【摘要】 首先分析了超压缸的应力分布特点,然后由第四强度理论推导出了超高压缸危险位置处(缸筒内壁)的当量应力的计算公式,并进一步建立了缸筒内压与缸筒径比及持久极限的量化关系。最后根据这些关系得到一些结论,这些结论对于如何有效设计使用缸筒具有一定的指导意义。更多还原

【Abstract】 The characteristics of stress distribution in super high pressure cylinder are analyzed at first. Then the formula of calculating equivalent stress at the dangerous position (inside wall) in super high pressure cylinder is educed according to the fourth strength theorem and the quantitative relationship in the cylinder’s inside pressure and diametrical ratio and the fatigue limit further is founded. Finally, some conclusions are gained from these relationships. These conclusions have a definite directive significance for how to design and use cylinder effectively.更多还原
