摘　　要：基于流体及储罐动力相互作用理论,建立与微分方程初值问题等价的积分表达式,推导得出储罐-流体相互作用体系特征方程和动力响应求解公式。在此基础上,采用面向对象的VB与Fortran混合编译方法,基于VB的GUI对主界面和数据输入窗口进行设置,通过菜单编译器及多窗体的耦合实现菜单名称设置及窗口调用功能,开发了一款立式圆柱形储罐动力有限元分析程序PSAST V1.0。同时利用该程序对储罐-流体相互作用体系进行振动模态及地震作用下的动力响应分析,通过与ADINA计算结果及解析解对比,验证了本文所开发有限元程序应用于储罐-流体相互作用体系动力分析的准确性和可靠性。Based on the coupled dynamic interaction theory of fluid and tank,an integral expression equivalent to the initial value problem of the differential equation is established,and the characteristic equation and dynamic response formula for tank-fluid interaction system are derived. Based on the object-oriented VB and Fortran hybrid compiling method,a visualized program for dynamic analysis of an anchored cylinder liquid storage tank PSAST V1.0 is developed by setting the main interface and input windows in terms of VB GUI,which implements the primary function of calling subroutines.Furthermore,the program is employed to analyze the vibration mode and dynamic response of a tankfluid interaction system under earthquake. By comparing with ADINA calculation results and analytical solutions,the accuracy and reliability of the developed program in this paper for dynamic analysis of the tank-fluid interaction system are verified.
