According to the one-dimensional linear piecewise interpolation method, the one-dimensional temperature field is fitted by piecewise interpolation, which provides a simplified and feasible scheme for the application of temperature load in the vibration problem of the blade under the action of the temperature field by the finite element method. The finite element method The linear fitting scheme is feasible and a variety of methods are used to validate and analyze the calculation results. The error analysis of one-dimensional steady-state temperature field is carried out. The finite element analysis of the blade vibration problem under steady-state temperature field is obtained Calculation method and temperature load application scheme.
