Instrumentation Model and Data Processing of Tire Dynamic Balance Using Multi-Sensors

The instrumentation of dynamic balance for automobile tire often uses multi-sensors and requires effective data processing techniques. In this paper, the mathematical instrumentation model is developed by considering the eccentric force and moment caused by unbalance mass. Furthermore, the data processing techniques based on the least squares are used to reduce the influence of measurement noise and improve the accuracy of unbalance instrumentation. It is shown that the proposed method can provide effective instrumentation for the tire dynamic balance.
