Abstract Scope |
The goal of this paper is to evaluate the affects of build support material on the ability to find internal defects in AM parts dynamically. The different resonant frequencies of parts are determined by the stiffness and mass involved in the mode shape at each resonant frequency. Voids or defects in AM parts will change the stiffness and mass therefore shift the resonant frequencies. The mass and stiffness of the entire system including the build support material will determine these resonant frequencies. This paper will investigate the use of FEA dynamic simulation to determine how different build support structures will affect the ability to find the resonant frequency shifts of AM parts due to voids and defects.This work was funded by the Department of Energy’s Kansas City National Security Campus which is operated and managed by Honeywell Federal Manufacturing Technologies, LLC under contract number DE-NA0002839. |
