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:

[0063] ...

Abstract

The present invention is the measurement method of unbalance amount of tyre in dynamic balancing machine. During the measurement of static and dynamic unbalance amount of tyre with sensors, the linear mold of the corresponding relation between the unbalance amount in the calibrating plane and the sensor signals is established, so as to measuring static and dynamic unbalance amount of tyre accurately.

Description

technical field [0001] The invention relates to a method for measuring tire dynamic balance unbalance. Background technique [0002] At present, the number of domestic units and households buying cars has increased significantly, which puts forward higher requirements for the quality standards of the service life of car tires. [0003] Automobile tire is a circular rotatable body with cylindrical section, which is made of multi-layer rubber prefabricated materials with steel cords and composite rubber prefabricated materials through lamination, molding, vulcanization and setting. For tires with the above structure, the constituent materials inevitably have problems such as uneven distribution or misalignment between the center of mass and the geometric center of the tire (so-called mass eccentricity), which is often referred to as tire unbalance. According to relevant mechanical principles, tires with a certain degree of mass eccentricity will inevitably produce alternating...
