某型号非金属发泡承压件在使用中内压极限强度不变, 而外压极限强度偏低。为此通过调整承压件的结构, 研究高径比对非金属发泡承压件的内压极限强度和外压极限强度的影响。结果表明: 当保证内压极限强度不变的情况下, 高径比的增加不利于非金属发泡承压件外压承载能力的提高。

In use, the ability of internal endurance of a type nonmetallic frothy pressure part was not changed and the ability of external endurance of that was relatively low. By changing the structure of the part, the influence of ratio of height to diameter on the abilities of internal endurance and external endurance was researched. The results indicated that when the ability of internal endurance of the nonmetallic frothy pressure part was not changed and to enhance the ratio of height to diameter cannot enhance the ability of external endurance.
