| 摘 要： | 板式塔在工作状态下,塔体受到横向载荷作用时,塔板发生倾斜,板上介质的液面仍保持水平,塔板上介质的质心将偏离塔体的轴线.每一层塔板上介质质心的变化都对塔体产生附加的偏心载荷,附加的载荷加剧了塔顶的挠度.推导了介质重心的偏心矩公式并利用力学的叠加原理和自编的计算程序,得到附加的偏心载荷对塔顶产生的附加挠度.分析和计算的结果...

| Abstract: | The column plate inclines when the tray column is subjected to lateral loads under operating conditions.The gravity centre of liquid on the column plate deviates from the axis of the column,because the liquid level on the column plate keeps in horizontal.The change of the gravity centre of liquid on every column plate produces additional eccentric loads that may intensify the top deflection of tray column.The formula of eccentricity of the gravity centre of liquid was deduced.Using superposition principle o... |
