Özet
Bu çalismada, piston pimi üzerinde zorlanmis frekans yanit analizi uygulanmistir. Piston pimindeki titresimi analiz etmek için Ansys Mechanical 19.2 programi kullanilmistir. Modal analiz sonuçlarina dayali olan sonlu eleman analizi tamamlandiginda, modelin dogal frekanslari ilk 12 mod için 38721 ile 79346 Hertz arasinda degismektedir. Modal analiz sonuçlarina göre, piston pimi çalisma sirasinda rezonansa maruz kalmayacaktir. Bu nedenle, modal analizde elde edilen ilk 12 modun dogal frekanslariyla çakisabilecek rezonans frekanslarini tespit etmek için modal analizi içeren bir frekans taramasi gereklidir. Sonuç olarak, 30000-80000 Hz araliginda 1000 Hz'lik adimlarla 50 aralikli mod süperpozisyon yöntemi kullanilarak harmonik analizi çözdürülmüstür. Rezonans frekanslarini azaltmak için alti farkli sabit sönüm orani kullanilarak harmonik analizler tekrarlanmis ve sonuçlar karsilastirilmistir.
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.
