A Semi-Analytical and Semi-Numerical Method for Acoustics Radiation Characteristics of Rotational Shells

Article Preview

Abstract:

A semi-analytical and semi-numerical method is presented for analyzing the acoustics radiation characteristics of a rotational shell. Combining the dynamics control equation and the sound pressure expression, the vibro-acoustics equation of the rotational shell is formulated firstly. Then, a semi-analytical method is developed based on the superposition principle. The comparisons with the document show that the proposed method is accurate and efficient.
