摘要
依据GB/T 25198-2010中的相关内容推导出封头名义厚度与封头最小成形厚度之间的关系,并用这个关系对名义厚度进行验算,同时考虑到材料的厚度与许用应力之间的关系,最终确定封头的名义厚度。
According to GB/T 25198-2010 for the head, the relationship between head＇ s nominal and minimum thickness after forming was derived and then the nominal thickness was determined after having the material＇ s thickness and allowable stress considered. The results show that the head＇ s thickness obtained with this method can be efficient and safe.
