| 摘 要： | 从工程应用的角度出发,对采用不同幂指流体时粘滞流体阻尼器的输出力计算公式进行推导,分析了流体的幂指关系对粘滞流体阻尼器力学性能的影响规律。通过对影响阻尼器系数的其他因素进行分析,给出了幂指关系的粘滞流体阻尼器的阻尼孔面积组合原则。推导的理论公式的计算结果和试验结果符合,误差在10%,为粘滞流体阻尼器的实际工程应用提供了依据。

| Abstract: | From the viewpoint of the actual application,it deduces the calculation formula of the viscous fluid damper's output force adopting exponential fluid as damp material.The influence rule of the fluid exponential relation acting on the viscous fluid damper's mechanics character is investigated.It also analyses other factors influencing the damp and gives the combining principle for area of damping hole,and compares it with the experiment result.The error between the two results is ten percent.The derived formula could be reference for engineering application. |
