Modal Analysis, Computational Fluid Dynamics and Harmonic Response Analysis of a 3D Printed X-ray Film Handler for Assistant Robotic System using Finite Element Method

Abstract

This paper presents a modal analysis, Computational Fluid Dynamics (CFD), and harmonic response analysis for a 3D printed retractable x-ray film holder designed for a novel assistant robotic system. The x-ray film handler is more prone to wind and other external load which made it critical. Hence, optimizing the design based on simulation result is valuable. Based on harmonic response analysis, in a maximum wind load condition, it shows that there are max deformation and stress of 22mm and 0.013Mpa respectively with a resonant frequency to be near 7Hz when subjected repeatedly with the same load. In addition, compare with total length and dimension ratio of the part, deformation is still acceptable. Moreover, reinforcing the design through additional material on the frame is recommended since it is highly affected when excited with different vibration from the six-mode shape.
