重叠式浮头热交换器地脚螺栓计算
|
摘要
在直径较大的重叠式浮头热交换器的设计计算过程中,存在由地震引起的地脚螺栓拉应力过大而无法通过校核的问题,需要对增大地脚螺栓直径及改变材料等方式进行适当的调整。介绍了地震烈度的分类情况和鞍式支座校核计算方案以及用PV Desktop计算软件对列举的实例进行分析-调整-再分析的计算校核过程。
In the design and calculate process of large diameter overlap-floating heat exchanger,generally,the anchor bolts stress could not approved because of its too much seismic forces.So the saddle support needs to adjust properly,while,increase the diameter of anchor bolt or changed materials and so on,which is the most convenient selection.The calculation process of adjustment and the scheme of saddle support’s checking calculation were introduced.And by using of the software PV Desktop flexibly to do the analysis-adjustment-reanalysis calculation checking process to example,the reasonable solution is given.
