摘要：

The modulus of elasticity of spheroids can be estimated by the analysis of their proper free vibrations, and can be used for the evaluation of fruit maturity and/or ripening. The lowest frequency resonant peak (mode M(o)) was previously proposed as a basis for corrections of the whole amplitude-frequency plot in relation to the forcing deformation level. This paper describes a computing method that makes it possible to incorporate M(o) peak self-changes into the correction. The exact solution is given for parabolic and/or parabolic-like peaks. It is shown that improving the correction process is important mainly for wide peaks. The methods of making precise corrections of amplitude-frequency plots in case of general, not parabolic, M(o) peaks are also given. (c) 2007 IAgrE. Published by Elsevier Ltd. All rights reserved.
