Fatigue failure behaviour of horn mounting bracket using finite element analysis

Abstract The aim of this present work is to find natural frequency for both existing and proposed horn mounting bracket designs to avoid the possibility of resonance. Next is to find out the dynamic behavior of existing bracket assembly from 5 to 17.3 Hz at the peak to peak distance of 10 mm by means of harmonic response analysis and then to find out the fatigue life using Goodman curve by vibrating the bracket assembly at first resonance frequency at 1.5 G acceleration. Finite element analysis (FEA) is carried to analysis the horn mounting bracket using ANSYS workbench software.
