【摘要】 利用ANSYS有限元分析软件,对五种截面的角钢悬臂梁进行了模态分析,然后在简谐荷载作用下进行谐分析,获得五种角钢悬臂梁的在各节点的位移响应图,结果表明:各节点在不同频率下的变形情况,为工程中解决角钢悬臂梁的振动问题提供参考。更多还原

【Abstract】 By using the finite element software ANSYS we carried out modal analysis on the five cross-sections of angle cantilever beam.In the harmonic loads we conducted harmonic analysis,and then obtain displacement response graphs of five angle cantilever beams in each node,analysed and discussed the deformation of each node at different frequercy,this will provide a reference for vibration problem of angle cantilever beam.更多还原
