<b>Method to Evaluate Aerodynamic Bogie Noise from Shinkansen High-speed Trains by Considering Acoustic Fields</b>
نویسندگان
چکیده
Aerodynamic bogie noise was quantitatively estimated at a wayside observation point by using spatial distribution of the sound pressure level (SPL) obtained two-dimensional microphone array in wind tunnel test. In order to evaluate SPL, it is necessary appropriately consider generation and field with respect various acoustic properties such as ground reflection insertion loss side cover. this study, transfer function between integrated SPL results an omnidirectional were calculated numerical method. The aerodynamic Shinkansen trains can be compared tests.

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 کاملExperimental Investigation of Noise Annoyance Caused by High-speed Trains
The observed difference in perceived annoyance caused by train and highway noise at the same averaged noise level, has led to the introduction of the ‘railway bonus’. This bonus has found its way to the noise legislation in many countries, leading to more relaxed restrictions on time averaged noise levels, LAeq. With the introduction of high-speed trains and train-like transportation systems ba...
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 کاملStudy on Braking Panels in High Speed Trains Using CFD
With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...
متن کاملEurostar e320 high-speed trains
In December 2010, Eurostar International Ltd. awarded Siemens a contract for ten interoperable 16-car highspeed trains. These trains are based on Velaro®, the world’s most highly diversified high-speed platform. Starting in 2014, these trains will be added to the existing Eurostar fleet operating on the London–Paris–Brussels line running through the Eurotunnel between Great Britain and the Euro...
