【摘要】 本文阐述了聚四氟乙烯膨胀节在室温和加温下爆破和疲劳试验过程,提出了可供工程分析和应用的爆破和疲劳计算公式,揭示了此种膨胀节承压和位移的能力,并对内压应力、刚度和失稳等问题提出了一些看法。更多还原

【Abstract】 Polyflon bellows blast and fatigue experimental progress with room temperature and applied temperature have been investigated in this paper. The blast and fatigue calculating formula, which can be used and analysed in engineering projects, have been put forward. Abilities of this kind of bellows pressure and movement endurance have been revealed and views on the bellows behavior,such as interior pressure stress,spring rate, instability ete have been stated.更多还原
