Analytical Matching of Optimal Damping Characteristics Curve for Vehicle Passive Suspensions

Comparative Research on Optimal Damping Matching of Seat System for an off-Highway Dump Truck

To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...

Research on Damping Characteristics of Shock Absorber for Heavy Vehicle

The damping characteristic of shock absorber has an important influence on its design and overall performance of vehicle system. Firstly, the structural features and working principle of hydraulic shock absorber are introduced. Then the detail testing scheme of the shock absorber is proposed and the damping characteristics are tested under both sinusoidal and random displacement excitation (HT-...

Performance Benefits in Passive Vehicle Suspensions Employing Inerters1

A new ideal mechanical one-port network element named the inerter was recently introduced, and shown to be realisable, with the property that the applied force is proportional to the relative acceleration across the element. This paper makes a comparative study of several simple passive suspension struts, each containing at most one damper and inerter as a preliminary investigation into the pot...

Optimal and Robust Damping Control for Semi-active Vehicle Suspension

The paper focusses on optimal control issues arising in semi-active vehicle suspension motivated by the application of continuously controllable ERF-shock absorbers. Optimality of the damping control is measured by an objective consisting of a weighted sum of criteria related to safety and comfort which depend on the state variables of the vehicle dynamics model. In the case of linear objective...

Secure Urban Design in Terms of Passive Defense Approach; Analytical Considerations for Improving Form-based Characteristics in Iranian Cities

Pareto Optimal Design of Passive and Active Vehicle Suspension Models

It would be difficult to deny the importance of optimization in the areas of science and technology. This is in fact, one of the most critical steps in any design process. Even small changes in optimization can improve dramatically upon any process or element within a process. However, determining whether an optimization approach will improve on an original design is usually a question that its...
