摘　　要：在工业体系不断壮大的今天,石油与天然气行业的发展也不断的在随着时代潮流发展,而液体储罐在其中起着至关重要的作用。但重要的同时他们也同样危险,一旦受损就可能让我们的经济与环境遭受到巨大的损失与灾害。作为工业发展中如此重要的一部分,其抗震安全性至关重要。主要介绍无挡板储罐对其震荡参数的影响,还概述了以晃动频率,对流体压力和动水压力脉冲形式预测晃动参数的数学公式。同时,简要介绍ANSYS软件对无挡板圆形储罐进行建模的假设以及寻找到较为适合网格大小。本研究得出必须要用网格尺寸为20×20最佳尺寸用来确定参数,细化网格尺寸为5×5会使得出的解不够精确。Today,with the growing industrial system,the oil and gas industry is also developing with the trend of the times,and liquid storage tanks play a vital role in it.Once damaged,our economy and environment may suffer great losses and disasters.As such an important part of industrial development,seismic safety is crucial.In this paper,the influence of baffleless storage tank on its oscillation parameters was introduced,and the mathematical formula for predicting the sloshing parameters in the form of fluid pressure and hydrodynamic pressure pulse with sloshing frequency were also summarized.At the same time,the assumptions of ANSYS software for modeling the circular tank without baffles were introduced,and the units suitable for modeling were found out.In this study,it was concluded that the detailed optimal size of 20×20 must be used to determine the parameters.Thinning the grid would make the solution not accurate enough.
