摘要:
基于Bingham塑性模型的基本思想,建立了一种简单的磁流变阻尼器非参数模型。该模型假设MR阻尼器的阻尼力由3项构成:气囊力、MR流体粘性阻尼力以及由于磁场作用所引起的阻尼力。气囊力被表示为活塞位移的线性函数。磁场引起的阻尼力则表示为一个没有线性增长的磁滞环。理论与实验结果的比较指出:非参数模型数据与实验数据吻合较好。该文所提出的模型,具有各参数物理意义清晰,容易根据实验数据确定的特点,可以用来描述一类线性比较好的MR阻尼器。
Abstract:
Based on the basic idea of Bingham plastic model, a non-parametric model of magneto-rheological (MR) damper is proposed. ThisMR damper model assumes that the damping force of the MR damper consists of three parts: gas chamber force, viscous damping force of MR fluid, and damping force duo to the applied magnetic f ield. The gas chamber force is expressed as a function of the piston displacement. The damping force due to magnet ic field presents a hysteresis loop without linear increase. Sigmoid function is chosen to describe this hysteresis behavior. Its peak value is also a function of the applied current. The comparison of theoretical and experimental results shows that this non-parametric model reflects the dynamic behavior of the usedMR damper reasonably. The parameters in this non-parametric model have clear physical meanings, and they are easily determined through experimental data as well. The proposed non-parametric model is used to describe some MR dampers that have good linearity.
