Abstract
This paper presents the results of software (ANSYS software) improvements specific for modeling the physical process of SLM (Selective Laser Melting). Improvement goal was to create a set of mathematical models and user environment (a set of APDL programs) based on the ANSYS finite element analysis system solver, allowing to perform the technological procedure of physical SLM process numerical modeling to the required degree of precision with an estimate of the final distortion and residual stresses of gas turbine engine parts to optimize the manufacturing process.
Highlights
Additive Manufacturing enables manufacturing of parts by means of additive layer synthesis and getting complex topology parts
The objective of this work is to generate a set of mathematical models and user environment (APDL program set) based on ANSYS Finite Element Analysis System solver which would allow performing, with the required degree of accuracy, the technological operation of numeric prediction of manufacturing and residual stress fields formation and displacements in the process of Selective Laser Melting of gas turbine engine components blanks for further optimization of manufacturing process parameters
The problem of determining the evolution of the system stress-strain state in the conditions of building up by selective laser melting (SLM) may be divided in 2 successive problems: unsteady heat conduction and quasi-steady problem of deformable solids mechanics which uses temperature profiles found at the first stage as volumetric loads
Summary
Additive Manufacturing enables manufacturing of parts by means of additive layer synthesis and getting complex topology parts. From the time AM technologies came into use significant progress has been achieved in understanding the processes, structure and properties of the parts being made. The objective of this work is to generate a set of mathematical models and user environment (APDL program set) based on ANSYS Finite Element Analysis System solver which would allow performing, with the required degree of accuracy, the technological operation of numeric prediction of manufacturing and residual stress fields formation and displacements in the process of Selective Laser Melting of gas turbine engine components blanks for further optimization of manufacturing process parameters
