| 中文摘要: |
| 提出了一种新型多圆孔磁流变阻尼器，基于Bingham模型，推导了阻尼力计算方程。磁流变液通过多孔隙时压力梯度与磁流变液的黏度、屈服强度、孔隙阀孔径与孔数的关系为四次代数方程，应用代数方程理论得到了压力梯度的理论解。由于理论解过于复杂，采用了一种近似解计算磁流变液的压力梯度，该近似解与理论解误差很小。 |

| In this paper，the damping force of Magnetorheological dampers with multi hole ducts valve is analyzed using quasi static axi symmetric model. Based on Bingham model，the equation of Magnetorheological fluid through outlay multi hole ducts valve is derived. The relationship between the pressure gradient，the structure parameters of MR damper and the performance parameters of Magnetorheological fluid is shown as a quartic algebraic equation. The analytical solution of the pressure gradient equation is obtained by algebraic equation theory. Because of the complexity of the analytical solution，an approximate solution which is in close agreement with the analytical solution is given. |
