Abstract:

To facilitate the damping matching of dampers for vehicle passive suspensions, this paper proposes an analytical matching method of the optimal piecewise linear damping characteristics curve. Based on the vehicle vibration model, taking the suspension dynamic deflection as the constraint, by the vibration acceleration and the wheel dynamic load, an objective function about the relative damping coefficient was created. Using the integral mid-value law, an analytical formula of the optimal relative damping coefficient was established and the analytical matching method of the piecewise linear damping characteristics curve was presented. With a practical example, the effectiveness of the proposed matching method was validated by road test. The results showed that the method presented is workable, which has important reference value for fast damping matching of vehicle passive suspensions.

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...

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...
