Abstract

Summary

Differential Acoustic Resonance Spectroscopy(DARS) has been proposed to measure the acoustic properties of a small sample in low frequency range(about 1 kilohertz). For a new method, it is important to verify the correctness of these assumptions and the properties estimation method, but it can not be realized by physical experiment itself. In this paper, we simulate the measurement process based on the elastic wave equations in cylindrical coordinates, and analyze the assumption in the DARS theory derivation. By the numerical research, we also verified the feasibility of estimating the compressibility and density of the sample simultaneously.
