摘要
内压作用下,椭圆形或碟形封头上开孔补强范围的位置不同,开孔补强计算时所用的封头的计算厚度也不同。根据不同计算厚度得到的开孔所需的补强面积和封头所能提供的补强面积不同,因而整个开孔补强计算的结果也会不同。
When we calculate the opening under internal pressure,the different location of reinforcement chooses the different calculation thickness of head.According to the different calculation thickness,the required area after opening and the available area in head are different,and this leads to a distinct result of the calculation of opening.
