【Abstract】 The transient temperature and stress field during starting of a turbine first stage disc’s 3-dimensional model has been calculated by using the general finite element calculation program ANSYS.The non-linear behavior of the material,the inertia forces and temperature field’s boundary conditions have all been taken into account in the calculation.The special features of the temperature and the stress fields are being analyzed,accompanied by recommendations for design improvements.The calculation results may serve as a reference for fatigue life predictions of turbine discs.Figs 6 and refs 3.更多还原
