Strength Analysis of High and Intermediate Pressure Casings of 300 MW Steam Turbine

The calculations of the strength,stiffness and steamtight are very importang when high pressure and intermediate pressure casing of 300 MW steam turbine are designed.Based on the elastic contact theory,a three dimensional finite element model of 300 MW steam turbine is developed to calculate the temperature field,stress and deformation.The result of the calculations are conform with the fact.It shows the numerical analysis can provide usable data for casing design and improve its reliability.
