摘要
接受积分法可用于计算结构在随机载荷作用下响应的均方根。本文研究了接受积分法的理论基础和适用条件,并将该方法与有限元方法相结合,简化了该方法的计算过程,使该方法更易于实现。基于反应堆吊篮缩比模型试验获得的流体脉动压力,采用接受积分法与有限元方法相结合的方法计算了吊篮结构的流致振动响应,计算结果与试验结果吻合良好。
The acceptance integral approach is applicable for calculating the root mean square of structure response under random loading.The theoretical basis and application conditions of the acceptance integral approach were studied,and the approach was combined with the finite element method to simplify the calculation process and also make it easy to implement.The flow-induced vibration responses of the core barrel were calculated using the combined method and the test values of the fluid fluctuating pressure of scaled model test of core barrel.The calculation results are consistent well with the test ones.
