The aeroacoustics of rail vehicles is an important challenge, for the comfort of passengers, residents and for public health.

There are various sources of noise in a train: the bearing, the booster units, etc. Through simulation, Zelin assists you in the identification of sources of aerodynamic noise and the aeroacoustics optimization of the rail vehicle. Some examples include:
• Modeling of the entrance into tunnels
• Identification and characterization of noise sources (bogie area, pantograph, air intakes…)
• Better positioning of external elements
• Optimization of shapes for the reduction of noise
