In order to make clear the mechanism of oil churning loss of gearbox and to further improve the efficiency of gear transmission,the factors that effects on oil churning losses are studied.The finite element model of oil fluid in gearbox is established in terms of the condition of the gear click here transmission under oil-immersed lubrication.The v
Given the problem of three-sources uncertainty in aero engine degradation process click here and the assumption of normal distribution of measurement error in existing research, a Wiener process aero engine residual useful life time(RUL) prediction method with logistic distribution of measurement error was proposed.Firstly, the performance degradat
The inherently brittle nature and the susceptibility to impact damage hinder the use of carbon/epoxy composite in some areas.In this study, poly ether ether ketone (PEEK) microparticles were incorporated to increase the resistance neflintw-r6mpw to delamination and interlaminar fracture toughness.A hand lay-up technique followed by compression mold
