【摘要】 利用ANSYS软件包对某研究堆冷中子源(CNS)的冷包在内外压共同作用下的强度进行分析。分析结果表明,冷包的原设计不甚合理,冷包的局部应力超过了设计应力。变更原结构的几何尺寸后进行了进一步计算分析,并提出了相应的补强方案。改进后冷包的计算结果表明,补强后的结构很好地满足设计要求。研究结果为冷包的实际工程设计提供了依据。更多还原

【Abstract】 The strength of the moderator cell of cold neutron source(CNS) was analyzed under internal and external pressure.The analytical results show that local stress exceeds design stress,and original design of the moderator cell isn’t reasonable.The structure dimension of original design was revised,and the revised structure was analyzed and optimal project was proposed.The reinforced structure of moderator cell can meet the design requirement well. Therefore,the project provides valuable reference for factual design in engineering.更多还原
