Join Tony Abbey for an in-depth discussion in this video Introduction to normal modes analysis, part of SOLIDWORKS Simulation: Dynamic Analysis.
- [Instructor] In this video, we're going to look at…an introduction to normal modes analysis.…And the very first question is,…what is normal modes analysis?…Now we find there's quite a few terms used…to describe the same thing.…We find we've called it eigenvector analysis,…eigenvalue analysis.…SOLIDWORKS calls this a frequency analysis.…The terminology can be very confusing.…One way to clear up the confusion…is to look at the objectives of the analysis.…The first objective is to find all the resonant…or natural frequencies within a range.…
And these are defined in cycles per second or hertz,…or occasionally in radians per seconds or rad per second.…The second objective is to find the mode shapes…at each natural frequency.…Now these are only shapes.…There's no actual unit involved, and there's no amplitude.…Because we're not applying a force input,…so we can't get a scaled response coming out.…We saw in the previous video…that the full equation of motion was defined…by an internal energy balance.…
We do a similar kind of thing for the natural frequencies.…
