아접선력을 받는 보의 동적안정성에 미치는 고유치 감도해석 = Eigenvalue Sensitivity on Dynamic Stability of Beams Subjected to Subtangential Forces

다국어 초록 (Multilingual Abstract)

This paper deals with the eigenvalue sensitivity of a finite element formulation on vibration and dynamic stability of an elastically restrained cantilevered beam under subtangential forces. Governing equations are derived by energy expressions using extended Hamilton's principle. In order to more quickly and efficiently obtain the critical subtangential force for a given system, a technique which utilizes the eigenvalue sensitivity with respect to the system parameter is introduced. More accurate results are obtained for both variations in the spring position, spring stiffness, as well as the subtangential parameter.
