Study on the Dynamic Deformation Characteristics of a Cantilever Beam Undergoing Impulsive Force Using Wavelet Transformation

웨이블렛 변환을 이용한 충격력을 받는 외팔 보의 동적 변형 특성 연구

Dynamic response characteristics of a beam undergoing impulsive force are investigated using the wavelet transform method in this study. When an impulse is applied to an arbitrary position of a beam, it will generate a structural deformation wave. The characteristics of the wave are changing in the domain of time and space. The maximum amplitude of each natural frequency mode and the time to reach the maximum amplitude are obtained in this study. The effects of the location of impulse on the variations of the dynamic characteristics is also investigated.
