Study on Finite Simulation Technology for Seal Ring of Reactor Pressure Vessel
-
摘要: 借助ANSYS的非线性等向强化本构模型,对反应堆压力容器O形密封形环的弹塑性进行有限元模拟。通过密封环3种模拟方式(均布压力、弹簧单元、三维实体)得到的反应堆压力容器分离量结果并进行对比,发现三维实体模拟方式能够有效地降低分析的过余保守性,提高密封分析计算结果精度。Abstract: Elasto-plastic analysis for the seal ring of reactor pressure vessel was done by nonlinear isotropic hardening constitutive model using ANSYS. The results of separating were obtained by three simulation means including uniform stress, spring elements and three-dimensional solid. The third way can reduce the excessive conservative part of the results effectively and improve the precision of sealing analysis.
