摘要
在主泵激励下,反应堆一回路辅助系统管道存在振动过大问题,而振动传递到安装基础会带来严重的安全隐患。为解决该问题,需要开展辅助系统管道振动控制研究。首先建立辅助系统管道的有限元模型,使用优化算法对管道吊架的位置进行优化,然后采用试验方法,对优化前后吊架固定端的振动进行讨论分析,在此基础上,通过加装动力减振器(DVA)的方式进一步降低通过吊架传递到基础上的振动,最终得到管道振动控制优化方案,为后续的减振优化设计提供借鉴。
Under the excitation of the pump, the pipes of auxiliary system for primary loop have a problem of excessive vibration, and when the vibration is transmitted to the installed base, it may result in serious troubles. To solve this problem, the study on piping vibration control of auxiliary system needs to be carried out. First of all, the finite element model of the pipe for auxiliary system is established and the positions of the supports of the pipe are optimized using the optimization algorithm. Then, using the test method, the analysis on the vibration of the fixed end before and after optimization is carried out. On this basis, the vibration transmitted from the support to the installed base is reduced with Dynamic Vibration Absorber(DVA). Finally, the optimization scheme of vibration control of the pipe is obtained. And it offers some references for the optimization design of vibration attenuation.
