| Abstract: | By interpolating and fitting the single-dimensional temperature field with single-dimensional linear interpolation method,we provide a simplified and feasible plan for the problem of blade vibration analysis using FEM under the temperature load.To verify the linear fitting plan by FEM,we applied several confirmation methods-checking the computation results and making error analyses on the partition interpolation of single-dimensional steady state temperature field,and obtained a finite element analysis comp... |
