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.
大跨高墩曲线连续刚构桥结合了曲线梁桥和刚构桥的受力特点，加之高墩、大跨的柔度较大，使结构分析变得复杂。
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.
空化噪声的谱分析一般采用功率谱分析，而功率谱分析在研究空化噪声这种具有很强突变性的信号具有明显的缺陷。
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.
结合使用经验，总结了基于通用有限元软件ANSYS进行瞬态动力分析、模态分析、谱分析等动力分析的有关问题及解决方法，可供使用ANSYS的工程技术人员参考。
