Abstract
Car shake is one of many kinds of vehicle vibration that causes customer dissatisfaction. Uniformity of tire and wheel assembly affects the vehicle vibration including car shake. In this study, the authors developed the estimation method to calculate the radial force vibration of tire and wheel assembly. The parameters used in this method are the radial force variation of tire, the radial runout of wheel, and so on. This estimation method is based on the complex functions and the Monte Carlo calculations. The complex functions are used to study the assembly condition of a tire and a wheel. The Monte Carlo calculations are applied to calculate the parameters from their statistical data such as averages and standard deviations. The estimated results are in good agreement with the experimental results. The authors concluded that this method is an effective tool to reduce car shake.
