振动台台面动力特性的有限元分析

FINITE ELEMENT ANALYSIS OF THE DYNAMIC CHARACTERISTICS OF THE TABLE-BOARD

利用大型有限元分析软件 ANSYS 对结构实验室在建的振动台台面进行了有限元分析,得到了台面的自振频率和模态。分析结果表明:在使用频率范围内可以保证振动台的实验性能。

Table-board a building in the structure laboratory can be analysed using finite element analysis software ANSYS, the frequency and the model are calculated. As a result ： The performance of the table can be assured in the using frequency scope.
