FEA and CFD simulations can be used in Aeroacoustics and Vibroacoustics to analyze the noise and vibration characteristics of aircraft and aerospace systems. These simulations can help engineers to optimize the design of aircraft components and systems for noise and vibration reduction, and to comply with the regulations and standards set by the industry and the government.
In Aeroacoustics, FEA simulations can be used to analyze the structural response of aircraft components to acoustic loads, such as turbulence, jet noise, and airframe noise. CFD simulations can be used to analyze the flow-induced noise generated by the interaction of the airflow with the aircraft surfaces. These simulations can help to identify the sources of noise and to develop noise reduction strategies, such as the use of acoustic liners or the optimization of the airframe shape.
In Vibroacoustics, FEA simulations can be used to analyze the structural response of aircraft components to vibration loads, such as engine vibration or rotor blade vibration. CFD simulations can be used to analyze the aerodynamic loads on the aircraft surfaces that can cause vibration. These simulations can help to identify the sources of vibration and to develop vibration reduction strategies, such as the use of active vibration control or the optimization of the mechanical systems.
