Abstract
<p>It is known that bogie cavity of Shinkansen trains is a major source of low-frequency aerodynamic noise. To investigate the generation mechanism of low-frequency noise, we conducted CFD analysis using 4-car trainset model . The result shows that meandering flow attributed to the bogie cavity generate low-frequency aerodynamic sound around 6 to 10 Hz, and the pressure fluctuation around 20Hz within the bogie cavity was observed. We found, furthermore, that it is possible to reduce low-frequency aerodynamic sound by changing the shape of the front and back corners of the bogie cavity to a gentle slope, or by reducing the volume of the bogie cavity.</p>
