Abstract


Suspension is the key components that affect vehicle performance, using real-time control of intelligent suspension according to road conditions and vehicle operating status is an important way to improve vehicle ride comfort and safety. Magnetorheological semi-active suspension using magneto-rheological technology to achieve real-time damping control, excellent controllability, a wide dynamic range, high response speed, low power consumption, a relatively simple structure, has become hot research field of Intelligent Suspension favored. In this paper, theoretical analysis and numerical simulation of the dynamic characteristics of the magnetorheological damper, of vehicle magnetorheological semi-active suspension dynamics characteristics, a semi-active suspension control strategy and control system design. Specific work includes the following aspects: (1) illustrates the importance of the study of intelligent suspension reviewing the the Intelligent Suspension study history and progress of magnetic fluids, magnetorheological damper and vehicle semi-active magnetorheological Research and suspension problems, vehicle magnetorheological semi-active suspension problems existing major work to be carried out herein. (2) nonlinear vehicle suspension system, the paper vehicle semi-active suspension intelligent control for the study, based on the model of magnetorheological damper and two degrees of freedom quarter vehicle suspension model magnetic rheological semi-active suspension model, designed for vehicle semi-active suspension geometry differential controller and fuzzy controller and Matlab software toolbox magnetorheological semi-active suspension simulation system, through numerical Simulation analysis of the above control strategy magnetorheological time domain response of a semi-active suspension under the control effects of the two control strategies were compared and evaluated. (3) by comparison with the switch damping control simulation results, both for the semi-active suspension with non-linear characteristics of nonlinear control method is feasible. Power spectrum analysis tends to be more energy than switching semi-active suspension control system after an average, more stable suspension dynamic performance. (4) two nonlinear control method of simulation to analyze the results show that: the fuzzy control control suspension shock response, low vibration intensity, superior performance than the differential geometric control.
