Forced Frequency Response Analysis of a Gudgeon Pin

Abstract

In this study, forced frequency response analysis was applied on the gudgeon pin. Ansys Mechanical 19.2 program was used to analyze the vibration on the gudgeon pin. Once completed in the finite element analysis, a note from the modal results, the model's natural frequencies range from 38721 to 79346 Hertz for the first 12 modes. According to the modal analysis results, the gudgeon pin will not be subjected to resonance during working. Therefore, a frequency scan including modal analysis is required to detect resonant frequencies that may coincide with the natural frequencies of the first 12 modes obtained in modal analysis. Consequently, harmonic analysis has been solved using the mode superposition method with 50 intervals with 1000 Hz steps in the range of 30000-80000 Hz. To dampen the resonant frequencies, harmonic analyzes were repeated using six different constant damping ratios, and the results were compared.
