边界条件对短梁结构有限元分析影响的研究
Study on the influence of boundary conditions on the finite element analysis of short beam
摘要
Abstract
Beam structure is widely employed in engineering applications .Its supporting conditions can not be easily dealt with as ideal fixed or simply supported ones in practice .The dynamics of a short beam under hybrid-boundary conditions was served as the study object .Modal analyses of short beam structure under different boundary conditions were performed by utilizing the finite element analysis software of Abaqus .Results show that the boundary condition can change the system stiffness ,and alter the structure modal characteristics .The modals of short beam vary from the boundary conditions .The analyzed modal frequencies of short beam under mixed bound-ary conditions consist well with the modal experiment results .关键词
