重水箱内壁热—机耦合应力分析

Thermal-mechanical stress analysis of heavy water tank interior wall

用有限元方法对重水箱内壁的有肋和无肋两种模型作了热—机耦合应力研究 ,并对结果作了充分和合理的分析 ,最终得到了重水箱内壁加肋必要性的结论。

In the paper,the formula of boundary and initial conditions in thermal stress analysis are described.The uses sub-program to realize the uneven thermal loads is clarified and the process diagram is illustrated.The data of displacement and stress of two FEM models thermal-mechanical analysis are studied.The necessity in rib adding is demonstrated.
