在反应堆中存在着许多类似圆柱体并处于横向流中的部件,可能存在强烈的流体激励机理,因此在疲劳以及腐蚀、磨损设计中一定要考虑到相应的响应。研究了振动激励机理的升力分量及其升力谱密度的特性及其影响因素以及升力方向与阻力方
There are many cylinder-like and cross-flow components in the reactor. There may be a strong fluid excitation mechanism, so fatigue and corrosion, wear design must take into account the corresponding response. The characteristics of the lift component of the vibration excitation mechanism and its lift spectrum density and its influencing factors as well as the relationship between the lift direction and the resistance
