상용 소프트웨어를 이용한 자동 변속기 주축의 변속기유 윤활경로 해석 연구 = A study on the Lubrication Behaviors of Automatic Transmission Fluid inside the Main Shaft through the Oil Holes by Fluent

다국어 초록 (Multilingual Abstract)

The durability of an automatic transmission is greatly affected by the ATF(automatic transmission fluid) flow behaviors inside the transmission. However, it is very difficult to exactly estimate the flow rates of ATF at each part of automatic transmission, because of its structural complexities especially when it is under the operating conditions. This computational study by commercial software, Fluent on axial cavity flow behaviors of ATF through the hollow main shaft simulates the discharge flow rates through the oil hole when it is under the operating conditions. ATF horizontally enters into the hollow main shaft by the oil pump and discharges through the oil holes into open air under the rotating conditions. Oil supply flow rate, supply pressure, rotational speed of shaft and magnitude of oil hole diameter are varied in the simulation. Under the variations of these parameters, flow rates through the oil holes are investigated. This study is believed to be the start point for the optimal design of the lubricating system in the automatic transmission.
