摘要

为了准确预测磁流变安装的动态特性，建立了磁流变液体与软磁材料之间的非线性电磁耦合规律和固液相互作用、电磁耦合和流固耦合数学模型以及磁流变安装的数值模拟模型。通过磁流变安装试验，将模拟结果与实验结果进行对比，验证了数值模拟模型的有效性。在此基础上，分析了电磁耦合在磁路中的分布效应。根据宾厄姆模型，推导出了磁流变流体阻尼力的变化规律。将磁场模拟结果引入流体模型和流固模型，计算了磁流变安装数值模型的流固耦合效应。模拟了磁流变安装在不同电流激励条件下的动态和静态特性。它为磁流变安装的多物理场仿真设计和仿真提供了基础。

Dynamic Characteristics of Magnetorheological Mounted Metal Rubber Structures Under Multi-physics Coupling Conditions

To accurately predict the dynamic characteristics of MR mounting, the nonlinear electromagnetic coupling law between MR liquid and soft magnetic material and the solid-liquid interaction, the electromagnetic coupling and fluid-structure coupling mathematical models and numerical simulation models of MR mounting are established. Through the magnetorheological mounting test, the simulation results are compared with the experimental results, and the validity of the numerical simulation model is verified. On this basis, the distribution effect of electromagnetic coupling in a magnetic circuit is analyzed. According to the Bingham model, the variation rule of magnetorheological fluid damping force was deduced. The magnetic field simulation results are introduced into the fluid model and the fluid-solid model, and the fluid-solid coupling effect of the numerical model of magnetorheological mounting is calculated. The dynamic and static characteristics of magnetorheological mounting under different current excitation conditions are simulated. It provides the basis for designing and simulating multi-physical field simulation of MR mounting.
