Содержание слайда: Modal analysis
The purpose of performing a modal analysis is to find the natural frequencies and mode shapes of a structure. If a structure is going to be subjected to vibrations, then it is important to analyze where the natural frequencies occur so that the structure can be designed appropriately.

№26 слайд![Harmonic analysis - Full A](/documents_6/2ed64932abffe857dd655ec85df0c6ed/img25.jpg)
Содержание слайда: Harmonic analysis - Full
A harmonic analysis finds the steady state response of a structure under sinusoidal loading conditions. A harmonic, or frequency-response, analysis considers loading at one frequency only. Loads may be out-of-phase with one another, but the excitation is at a known frequency. This procedure is not used for an arbitrary transient load.

Содержание слайда: Conclusion
ICS is an exceptional method of generating radiation of high brilliance, its development is important for National security and a number of other applications.
Designing of ICS interaction region is a complicated process that comes in several interconnected stages.
Present design is a trade-off between technical requirements of finesse, size, mechanical stability and overall complexity. It has its limitations.
