摘要
工业驱动用汽轮机随着功率的增加,结构尺寸也越来越大,动子和静子在自重作用下会产生不可忽略的挠曲,进而影响动静间隙的大小。根据某大功率驱动用汽轮机的实际结构,采用有限元方法计算了静态下汽缸和转子的挠度,从而给出汽轮机本体结构对动静间隙设计的影响。
With the increase of rated power of industrial driving steam turbine, the structure becomes larger and larger, and the deformation of active cell and stator cannot be ignored The deformation of the casing and the rotor of a specified high-power steam turbine is calculated by finite element method. The deformation analysis will be helpful to the design of radial clearance between casing and rotor.
