CFD 해석을 통한 변속기 시스템 성능 향상 방안
변속기 시스템은 엔진에서 바퀴로 동력을 전달하기 위한 기어, 베어링 샤프트 등의 부품들로 구성됩니다. 각 구성품들은 운전에 의한 마찰로 발생된 열로 인해 손상되거나 열화 될 수 있습니다. 또한 운전 시 사용되는 오일량이 줄어들 경우 처닝로스가 발생되며 이는 시스템 과열의 잠재적 원인이 되기도 합니다. CFD 해석은 변속기 시스템의 이러한 열에 의해 발생되는 손실을 최소화 하며 성능을 극대화 하기 위한 조건을 구현하는데 이용할 수 있습니다. 또한 변속기 내부의 유동 현상을 예측하며 이를 개선하는데 있어서 시험을 통해 찾기는 매우 어려우며 CFD 해석은 공기와 오일 간의 혼합 정도를 도출하여 최적의 유동 패턴을 찾아내어 시스템의 윤활 성능을 개선시키는데 사용할 수 있습니다. 최근 개발된 다상체적법(VOF)과 중첩 격자(Overset Grids) 기법을 변속기 시스템 해석에 적용함으로써 기어의 움직임을 보다 쉽게 묘사 할 수 있으며 기어와 유체간의 상호작용을 안정적으로 모델링 할 수 있습니다. 이번 동영상에서는 변속기 시스템의 오일 유동과 기어의 작동을 묘사하기 위해 사용된 CFD 해석 기법을 소개합니다.
If you are an engineer or a manager who wants to optimize current processes in ways it was never possible before, this event will help you understand the applicability of deploying simulation to achieve these objectives. If you are already using CFD in your engineering workflow, this session will demonstrate that it is not a single point simulation but rather the ability to rapidly and intelligently explore a host designs and processes that bring the most value from simulation.

Charts are important - they play a primary role in decision-making when it comes to evaluating CFD results. Have you ever counted how often you change a chart after you’ve first created it? I’ll speculate it’s more than you think… you’ll probably want to change line and symbol colors and styles, change the range on both axes, change the fonts, and then change the colors again… these picks and clicks and scrolls take time. If you are using Excel or Matlab to create your charts, you lose the implicit connection between the chart and the data sources within your .sim file - going back and forth between the two costs you more time. Worse still, if you’re used to a certain plotting package, there are differences compared to STAR-CCM+® on where in the UI you need to make those changes. In having to switch back and forth between plotting packages, the time spent looking for where you need to make a change is potentially greater than the time needed to actually make it. To understand and communicate the information your charts contain more quickly, and to make your finalized charts faster in STAR-CCM+, version 12.02 introduces Chart Highlighting.
Join us as for a free, two-day event designed for engineers and managers involved in the ground transportation industry. With over 200 commercial attendees expected, this is an event you don't want to miss.
Software development is sometimes similar to raising a child. After the excitement of a new arrival with tentative steps and the promise of great things in the future, it develops into a moody teenager, usually working well but prone to tantrums. The final stage for both children and software is a graduation to a responsible adult, working well, providing benefits, and giving great results. Has EHP finally taken the last step and matured? Has the prodigy child finally turned into a responsible adult? Ever since its inception and first tentative steps in the market as an add-on, we at Siemens PLM and our clients have had to live with its tantrums and acts of genuine helpfulness. The teenage years were particularly difficult, not wanting to move on from version 9.06 while its big brother STAR-CCM+® went seamlessly through its three releases per year gears.
