摘要：针对蒸汽发生器管板材料和传热管材料进行常温力学性能测试,获得材料的真应力-真应变曲线。在此基础上,对蒸汽发生器管板开展液压胀管的数值模拟研究,研究胀接压力和胀接长度对残余接触压力和过渡区残余应力的影响,得出以下结论:残余接触压力随胀接压力的增大而增大,与胀接长度基本无关,过渡区段传热管内壁最可能发生应力腐蚀。
For the tube sheet material and the tube material of the steam generator, according to the room temperature mechanical performance test,, the true stress-strain curve was obtained. On this basis, the numerical simulation of the hydraulically expanded tube-to-tube sheet joints in the steam generator is conducted, and the effect of the expansion pressure and length on the residual contact pressure and residual stress were studied in this paper. The results show that, the residual contact pressure increases with the increasing oftJhe expansion pressure and has nothing to do with the expansion length. Stress corrosion is likely to occur on the inner wall of the tube transition zone.
