外压锥壳上加强圈设计方法分析

Analysis of Design Methods for Reinforcing Ring on Conical Shell Subjected to External Pressure

通过分析外压锥壳大端或小端与圆筒连接处的加强设计原理,给出了外压锥壳上设置加强圈时锥壳段稳定性计算方法,并指出在进行加强圈惯性矩计算时,可以将加强圈和加强圈中心线至相邻加强圈中心线距离之半范围内的锥壳处理成当量圆筒,再根据外压圆筒加强圈设计方法进行计算。

By analyzing design methods to strengthen the connection between the large end of conical shell or the small end of conical shell and cylinder, the methods for stability calculation of conical section was provided when reinforcing rings were set on conical shell subjected to external pressure, and pointed out that the reinforcing ring and the conical shell within the scope of half distance between the adjacent reinforcing rings could be treated as the equivalent cylinder when calculating the moment of inertia of reinforcing rings, then the design methods to calculate reinforcing rings of cylinder subjected to external pressure can be used for reinforcing rings of the conical shell subjected to external pressure.
