Abstract
This thesis takes the optimal design of magnetorheological fluid shock absorber by programming as major objective，fully utilizing the computer as the forceful auxiliary implement. The mathematic model was established by analyzing some vehicle shock absorbers, and calculate the shock absorber structure dimension being suitable for a request according to whose result. The concrete marriage partner who designs that originally time is one kind of automobile magnetism flowing deformation shock absorber.
Two parts among them major tasks it is magnetism the to flowing deformation shock absorber's building the model and the magnetism flowing deformation shock absorber optimization programming. Be to choose mathematic model first, found the model queen, the characteristic property applying it being in progress to the shock absorber is analyzed, optimize the shock absorber function, and improve shock absorber structure and dimension, design out the shock absorber according with request. Have had Mat lab this software can facilitate the process that the optimization designs. provide calculative going to the lavatory. Dimension according to the shock absorber coming to design magnetism flowing deformation the design plan secretly scheming against and optimizing the day after tomorrow's.
