| 摘 要： | 液压阻尼器是某型机旋翼研制中的关键元件。本文根据直8液压减摆器性能试验结果拟合出直8型机液压阻尼器力—速度曲线,获得直8型机液压阻尼器定压活门开启速度;采用数值仿真方法对直8液压阻尼器和某型机液压阻尼器轴向速度进行了计算;采用薄壁小孔等效阻尼系数计算公式对直8液压阻尼器和某型机液压阻尼器节流片节流孔面积进行了计算;同时进行了某型机液压阻尼器补油装置油液体积的计算。上述计算方法和计算结果可为某型机液压阻尼器结构设计提供依据。

| Abstract: | Hydraulic damper is a key component for one type helicopter rotor manufacturing.According to the Hydraulic damper's performance test results of Z8,we obtain a fitting curve about force-velocity in this article,which gain the opening speed of pressure valve for the Hydraulic damper.on one hand,we calculate the axial velocity of Hydraulic damper of Z8 and Zx(one type helicopter) by numberical simulation methods.on the other hand,we also calculate the orifice area by equivalent damping factor formula about sma... |
