Learn what normal modes analysis is.
- [Instructor] In this video,…we're going to look at the background to normal modes analysis.…So what exactly is normal modes analysis?…Now, there are various terms used…to describe a normal modes analysis,…and this can be a bit confusing.…We talk about an eigenvector analysis,…sometimes it's called an eigenvalue analysis,…a natural frequency analysis.…The terminology, as I said, can be very confusing.…So the objectives of the analysis,…it's all the same type of analysis,…we are trying to find all…the resonant or natural frequencies within a range.…
Now, these natural frequencies…are defined in cycles per second or hertz,…or sometimes radians per second or radian per second.…We need to find mode shapes corresponding…to each natural frequency.…Now, one of the important things…to understand is these are just shapes coming…from a normal modes analysis.…There's no units, and there is actually no…amplitude associated with them.…Now, when we are doing normal modes analysis,…we balance the two internal energies…to look for these natural frequencies.…
