Facing an increasingly competitive, threat-filled environment, aerospace and defense companies must digitally transform their processes and products to deliver radical innovation and maintain market leadership.
Prediction of vibration and sound propagation can play important roles in the design of many products. Examples include noise caused by turbulent flow around structural components, transmission of sound through thin panels and the acoustic performance of piezoelectric devices, etc. Excessive vibration can reduce the fatigue life of aerospace components. Excessive noise levels are the biggest threat in deploying defense equipment on the field.
Virtual assessment of vibration, impact and acoustic performance of products early in the design stage can greatly reduce cost and product development time. Join us to learn about Ansys solutions for vibration and acoustic simulations.
In this session we will discuss on the following topics:
Aeroacoustics modeling approaches
High-speed flow aero-acoustics modelling examples
Validation studies for high-speed flow aeroacoustics
Sound radiation due to vibrating structures
Different techniques to predict noise in low, mid and high frequency ranges
Diffuse sound-field acoustics
Coupling between flow pressure (CFD)/electromagnetic forces and vibro-acoustics
Coupling between MEMS and acoustics for sensor application
Examples to be Discussed
Acoustics Induced Fatigue to Aerospace Structures
Prediction of Windshield Noise
Prediction of Electric Motor Noise
Computation of stresses caused by unsteady flow pressure fluctuations on a blade using TBR methods in Ansys CFX. The information is then mapped to the blade geometry in Ansys Mechanical where stresses are determined.
Who should attend?
