利用有限元分析软件ANSYS对这种结构进行模态分析，得到其共振频率和一阶振动图；

Then the new structure is simulated with modal analysis by finite element analysis software ANSYS, and the resonant frequency and the first vibration map are presented.

振动图是用来记录地面随时间运动并且是地震学家用来研究地震波的基础数据。

Seismograms are recordings of ground motion as a function of time and are the basic data which seismologists use to study the waves generated by earthquakes.
