防振条对蒸汽发生器U形管动态特性影响研究
Research of Influence of Anti-vibration Bars on Dynamic Characteristic in SG U-tubes
【摘要】 应用ANSYS参数化设计语言对蒸汽发生器(SG)U形管流体结构耦联系统动态特性进行了数值模拟,着重考虑了防振条对U形管固有频率的影响.对U形管在空气中和水中的固有振动特性做了比较,并用统计回归给出了半经验公式.
【Abstract】 The fluid-structure interaction dynamic characteristic of steam generator U-bend tube is simulated by using ANSYS parametric design language,focusing on the influence of the anti-vibration bars of the U tube.Also the dynamic characteristics are compared when the tube is in the air and submerged in water.The empirical formulae are presented based on the numerical simulation results.
