【摘要】 本文介绍了φ1100×10000横式连续蒸煮管大开孔应力—应变测试情况,分析了大开孔接管附近应力分布状态及外表面最高应力点位置及应力水平,分析了法兰力矩对开孔高应力区应力的影响。测试结果将为横式连续蒸煮管大开孔补强设计规定的编制提供宝贵的实验依据。更多还原

【Abstract】 The stress-strain analysis of the large openings in a horizontal tubular continuous digester with dimension φ1100 × 10000 is measured. The pattern of the stress distribution near the large openings, the position of the highest stress on the surface and extent of the stress are analysed. The effect of the moment of the flange on the area of high stress near the openings is studied. The results of the test will be used as an important experimental basis on setting up the design criterion of the reinforcement for large openings in horizontal tubular continuous digesters.更多还原
