摘     要
 本论文以磁流变减振器的优化设计编程为主要目的，充分利用计算机作为有力的辅助工具，就已有的一些车辆减振器进行数学模型研究，并根据其结果计算得到适于要求的减振器结构尺寸。本次设计的具体对象为一种汽车磁流变减振器。
 论文的两部分主要任务就是磁流变减振器的建模和磁流变减振器的优化编程。首先是选择数学模型，建立模型后，应用它对减振器进行特性分析，优化减振器的性能，改进减振器的结构和尺寸，设计出符合要求的减振器。有了Mat lab这个软件可以简化优化设计的过程，提供计算的方便。根据计算和优化后的设计方案来设计磁流变减振器的尺寸。

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.
