Description

Technical field [0001] The invention belongs to the technical field of train aerodynamic performance simulation test, and specifically relates to a train aerodynamic performance simulation model test device and a test method thereof. Background technique [0002] With the development of railway transportation, more and more people choose trains as their means of travel. Among the many modes of travel, trains are deeply loved by people for their advantages of fast speed, low energy consumption, low noise, no pollution, and safety. However, people have higher demands on the speed and comfort of trains. Therefore, researchers have conducted a lot of research on the train aerodynamic performance simulation dynamic model test device. [0003] Compared with the usual driving technologies such as explosive devices, air cannons and light gas cannons, electromagnetic railguns drive projectiles at a much higher speed. At present, the orbital guns of the US LANL / LLNL joint research group ha...
