摘 要: 本文充分考虑了各种影响因素,采用理论分析和实验研究相结合的方法,得到了U型管管束固有频率的计算公式。实验结果表明,该公式的误差,一般在±8%以内,满足工程设计要求。另外,本文提供了相应图表,使工程设计简单方便。 On the basis of the theoretical analysis and experimental investigation,a theoretical formula to colculate the natural frequency of varied U bundle is presented. The experimental results show that the deviations of this formula are within the range of ±8%,given in the form of charts and data,are appeicable and can meet the requirement of engineering design.
