This paper proposes the design of reconfigurable suspension systems in road vehicles. The purpose of the suspension system is to improve passenger comfort and road holding during travel and improve safety during various maneuvers. In the modeling the nonlinearities in the suspension system, the changes in the forward velocity and the change of the adhesion coefficient between the tire and the r...

The superconducting magnetically levitated transport (Maglev) system is conceptualized as a next-generation high-speed transportation system. For practical use, it is important to achieve adequate ride comfort particularly in high-speed running. Maglev vehicles are composed of lightweight car bodies and relatively heavy bogies which are mounted with devices such as superconducting magnets (SCMs...

With steer-by-wire, suspension and steering systems are no longer governed by purely mechanical criteria but must instead be designed according to mechatronic considerations. This paper demonstrates an approach to steer-bywire suspension design in which geometric design variables are chosen to render the tire reaction torque about the steer axis highly predictable. This predictability, in turn,...

The modular modeling of the 3-dimensional mechanics of a racing car with Modelica is discussed. For example, one base model class of the wheel suspension is defined and used to model 4 occurences in the front and rear suspension. This model of the car is based on a new Modelica library to model 3-dimensional mechanical systems. This library is explained in some detail.

Seven different suspension systems for below-knee prostheses were tested on 20 adult, unilateral amputees. All subjects walked with a prosthesis. Gait was evaluated with regard to longitudinal and vertical accelerations of the body, forward velocity, axial (piston) movement of amputated limb in the socket, and knee movement. Harmonic analyses of variable waveforms provided the primary method to...

suspension system is one of the most important factors in provision of ride comfort and dynamic stability in any vehicle. meanwhile the suspension systems of tracked vehicles, due to their continuous track, have particular specification in comparison with other vehicles. this specification causes tracked vehicles having an improved dynamic stability in off-road maneuvers compared to vehicles wi...

This paper presents the modeling and simulation of a magnetorheological damper based semiactive suspension using variable structure controllers. Passive suspension systems tend to limit the trade-off between passenger comfort and road handling. But Semiactive suspensions can reduce this trade-off margin and dynamically respond to the damping requirements. Active suspensions provide the best res...

Objective(s): Studies indicate that major deficiency in the levels of monoaminergic transmitters is a reason for severe depression. On the other hand, it is shown that Carthamus tinctorius L. (CT) may improve neuropsychological injuries by regulation of the monoamine transporter action. Hence, the present study was undertaken to evaluate the involvement of monoaminergic systems in antidepressan...
