Slender structures show widely spaced modes, while squat structures exhibit closely spaced modes.
These resonant frequencies can be identified from ambient-vibration measurements โ with just a few minutes of recording.
๐ง๐ฟ๐ผ๐บ๐ถ๐ป๐ผ and ๐ฆ๐๐ฟ๐ถ๐ฐ๐ฎ๐ make this type of structural dynamic characterization particularly simple: small 3-component instruments, no artificial excitation, and a lot of information hidden in ambient vibrations.
