摘要

针对熔盐储罐在运行过程中因液位变化和温度波动导致的罐壁应力集中问题，开展热力耦合作用下的结构评估与优化研究。首先，基于有限体积-有限元耦合方法，建立熔盐储罐的热力学耦合模型，通过多物理场仿真分析不同液位工况下罐壁温度场、应力场及变形场的分布特性；其次，结合模拟结果识别关键失效风险区域；最后，提出针对性优化方案并验证其有效性。模拟结果表明：液位变化导致储罐温度呈现显著分层现象，罐壁最大温差达8℃；在热力耦合作用下，罐壁应力随液位的升高而增大，最大应力为105MPa，且集中于第1、2层罐壁区域；拱顶部位因受热膨胀约束最小，变形最为显著，最大变形可达0.16m，而罐壁其他区域需保持热变形自由状态以避免附加应力；通过局部布置加强筋优化结构设计后，危险点应力降幅达38%，有效改善了结构的力学性能。该研究可为熔盐储罐的设计优化与安全运行提供理论支撑。

Abstract

To address the stress concentration issues inmolten salt storage tank walls caused by liquid level variations and temperature fluctuations during operation

structural evaluation and optimization research are conducted under thermo-mechanical coupling effects. First

a thermomechanical couplingmodel of themolten salt storage tank is established using a finite volumefinite element coupledmethod. Multi-physics simulations are employed to analyze the distribution characteristics of the temperature field

stress field

and deformation field in the tank wall under different liquid level conditions. Subsequently

key failure risk areas are identified based on simulation results. Finally

targeted optimization schemes are proposed

and their effectiveness is validated. Simulation results indicate that liquid level changes lead to significant temperature stratification in the tank

with amaximum temperature difference of 8℃ in the tank wall. Under thermo-mechanical coupling effects

the wall stress increases with rising liquid levels

peaking at 105MPa

primarily concentrated in the first and second layers of the tank wall. The dome area exhibits themost pronounced deformation due tominimal thermal expansion constraints

with amaximum deformation of 0.16m

while other regions of the tank wall require thermal deformation freedom to avoid additional stresses. By locally arranging stiffeners to optimize the structural design

the stress at critical points is reduced by 38%

effectively improving themechanical performance of the structure. This research provides theoretical support for the design optimization and safe operation ofmolten salt storage tanks.
