摘　　要：被动式微量供油是空间轴系实现微量润滑的主要形式之一,润滑油的适量供给是保证空间轴系稳定运转的关键环节。针对空间轴系用多孔材质芯阀在传统跑合筛选技术中存在的耗时长、成本高等问题,提出采用空气代替航天润滑油作为流体介质对芯阀供油率进行快速检测的等效方法,并基于水下气泡法和LabVIEW图像识别技术研制了芯阀气体渗透率检测装置。对装置检测性能进行测试试验的结果表明:该装置对多孔材质芯阀的气体渗透率检测用时小于5 min,检测误差小于0.5%,供油率预测误差小于6.0%。Passive micro oil supply is one of the main forms of achieving micro lubrication in space shafting,and the appropriate supply of lubricating oil is a key link to ensure the stable operation of space shafting.In response to the problems of long time consumption and high cost in traditional running-in screening technology for porous material core valves used in space shafting,an equivalent method was proposed to quickly detect the oil supply rate of core valves with air instead of aerospace lubricating oil as the fluid medium.A core valve gas permeability detection device was developed on the basis of underwater bubble method and LabVIEW image recognition technology.The results of testing the detection performance of the device show that the gas permeability detection time for the porous material core valve is less than 5 minutes,the detection error is less than 0.5%,and the prediction error of the oil supply rate is less than 6.0%.
