Studi Eksperimental Pengaruh Variasi Tekanan Udara pada Ban terhadap Perilaku Keseimbangan Ban Mobil pada Proses Balancing

Abstract

This research will aim to analyze the effect of variations in air pressure on changes in wheel balance, analyze the balance performance values of the wheels after balancing and identify the causes of imbalances that result in vibrations. The research was carried out to obtain results in the form of large changes in imbalance that occur after the balancing process with different load variations, as well as to find out the causes that really influence changes in balance so that we can find prevention or minimize damage to the wheels. The results of this research are (1) The results of the experimental study have been able to identify the behavior of changes in mass balance with variations in car wheel pressure. By measuring the vibrations on the wheels before balancing, it was found that the lower the air pressure, the greater the vibrations. (2) By adding a balancing mass weighing 10 grams to the inner rim, the wheel balancing performance value obtained at a pressure of 35 Psi was 76%. at a pressure of 30 Psi it was 56% and at a pressure of 25 Psi it was 53.8%. (3) Tires with a smaller pressure have a smaller percentage reduction in vibration during the balancing process compared to tires with a larger pressure and vice versa.
