Embodiment 1
[0060] Embodiment 1, combining figure 1 The structure of the dynamic balance testing machine shown, the measurement method of the present invention, after determining and installing the dynamic balance testing machine in place, select any tire to be tested with eccentric mass m, first establish the calibration coefficient k and the tire to be tested The linear mathematical expression between the unbalanced mass m and the measured unbalanced force couple N on the correction surface, the derivation process of the linear model is:
[0061] first step, such as figure 1 As shown, according to the principle of moment balance, the moments of the upper and lower correction surfaces are calculated respectively, and the centrifugal force generated by the upper and lower correction surfaces of the tested tire is calculated.
[0062] That is, the moment of the upper correction surface should be calculated, and the result should be 0, that is, ΣMs=0. Solutions have to:
