Standing Wave Calculation by Acoustic Simulation Tool

Comparison with Analytical Solution

Abstract

Many industrial automotive or aerospace applications involve the analysis of the sound propagation, either radiated by vibrating structures or induced by a flow. Numerical simulation can be used as an efficient and robust alternative to experimental prototyping for both analysis and design. The finite element method has been widely used for tackling such NVH problems. In this paper, acoustic analysis originated by Lighthill’s analogy, mechanism of standing wave, calculation results of acoustic analysis tool ACTRAN, and comparison with analytical solution are reported.
