Tire/Wheel Assembly Unbalance와 Match Mounting 에 관한 연구 = A Study of Tire/Wheel Assembly unbalancc and their Match Mounting

다국어 초록 (Multilingual Abstract)

The uniformity of tire/wheel assembly, such as radial force variation and balance, causes the vehicle vibration which is called shake or shimmy.Especially the assembly uniformity depends on the tire/wheel match mounting method. Therefore, in order to reduce the vehicle vibration, a various method can be considered. Currently the matching method based on tire radial force variation is popularly used in car makers because dynamic balance can be corrected with balance weights.But nowadays users are concerned in looking also, so car makers require low unbalance of tire/wheel assembly.<br/>
In this study a new method was proposed to improve the tire/wheel assembly's unbalance through theoretical & experimental approach. First of all,characteristics of tire and wheel which can affect assembly unbalance were studied. And new quantities related to wheel run out was defined. Based on simpe theoretical formulation, simulation study by Monte Carlo'smethod was performed in order to reduce the assembly unbalance and the results were comparcd to that or experiments.<br/>
The results may imply some problem such as shake which is related to the mismatching of force variation. But, due to the improvement of quality control for tire and wheel property, the suggested new method can attribute good quality to vehicle.<br/>
