Research On Dynamic Model For Vibration Isolation System Of Engine Based On Magnetorheological Mount

Because the internal combustion engine becomes high-speed,more power, lighter, the problem of vibration and noise appear to be more serious. So the requirements for controlling vibration and noise are increasingly stringent, more attention will be given to the research on the engine vibration problems. Isolating the engine vibration will not only protect engine from damaging, but also optimize the work performance, even to extend the service life of vehicles, and it can be prevent vibration disturbing other on-board equipment Instruments on work.Comfortable will can been Improved,and it reduces interference from the surrounding.Now an of system dynamics model of development that will be the engine vibration isolation system dynamics model of concrete, detail-oriented model is now the main trend. YND485Q combination of the papers to establish the diesel engine test stand, according to the test bed of concrete, respectively the establishment of the six degree of freedom and the freedom of engine vibration isolation system dynamics model.The article discuss the researchs about the magneto-rheological isolator, it seems to see that more scientific and technical persons will research magneto-rheological material for a period of time in the future.Then it analysis the development of system dynamics, and it can be conclusioned that trendence of model for Dynamic model for vibration isolation system of engine is becoming more specifics and detail.The model for construct 6 DOF automobile semi-active of Dynamic model for vibration isolation system of engine can be established according to the test bed of concrete and combination designed.Papers also studys rubber isolator and performance of isolator of the magneto-rheological itself , obtain the stiffnes and Damping, Tests rubber isolator and isolator magnetorheological engine individually,and handles these datas,compares vibration isolation performance of rubber vibration isolator and the magneto-rheological properties Things apperas that smart damping materials magnetorheological isolator have a obvious better effect than rubber isolator in all conditions. It confirmed that the magneto-rheological smart materials have better performance,and a broader application. at the automotive industry.
