| 摘 要： | 首先介绍了铅-磁流变阻尼器（LMRD）的构造与特点。然后根据LMRD试验测得的滞回曲线，提出了该阻尼器的力学模型-Michaelis-Menten模型，并对模型参数进行了识别。最后通过将模拟结果与试验结果进行对比对模型进行了验证。结果表明:Michaelis-Menten模型能描述电流、位移幅值和激励频率对LMRD力学性能和非线性滞回性能的影响。

| Abstract: | The composition and characteristic of a Lead Magnetorheological Damper (LMRD) were introduced firstly. Then according to the hysteresis curves obtained from the test of LMRD, a Michaelis-Menten model of an LMRD was proposed, and the parameters in this model were then identified. Finally, the proposed model was verified by comparing the numerical results with the experimental results. The comparison results show that the Michaelis-Menten model can describe the effects of current, displacement amplitude and excitation frequency on mechanical property, and nonlinear hysteresis behavior of the LEMR damper. |
