One-Quarter-Car Active SuspensionModel Verification

Usage of One-Quarter-Car Active Suspension Test Stand for Experimental Verification

Suspension system is an important part of the car design, because it influences both the comfort and safety of the passengers. In the paper an active suspension using linear electric motor is designed. In particular, the article is focused on experiments with active suspension – developing an appropriate input signal for the test sand and evaluation of the results. Second important point of the...

On Testing of Vehicle Active Suspension Robust Control on An One-Quarter-Car Test Stand

Between 2010 and 2014, the research team of Josef Bozek ́s Research Center of Combustion Engines and Automobiles at the Czech Technical University in Prague, Czech Republic, has developed innovations in vehicle suspension technology. The research team has designed a unique innovative suspension system that uses a linear electric motor as a controlled actuator. We have undertaken many experiments...

Robust Control of Quarter-car Semi-active Suspensions

This paper deals with single-wheel suspension car model. The benefits of controlled semi-active suspensions compared to passive ones are here emphasized. The contribution relies on robust analysis of a controller which improves comfort and road holding of the car under industrial specifications. Simulations on an exact nonlinear model of the suspension are performed for control validation.

Simulation OF Quarter Car Model

The automobile suspension’s design incorporates three conflict criteria’s which are road handling, load carrying and passenger comfort. All these suspensions systems are generally require maintaining vehicle stability by reducing the effect of dynamic loads. The response of system is simulated by using the software “Symbol’s Shakti”. The bond graph model of the system with active and passive su...
