摘要
本文讨论了当其几何、物理参数以及两端支承方式关于跨度中点为对称时杆、梁离散系统所特有的振动特性,指出具有对称性的杆、梁离散系统可以分解为两种相应不同支承条件的半边结构。在此基础上可以提出并求解相应离散模型的频率反问题。
This paper discusses characteristic vibrating properties for a symmetric rod and/or beam in which the geometric and the physical parameters are symmetric distribute about midpoint of the structure. It is pointed out that a symmetric rod and/or beam can be resolved into two half a structures with different supported form in this paper. These results are foundation raised and solved inverse vibration problems for the symmetric structures.
