摘要
CAP1400反应堆堆内构件为原型类堆内构件。为了验证CAP1400反应堆堆内构件的结构的完整性和堆内构件流致振动评价提供依据,有必要进行反应堆堆内构件流致振动模拟试验。堆内构件流致振动模拟试验通常采用缩小比例的比例模型。模型比例、模型相似关系和模型简化设计是模拟试验的重要组成部分。对模型比例主要考虑因素、比例模型遵守的相似关系及主要模拟试验试验件简化设计进行了详细的描述。试验件的简化不仅能降低模拟试验的制造成本,而且能获得相对准确的实验数据。
While the first CAP1400 reactor internals is defined as a ＂prototype＂ , it is necessary to carry out the reactor internals flow-induced vibration simulation test for verifying the structure integrity of reactor internals and providing data for vibration assessment of CAP1400 reactor internals. The reactor internals flow-induced vibration simulation test is usually a reduced scale model test. This paper describes in detail the main factors of model scale, similarity criterion and the simplification of test model. The simplification of model will not only reduce the fabrication cost, but also obtain more accurate test data from the flow-induced vibration simulation test.
