摘要
对某电厂 5 0MW汽轮机不同运行条件下高压汽缸的温度场、热应力场以及由内压引起的应力进行了三维有限元分析。结果表明 :计算的最大应力部位与汽缸的开裂部位完全吻合 。
A three dimentional finite element analysis of the temperature field and the thermal stress field regarding a 50MW steam turbine's high pressure cylinder in a powr plant under different operation conditions has been carried out. The results show, the position of calculated max. stress tallies completely with that of the cracked cylinder, providing important technical basis for evaluating the steam cylinder's safety and calculating the said cylinder's residual service-life.
