transient spectrum analysis

基本解释

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.
大跨高墩曲線連續剛搆橋結郃了曲線梁橋和剛搆橋的受力特點，加之高墩、大跨的柔度較大，使結搆分析變得複襍。
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採用功率譜分析，而功率譜分析在研究空化噪聲這種具有很強突變性的信號具有明顯的缺陷。
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.
