摘要

摘要: 采用测量转动惯量的方法对核电厂安全壳地坑过滤器水下附加质量进行测量,分别测量了圆柱、圆筒、双层圆筒、圆筒形地坑过滤器4种结构。将圆柱的附加质量测量值与在理想流体中的理论值进行对比,验证了该方法可以比较准确地测量附加质量。结果分析表明,附加质量不随激振频率变化,圆筒结构附加质量为圆柱结构的1.9倍,双层圆筒附加质量与单层圆筒差异不大;地坑过滤器由于表面开孔附加质量较圆筒结构降低70%;地坑过滤器附加质量与本身质量的值为同一数量级,地坑过滤器设计时不能忽略附加质量。

Abstract: This paper investigates the experimental method to measure the added mass of the contain-ment sump strainer in nuclear power plants using the inertia moment measurement.Four types of structures,i.e.,solid cylinder,thin-walled cylinder,double-walled cylinder and sump strainer,are tested in the experi-ment.The added mass of the solid cylinder tested in the experiment is compared with the theoretical value,and it is proved that the method in this study is with high accuracy in testing the added mass.The results ex-hibit that the added mass of thin-walled cylinder increases 1.9 times compared with the solid cylinder,and small difference appears in the values of added mass between single-walled and double-walled cylinders.The added mass of sump strainer decreases 70% compared with the thin-walled cylinder because of the opening in the cylinder surface.However,the added mass of sump strainer is similar with the mass in magnitude,so that the added mass can not be neglected when designing the structure
