled vehicle with these types of suspensions have not been properly developed due to purely technical and mathematical problems.…”

“…This primarily concerns the ensuring of the movement smoothness, controllability, movement stability, etc. [5][6][7][8][9][10]. In order to create the software product for controlling the determining power parameters of such suspension system, a priori information about the response of the sprung part to the changes in various types of motion disturbances caused by external factors and changes in the speed of the wheeled vehicle remains a problem.…”

On the example of the plane model of wheeled vehicle oscillations with adaptive power characteristic of the suspension system, the methodology for selecting its main parameters that would maximize the movement smoothness is developed. To solve this problem, the mathematical model of relative oscillations of the sprung part is constructed, provided that they are carried out in the vertical plane. The latter represents the system of two nonlinear differential equations describing the relative displacement of the center of mass of the sprung part and the angle of rotation of the latter around the transverse axis passing through the center of mass of the specified part. To construct the approximate analytical solution of this equations system, and thus to describe the main parameters that determine the relative position of the sprung part under reasonable assumptions, the method of normal oscillations of nonlinear systems with concentrated masses is used. This made it possible to obtain the system of ordinary differential equations of the first order that describe the amplitude–frequency characteristics of the sprung part vibrations. Due to the analysis of the latter it is determined that at a certain ratio between the parameters describing the power characteristics of the suspension system, it can perform isochronous vertical and longitudinal–angular oscillations, and thus it is possible to achieve maximum comfort in transporting passengers or dangerous cargo over rough terrain. The main obtained results can be used to create the software product for adaptive suspension, and their validity is confirmed by: a) in passing to the limit, obtaining results known from literary sources; b) generalization, based on the use of periodic Ateb-functions, of widely tested analytical methods for constructing solutions of differential equations with strong nonlinearity.

“…Vehicle that encounter body roll caused by the driver that lost in handling due to the non-linear response of pneumatic automotive tires and vehicle's body rotates about its longitudinal axis (Kemal Caliskan, 2003). In order to have a better ride quality, there are two important factors that contribute to the stability and comfortability of the vehicle ride which are road condition and proper design of vehicle components (Soliman et al, 2008). However, to control the road condition is not within the area of this study and the only way to improve the ride quality is to improve the design of vehicle components.…”

In this study, understanding between the operation and mechanism of an automotive anti-roll bar is reviewed. Design consideration of the automotive anti-roll bar is studied from past researchers with the summarized of current invention of automotive anti- roll bar. In development of the automotive anti-roll bar, interaction between design elements such as material, function analysis, forces analysis, failure analysis and geometry specifications are essentially need to be considered in development of it without affecting its conventional function and achieve the performance target. The potential of the fibre reinforced composite such as natural fibre is likely to be the next future generation of automotive anti-roll bar. Considerations of the aforementioned design elements would help design engineers to outcome the challenges in design of composite materials. The inventions that patented by the past inventors would help as a guide.

“…One of the operating characteristics of wheeled vehicles (WV) is steerability [1,2]. It implies the ability of changing the traffic route of a car and keeping to the given direction due to the driver's action on the steering wheel, that finally results in an angle change between motion velocity vector of WV and steered wheels plane.…”

The effect of relative motion of cushion system on dynamic pressure force of steered wheeled vehicles with non-linear elastic characteristics of suspension was evaluated in the article under consideration. The problem is to find the dynamic force of system cushion-non-cushion part pressure on front wheel. The dependence for the limiting value of dynamic turning angle of steered wheels on longitudinal-and-angular oscillations amplitude and parameters describing elastic characteristics of elastic suspension was obtained. It was demonstrated that for more rigid suspensions the value of dynamic turning angle is smaller at small amplitudes of longitudinal-and-angular oscillations and bigger at big amplitudes of longitudinal-and-angular oscillations.
