Conical Head

Study on feasibility of conical head with half top angle>60°;

半顶角大于60°锥形封头的可行性研究

In this paper, two problems-the design of conical heads subjected to external pressure and stress intensity existing around opening are analyzed and discussed.

本文对外压锥形封头设计以及开孔接管处的应力强度等两个问题进行分析。

In this paper,the authors carried out stress analysis for knuckle (transitional section) of toriconical heads (conical heads with transitional section),proposed another rule design method based on membrane theory,which is contrasted with the rule design method in operation,for the knuckle of toriconical heads.

对折边锥形封头的过渡段部分进行应力分析，提出以无矩理论为基础的常规设计方法，并与现行常规设计方法（国家标准ＧＢ１５０—８９《钢制压力容器》所规定的方法）进行比较，同时研究了计算厚度公式。

Calculation method on stress intensification factor of hem pyramidal head that mentioned in GB 150—1998《Steel Pressure Vessels》was derived and analyzed.

推导分析了GB 150-1998《钢制压力容器》中折边锥形封头应力增强系数K的确定方法。
