Abstract

The invention provides a tire air coupling ultrasonic NDT (Non-Destructive Testing) device and method. The method can be used for carrying out NDT on a tire in an air coupling way by utilizing low-frequency ultrasonic waves and comprises the following steps of: analyzing and judging in real time to obtain the damaged condition of the tire in the process of ultrasonic scanning on the tire; then marking the damaged part of the tire; and finally sending an analysis result to a control end and visually displaying the analysis result to the operator of the device in the form of a 3D (Three-Dimensional) view and a three-side map. In the testing method, the damaged condition of the tire is shown by using a simple and visual tire health position map without a fluid couplant, and finally the damaged condition of the tire is visually displayed in forms of damage marking, the 3D view and the three-side map so that the tire testing process becomes simple, visual and efficient, the tire testing cost is lowered, and the practicability for tire ultrasonic NDT is increased.

Description

technical field [0001] The invention relates to the field of non-destructive testing of rubber, in particular to the field of non-destructive testing of automobile tires. Background technique [0002] Non-destructive testing of tires is one of the important steps in tire retreading. Tire retreading refers to a process in which old tires are partially repaired, processed, and reapplied with tread rubber, and then vulcanized to restore their use value. It is an important link in the tire recycling industry chain. As our country proposes to establish a development strategy of "resource-saving, environment-friendly, and reliable quality", the recycling and reuse of waste tires has been listed as a key development industry, and the tire retreading industry has achieved greater development. In recent years, the production of retreaded tires in my country has been increasing year by year. The output of retreaded tires was 3.5 million in 2000, 4 million in 2001, 4.9 million in 200...
