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 کاملTrack Side Bogie Monitoring System
Introduction: Indian Railways at present does not use any automated system for real-time online monitoring of the performance of bogies and wheel-sets. Bogies are checked only during TXR examination for loose or broken parts. Wheel sets are changed when they reach the condemning limit. Problems like skew ness in bogie or asymmetric wheel-wear are attended to during preventive maintenance schedu...
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 کاملAny Good Vibrations with Bogie Tracks?
Forestry machines are often travelling on unprepared terrain, which means often rather bumpy ride.4-wheeled machines became 6-wheeled and later on 8 wheeled machines to alleviate the worst obstacles. Nordic forestry people discovered if these wheels were arranged in bogie construction the machine (usually a forwarder that could carry timber) both could better negotiate obstacles and with all wh...
