| 摘 要： | 一负压操作的蒸发器要求其环形管板能承受０．１ＭＰａ的压力，在有限元计算中，列管对管板的支撑作用由８个同心圆筒来模拟，计算结果表明该管板在０、１ＭＰａ的压力作用下，板内应力未超过许用值。

| Abstract: | The deflection and the stress in an annular tubesheet of an evaporator were calculated by the finite element method with special consideration taken for the supporting effect of the tube bundle. The maximum stress occured in the tubesheet is smaller than the allowable value stipulated by the National Code of China for tubular heat exchangers. |
