NON-TOUCH PROPER VIBRATION CHARACTERISTICS MEASUREMENT DEVICE

摘要

PURPOSE: A non-contact type apparatus for measuring the proper vibration characteristic of a structure is provided to easily perform measurement by spacing the measuring unit from the structure. CONSTITUTION: A non-contact type apparatus for measuring the proper vibration characteristic of a structure includes a vibration applying unit(10), a measuring unit(20), and an analyzing unit(30). The vibration applying unit applies vibration to a structure(100). The measuring unit is spaced apart from the structure and measures a signal including the proper vibration of the structure. The analyzing unit obtains the measured signal and transforms the signal into a frequency form.
