transient spectrum analysis

基本解釋

In this thesis, the spectrum analysis and transient analysis of curved continuous rigid-frame bridge with high piers and long spans under seismic excitation are performed.
大跨高墩曲線連續(xù)剛構(gòu)橋結(jié)合了曲線梁橋和剛構(gòu)橋的受力特點(diǎn)，加之高墩、大跨的柔度較大，使結(jié)構(gòu)分析變得復(fù)雜。
Power Spectrum analysis is always used in spectrum analysis of cavitation noise. However, it is obviously unfit for research on the transient signal such as cavitation noise.
空化噪聲的譜分析一般采用功率譜分析，而功率譜分析在研究空化噪聲這種具有很強(qiáng)突變性的信號(hào)具有明顯的缺陷。
Based on practical experience, the paper summarizes such problems as transient dynamic analysis, mode analysis and spectrum analysis and their solutions to be used by ANSYS engineers for reference.
結(jié)合使用經(jīng)驗(yàn)，總結(jié)了基于通用有限元軟件ANSYS進(jìn)行瞬態(tài)動(dòng)力分析、模態(tài)分析、譜分析等動(dòng)力分析的有關(guān)問(wèn)題及解決方法，可供使用ANSYS的工程技術(shù)人員參考。
