A Study on the Vibration Mode Measurement of Rectangular Plate with Two Parallel Sides Fixed by Electronic Speckle Pattern Interferometry

전자처리 스페클 간섭법에 의한 양단이 고정된 직사각형 평판의 진동모드 측정에 관 한 연구

In the word, there is varied types of vibration, and these affect the mechanical industry. In this paper is plates with two parallel sides fixed. Electronic speckle pattern interferometry (ESPI) is one of the optical nondestructive testing technique. By using the ESPI, vibration modes for excitation point, a/b(ratio of longuitudinal and lateral length), and kind of specimen are measured and compared qualitatively with theoritical analysis that Warburton proposed.
