基于Ansys的铀离子交换塔模态分析
|
摘要
利用Ansys软件建立铀离子交换塔的有限元计算模型,计算铀离子交换塔的前10阶固有频率,给出三维主振型图。各阶振型的x向、y向最大应力及主要变形均发生在铀离子交换塔体下沿与支柱交界处,说明由于振动产生的铀离子交换塔体破坏容易发生在塔体下沿与支柱交界处,因此铀离子交换塔体下沿与支柱交界处的抗震加固非常重要,抗震加板应靠底部设置。
Ion exchange towers are exposed to serious damage in the event of earthquakes.It is very necessary to study the seismic resistance of ion exchange tower. A finite element model of anchored ion exchange tower was made by Ansys. The first 10 ranks of inherent frequencies were made out, and three-dimensional main vibratory model figures were drawn out. The maximal stress along x-axis and y-axis and the main displacement were found at the bottom part of the wall of tower junction with the pillars. It is concluded that the breakage of tower wall easily occurs at the bottom part of the wall of tower junction with the pillars. Therefore, it is very important to reinforce the junction of the tower body, and the strengthening plate should lie near the bottom of wall.
