Analysis of flow and aerodynamic noise behaviour of a simplified high-speed train bogie inside the bogie cavity
Aerodynamic noise becomes significant for high-speed trains but its prediction in an industrial context is difficult. The flow and aerodynamic noise behaviour of a simplified high-speed train bogie at scale 1:10 are studied here through numerical simulations. The bogie is situated in the bogie cavity and cases without and with a fairing are considered, allowing the shielding effect of the bogie...
متن کاملAnalysis of aerodynamic and aeroacoustic behaviour of a simplified high-speed train bogie
As one of the main aerodynamic noise sources of high-speed trains, the bogie is a complex structure containing many components and the flow around it is extremely dynamic with high-level turbulence. Flow around a simplified bogie at scale 1:10 is studied numerically using Computational Fluid Dynamics (CFD) for comparison with experimental measurements. The upstream inlet flow is represented as ...
متن کاملThe Experiment Study for Fatigue Strength of Bogie Frame of Beijing Subway Vehicle Under Overload Situation
In this paper, a problem for safety of bogie frame of subway vehicle under overload situation has been discussed. Firstly, the structure of bogie frame and service condition are introduced to explain the reason caused fatigue failure. Then, the testing points are selected in terms of the structure of bogie frame, the characteristics of processing technique, load transfer path and the operation ...
متن کاملDesign of the Video Streaming Proxy in High-Speed Train
This paper considers the characteristics of high-speed train in precise timing information, such as arrival time, depending duration on station, traveling time and location of the train, to design a video proxy agent for VoD service in train. Based on the information of current active video streams, a burst pre-fetching scheme in video proxy agent is developed when the high-speed train depends ...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
