球形储罐是石油化工行业最常用的设备之一，其存储物质具有易燃、易爆、剧毒、腐蚀等特性。地震荷载作用下球形容器（球罐）抗震安全保障问题已经成为特种设备抗震研究中重要的课题之一。基于ANSYS有限元软件，首先建立典型球罐力学模型，通过地震波激励下精确的时程反应分析，确定应力显著发生的位置；其次，分析球罐支撑结构设计参数（支柱数目、直径，拉杆直径等）对球罐抗震性能的影响；最后，选取几种典型的大、中、小型球罐，明确各类球罐的抗震性能。该研究为球罐抗震安全保障及设计提供合理依据。

The spherical tank is one of the most commonly used equipment for petroleum and chemical in-dustry.The storage material in the tanks is flammable,explosive,toxic,corrosive and other characteristics. The seismic safety problem of the spherical tank under seismic load has become one important subject in seismic research of special equipment.Based on the ANSYS finite element software,typical spherical tank mechanics model is established first of all,through precise time history response analysis under the seis-mic excitation to determine the significant location of the stress.Then,the seismic performance impact of the support structure design parameters,such as the diameters and the numbers of the support columns, the diameters of the tie-rods,and the volume of the tank,is analyzed.Finally,the seismic performance of all kinds of spherical tank,such as the large,medium and small tank,is determined.It provides a reasona-ble basis for the anti-seismic safety security and design of the spherical tank.
