压力容器特殊开孔结构的补强计算

Reinforcement Calculation for Special Opening Structure of Pressure Vessels

某些制冷装置用压力容器因结构设计的要求,需要设计成一种特殊的开孔结构,通过对此结构进行受力分析,发现可以采用等面积补强方法对本开孔结构进行补强计算,且计算结果偏于安全。基于等面积补强计算方法,给出了开孔补强计算公式,并提出此开孔结构在设计、制造方面需注意的要点。

Some pressure vessels in refrigeration units ask for a special open-hole structure due to the requirements of structural design.The force analysis of the structure found that,the method of equal area reinforcement can be adopted for the reinforcement calculation of the open-hole structure and the calculation results are biased to safety.Based on the calculation method of equal area reinforcement,the calculation formula of opening reinforcement was presented and the key points needing attention in both design and manufacture of the opening structure were put forward.
