Study on Application of Green’s Function Method in Thermal Stress Rapid Calculation

摘要: 通过对格林函数在热应力分析中的应用研究,得到一种结合有限元分析和数值计算进行热应力快速计算的格林函数方法。以核电厂主管道安全注入接管在升温和降温瞬态下的热应力分析为算例,验证该方法的合理性和准确性。同时对比分析格林函数法和有限元分析法的优缺点。

Abstract: This paper presents a quick and accuracy thermal stress calculation method,the Green’s Function Method,which is a combination of finite element method and numerical algorithm method.Thermal stress calculation of Safe Injection Nozzle of Reactor Coolant Line of PWR plant is performed with Green’s function method for heatup and cooldown thermal transients as a demonstration example,and the result is compared with finite element method to verify the rationality and accuracy of this method.The advantage and disadvantage of the Green’s function method and the finite element method are also compared.
