modal testing

Modal testing is a process used to analyze how a structure or object naturally vibrates when it's disturbed, such as by tapping or shaking it. By measuring these vibrations, engineers can identify its natural frequencies, modes of vibration, and how it responds to different forces. This information helps determine the structure’s health, design improvements, or potential issues. Think of it like studying how a musical instrument vibrates to produce sound, but applied to buildings, bridges, or machinery to ensure safety and performance.
