| 摘 要： | 研究有限均匀欧拉梁结构的振动响应。梁结构包括单跨梁和具有中间支座支撑的多跨梁结构。采用波动分析法来分析梁结构的振动响应。梁的边界条件采用边界阻抗来定义,建立了求解标准边界条件下有限梁结构在简谐外力激励时响应的统一方程,为分析计算具有标准边界条件的梁结构振动响应奠定基础。

| Abstract: | This paper studies the vibration response of finite uniform Euler girder structures which including continuous girder and multispan girder with intermediate support. The girder vibration response is analyzed by wave analysis method,and the boundary conditions are defined by boundary impedometer. Under standard boundary conditions, unified equations for solving the response of finite girder structure to simple harmonic excitation have been built up. It provides a basis for the calculation of girder vibration response under standard boundary conditions. |
