摘要
研究了椭圆形截面容器在升压过程中的趋圆变形对弯曲应力的影响,建立了弯曲应力通用计算公式和简化计算公式,导出了由圆度引起的圆筒形容器最大弯曲应力计算公式,给出了椭圆形截面容器壁厚的计算方法。
The impact of the shape-change trend towards round on bending stress during the process of pressure increase was researched, a common formula and a simplified one for bending stress calculation were established, the formula of maximum bending stress caused by round degree of cylindrical vessels was deduced, the calculation method for wall thickness of pressure vessels of elliptical cross section was introduced.
