中文摘要：

由于能量耗散生热、环境温度以及通电线圈产生的热能会使磁流变阻尼器在很大的温度范围内工作,温度对磁流变阻尼器输出阻尼力有很大影响。因此有必要研究温度对磁流变阻尼器输出特性的影响,建立能在较大温度范围预测磁流变阻尼器阻尼力的数学模型。文章从Bouc-Wen模型出发,通过温度试验数据,建立了能在较大电流范围和温度范围内使用的数学模型,并用1st Opt软件的通用全局优化算法（UGOA）识别模型参数,结果表明该模型能很好地体现磁流变阻尼器不同温度时的阻尼特性。

英文摘要：

MR damper will work in a wide of temperatures range due to the heat from energy dissipation,ambient temperature and thermal addition of energized coil,therefore it is necessary to test the influence of temperature on output characteristics of MR damper and establish the mathematical model that can predict the MR damper damping force at a large of temperatures range.To this end,this paper propose a new model that can be used in a wide current range and temperature range based on Bouc-Wen model and the temperature experimental data,and its parameter can be obtained by using Universal Global Optimization Algorithm（UGOA） of 1st Opt software,verification shows that the model can reflect the damping characteristics of MR damper at different temperatures.
