ВИЗУАЛИЗАЦИЯ АКУСТИЧЕСКИХ ШУМОВ ЭЛЕКТРИЧЕСКОГО ТРАНСПОРТА
Journal Title: Science Review - Year 2018, Vol 2, Issue 3
Abstract
Currently, there are many projects being developed and put into practice and operating pilot trains with electric drive in the form of monorails with magnetic cushions and linear motors. However, these solutions are a source of high-intensity noise in the passage of air in the gap between the rail and the magnetic shoe. At high speeds, which are the main advantage of the projects, noise increases, in addition, it is enhanced by the number of pairs - "magnetic shoe - rail", available in large quantities. This creates aerodynamic noise. There are complex, cumbersome calculations and not fully investigated noise generation processes, the main role in which is occupied by the shape and processing of surfaces interacting with the air and gas medium, which for brevity we call an acoustic pair. The shortest and least laborious is the physical modeling of these processes.
