Abstract
The dynamic fatigue analysis for spot welded joint based on natural frequency due to cycling loading is a study about the joining of material using resistance spot welding and been testing using TM16 Universal Vibration Apparatus which is vibration machine. The fatigue cause when the force where applied on the joined material. The problem is to know when the joined material were applied force, the strength on the weld nugget whether can withstand the force and the range of vibrations fatigue life. The vibrational will be result by its natural frequency. This is very important to know either it is safe to use this kind of joining on the material use. The focuses of this study is on using a different thickness and type of material. The aluminium and galvanized iron with thickness 0.5mm and 1mm each were applied in this experiment. The parameter of spot welding machine was set for each of the specimen. The result which is the natural frequency and amplitude reading obtained from the experiment were plotted for each specimen. The result shows that the aluminium joining has more amplitude peak than the galvanized iron joining. The result for aluminium joining for 1mm is 0.4mm peak amplitude and natural frequency is 20.75Hz, 21.92Hz, 22.65Hz, 55.65Hz, 70.38Hz and 80.79Hz. The galvanized iron result is 0.4mm peak amplitude and natural frequency is 180.55. This happen because the aluminium has a most vibrate condition. For joining dissimilar material thickness 1mm each shows the improvement on rate of vibration condition with 0.4mm peak amplitude and natural frequency is 75.65Hz. Its shows that the joining of galvanized iron are better and strong material than aluminium.
