일단 고정된 STS304, SS400의 ESPI법을 적용한 진동해석

Analysys of Vibration on STS304, SS400 Rectangular Plate with One Parallel Side Fixed

Today, many devices are being made small but competent in various designs. The inevitable vibration from these devices affects not only design variable and life of the system but also human body and its surroundings. To investigate the vibration patterns, we fixed one side of STS304 and SS400 flat boards that are used for the external material of various devices, and measured the changes of vibration according to the frequency change, with ESPI law, the optical vibration measuring method.
