Preprocessing of 3-D Finite Element Models of Steam Turbine Blades

Abstract Making use of the idea of discretizing an integral structure by parts into elements and then assembling them to form the integral body,the paper presents the conception of a coordinate system of an integer domain,herewith solving the problem of joining the parts and handling the boundary conditions.Thus a finite element preprocessing procedure,suitable for three dimensional structures,is worked out. A finite element preprocessing program for steam turbine blades has been developped which has successfully been used for their 3-D finite element analysis.
