摘要: 文章研究了結(jié)構(gòu)在高聲強(qiáng)噪聲環(huán)境下的聲振響應(yīng)特性,給出了一種以試驗數(shù)據(jù)為基礎(chǔ)的響應(yīng)外推方法,與線性外推方法進(jìn)行了比較,并研究了結(jié)構(gòu)在高聲強(qiáng)噪聲環(huán)境下結(jié)構(gòu)弱非線性特性。Abstract: This paper investigates vibro-acoustic response characteristics of structures under high sound intensity, presents a response extrapolation method based on experimental data and the results of linear extrapolation, and discusses weak nonlinear characteristics of structures under high sound intensity environment.
