Abstract

The embodiment of the invention discloses a method for measuring the amount of unbalance of tire dynamic balance, which comprises the following steps of: detecting an induction electrical signal of a main shaft connected with a tire in real time in a rotating process; if the rotating speed of the main shaft reaches a preset rotating speed threshold value and an identifier on the main shaft reaches a given position, sampling the induction electrical signal according to preset sampling information to obtain discrete data; calculating the amplitude and phase of the induction electrical signal according to the discrete data; calculating the magnitude and phase of an induced force corresponding to the induction electrical signal according to a linear model of corresponding relationships between the induced forces and the induction electrical signals; and calculating the magnitude and phase of the amount of unbalance of the tire on a corresponding corrected surface according to the magnitude and phase of the induced force and a balance principle. The embodiment of the invention also discloses a tire balancer. By the method of the tire balancer, the high-accuracy magnitude and phase of the amount of unbalance of the dynamic balance can be simply and conveniently measured and calculated.

Description

technical field [0001] The invention relates to the field of tire dynamic balance measurement, in particular to a tire dynamic balance unbalance measurement method and a tire balance machine. Background technique [0002] With the development of China's automobile industry, the demand for tire balancing machines is increasing, but the research and development and production of tire balancing machines in China are relatively backward. [0003] Unbalance is caused by the failure of inertial force or centrifugal inertial force to be eliminated. Unbalance is a vector. During the tire manufacturing process, the center of gravity of the tire does not coincide with the center of the rotation axis, and when it rotates around the axle, it generates inertial forces of different sizes in various directions. Tire imbalance is divided into two types: static imbalance and even imbalance. Tires with static imbalance will generate alternating radial force when they rotate at high speed, ...
