摘要：

With the increase in the train speed, the contribution of the quadrupole noise source to the aerodynamic noise of the train increases. When the running speed of the high-speed maglev train reaches 600 km/h, it is necessary to consider the influence of the quadrupole noise source on the aerodynamic noise of the high-speed maglev train. The numerical simulation method of the aerodynamic noise of the high-speed maglev trains considering the quadrupole noise source was set up. The local extrapolation of the integral surfaces for the streamlined tail and head regions of the high-speed maglev train was carried out, and the influence of the quadrupole noise sources of the streamlined tail and head regions on the aerodynamic noise of the high-speed maglev train was explored. The study shows that the wake vortex of the high-speed maglev train will pass the downstream integral surface. The fully enclosed integral surface can not be used for the streamlined tail region, or otherwise, it will produce large spurious noise. The integral surface for the streamlined tail region needs to extend more towards the wake vortex region and remove the region through which the wake vortex passes. The contribution of the quadrupole noise source of the streamlined head region of the high-speed maglev train is small, and the integral surface for the streamlined head region can be taken as the streamlined head surface. When the high-speed maglev train runs at a speed of 600 km/h, the aerodynamic noise energy of the high-speed maglev train caused by the quadrupole noise source accounts for 42%. © 2024 Science Press.
