Dynamic Analysis of a Deploying Beam with Geometric Non-Linearity and Translating Acceleration

기하학적 비선형과 이송 가속도를 갖는 전개하는 보의 동적해석

The dynamic response of an axially deploying beam is studied when the beam has geometric non-linearity and translating acceleration. Based upon the von Karman strain theory, the governing equations and the boundary conditions of a deploying beam are derived by using extended Hamilton's principle considering the longitudinal and transverse deflections. The equations of motion are discretized by using the Galerkin approximate method. From the discretized equations, the dynamic responses are computed by the Newmark time integration method.
