高耗能自解耦式MR阻尼器的设计及性能试验
|
摘要
为设计制作基于土木建筑结构振动控制的高耗能自解耦式磁流变(magneto-rheologcal,简称MR)阻尼器,通过对阻尼器设计的关键技术、阻尼器的性能试验及力学模型的参数识别进行研究,得知在副活塞中设置解耦装置可使阻尼器在不同的振幅下具有不同的刚度和阻尼特性,在主活塞中将永久磁场和电流磁场结合起来实现阻尼器的逆向控制的设计思路是可行的,铜制隔磁环的设置保证了磁力线沿理论设计的路径穿行,又使线圈避免与磁流变液的长期接触腐蚀,从而提高其耐久性。通过对阻尼器采用基于反正切函数的MR阻尼器模型进行参数识别,得到了与试验结果吻合的MR阻尼器的力学模型。
A self-decoupling magneto-rheological(MR) Damper,which is used for civil infrastructure vibration control,is designed and manufactured with 360kN maximal output force.The crucial technique for designing damper,performance test of the damper and mechanical model parameters identification are mainly studied.The performance test results of the MR damper show that the damper,including decoupling device in side-piston,has different stiffness and damping in case of different amplitude.It is feasible for the inverse control of the damper to be implemented by combining the permanent magnetic and the electro-magnetic field in main piston.The application of the isolating magnetic hoop can assure the magnetic lines to run along the theoretical designed path,and also raise the durability of the damper by avoiding the direct contact between the coils and MR fluid.The parameters of arctangent function model are identified and the theoretical results are consistent with the experimental results.
