四鞍座设备的强度校核

Four Saddle Equipment Strength Test

将卧式容器的多鞍座问题转化为多个双鞍座卧式容器来计算。利用三弯矩方程,分别计算各鞍座处的弯矩、支承力和极值弯矩,找出最大弯矩和鞍座反力。按NB/T 47042—2014《卧式容器》中的公式和方法进行应力计算及校核,得到强度校核结果。

By transferring the calculation model of horizontal multi-saddle vessel into muhiple double-saddle vessel, the bending moment, bearing force and maximum bending moment of each saddle point were calculated separately through three moment equation. As a result, the maximum moment and support pressure could be obtained. According to the formulas and methods of horizontal vessel NB/T 47042-2014, the stress was calculated and checked, then the strength of the test results were obtained.
