在简要概述了统计能量分析法和相似结构外推法的基础上,可以看出:统计能量分析法已经成为高频声振环境结构响应预示的主要方法,而相似结构外推法因其简单易用且适用于全频域范围的特点,仍然应用于声振环境响应预示。分别利用两种方法对飞行器整流罩简化模型的声振环境响应进行了分析。最后通过对计算结果的对比分析,对外推法的缺陷进行了探讨。
Based on a brief overview of statistical energy analysis and similar structure extrapolation, it can be seen that statistical energy analysis has become the main method for predicting the response of high-frequency vibra- tional environments. However, the extrapolation of similar structures is simple and easy to use Applicable to the characteristics of the full range of frequency range, is still used to predict the response of acoustic vibration. Two kinds of methods are respectively used to analyze the vibration response of aircraft fairing simplified model. Finally, through the comparative analysis of the calculated results, the defects of the extrapolation method are discussed.
