HIGHLIGHTS
- who: Jing Guo and colleagues from the College of Mechanical Hunan Institute of Science Technology, Yueyang, China, South University, Changsha, China have published the research work: Aeroacoustic Optimization Design of the Middle and Upper Part of Pantograph, in the Journal: (JOURNAL)
- what: In terms of pantograph aerodynamic noise optimization measures, the main focus is on optimizing the rod aerodynamic shape, adding deflector structures, etc.
SUMMARY
Existing research shows that when the train speed is greater than 300 km/h, the proportion of aerodynamic noise source energy to total noise source energy . . .
