[摘要] 從工程應(yīng)用的角度出發(fā)，對采用不同冪指流體時(shí)粘滯流體阻尼器的輸出力計(jì)算公式進(jìn)行推導(dǎo)，分析了流體的冪指關(guān)系對粘滯流體阻尼器力學(xué)性能的影響規(guī)律。通過對影響阻尼器系數(shù)的其他因素進(jìn)行分析，給出了冪指關(guān)系的粘滯流體阻尼器的阻尼孔面積組合原則。推導(dǎo)的理論公式的計(jì)算結(jié)果和試驗(yàn)結(jié)果符合，誤差在10%，為粘滯流體阻尼器的實(shí)際工程應(yīng)用提供了依據(jù)。

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.lt 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.
