摘要
运用有限元分析软件ANSYS对储罐参数化建模,通过模态分析确定储罐的一阶固有频率,根据设备一阶频率的计算结果,确定储罐的x、y、z三个方向的地震加速度,利用准静力法对设备进行抗震计算,用来校核储罐的强度。计算结果对储罐的结构设计有实际意义,明确反映出在地震状况下储罐的结构安全性。
Finite element analysis software is used to determine the natural frequency of the tank. The first order natural frequency which is obtained by modal analysis is used to determine the x, y, z seismic accelertaion. Seismic calculation is used to check the strength of the tank based on the pseudo-static analysis method. The result has practical references fot the tank structure design, and can clearly reflect the safety of the tank under the earthquake condition.
