NVH Webinar - Hybrid CAE NVH Simulation & Test Approach for Optimizing Acoustic Performance

Advances in NVH and Acoustics Virtualization to Maximize Product Reliability, Quality, and Sustainability

Abstract:
Prediction of structure-borne noise and sound propagation can play important roles in the design of many products. Examples include noise caused by vibrating structural components, transmission of sound through thin panels and the acoustic performance of piezoelectric devices. Solving these types of acoustic wave propagation problems (and many more) can be performed in a coupled way, in which the fluid and structural domains are solved simultaneously, or in an uncoupled way, in which the structural analysis is performed first, followed by the acoustics analysis.

Prediction of acoustic performance of products early in the design state and fine-tuning acoustic characters of the final marketable product is increasing important factor for the competitive edge in the design of many common products and structures including speakers, cars, planes, buildings, sonar, and machinery. To save time and costs associated with improving acoustic performance of the product during product development cycles, modeling and simulation has become essential. Combining data from test and simulation helps engineers to understand and optimize system level acoustic performance.
