Studi Eksperimental Pengaruh Variasi Beban terhadap Perilaku Keseimbangan Roda Mobil Pada Proses Balancing

Abstract

Tires are the medium that covers the rim of a wheel and are also components that are in direct contact with the track. One of the causes of vibrations in rotating wheels is due to an imbalance that occurs in the car wheels. The aim of this research is to analyze the effect of load variations on changes in wheel balance. This research was carried out using an experimental method, namely carrying out tests directly and recording the research results. The conclusions drawn from this research are: 1. The highest vibration acceleration for a load (200kg) is on the x-axis at 2.75 m/s2, the y-axis at 8.23 m/s2 and the z-axis at 1.47 m/s2, at load (400kg) the x axis is 3.85 m/s2, y axis is 8.7 m/s2, and z axis is 2.15 m/s2, at load (600kg) it is at the x axis 5.31 m/s2, the y-axis is 9.65 m/s2, and the z-axis is 3.26 m/s2. 2. By adding a balancing mass weighing 10 grams to the inner rim, the wheel balancing performance value obtained is 76% on the x-axis, 56% on the y-axis, and 53.8% on the z-axis. 3. The cause of imbalance in the wheels is that it can be influenced by gravity, friction and torque on the wheels, so the heavier the load given, the higher the vibrations on the horizontal and vertical axes, the impact of which can cause discomfort when driving.
