磁流变阻尼器力学性能及减震试验研究
|
摘要
通过RD1097型MR阻尼器的力学性能试验,获得不同频率、不同振幅、不同输入电流下的阻尼力与位移、速度的关系曲线;提出一种改进的MR阻尼器反正切函数非线性模型;采用RD1097型MR阻尼器,进行正弦波和El-Centro波下的MR阻尼器减震试验研究。研究结果表明:提出的阻尼器力学模型具有识别参数少、编程方便、精度较高等特点,不仅能较准确描述低速下阻尼力与速度的关系,而且能模拟摩擦滞后效应,对于固定频率振动和随机地震波下的阻尼力模拟有效;MR阻尼器具有较好的减震效果,在El-Centro波激励下,可使位移峰值及其均方根分别减小62.75%和77.17%。
The force-displacement and force-velocity curves of MR damper at different frequencies,amplitudes and input currents were obtained by the mechanical behavior test of RD1097 type MR damper.Furthermore,an improved arc tangent function nonlinear model of MR damper was put forward,and the seismic response reduction test of the above type MR damper under the sine wave and El-Centro wave was implemented.The results show that the improved MR damper mechanical model has the characteristics of less identifiable parameters,programming conveniently and high precision,and it can not only describe the relationship between the damping force and displacement precisely,but also simulate frictional lagging effect well.It is very effective for the model to simulate the damping force during invariant frequency vibration and random seismic waves.The structure response with MR damper can be evidently controlled.With the excitation of the El-Centro wave,the peak and its average square root of the displacement response with MR damper decrease by 62.75% and 77.17%,respectively.
