Foreword

Appendix A of this standard is an informative annex. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee aviation tires. This standard was drafted. Shuguang Rubber Industry Research and Design Institute. The main drafters. Zhang Ping, Sheng Baoxin. Aviation tires Digital Laser NDT method

1 Scope

This standard specifies the aviation tires laser digital NDT method principle, samples, testing equipment, testing conditions, the step of detecting The results of the analysis to determine the method and test report. This standard applies to digital laser aircraft tire NDT. Principle 2 This method utilizes a digital laser speckle technology dislocation by vacuum loading internal defects tire is deformed, with a specific wavelength of the laser source Irradiating vacuum load before and after the tire surface, resulting spot on the grating, and then use a digital camera (CCD) direct uptake spot before and after deformation Image, computer digital image distortion before and after derivative overlay operation, the operation result is converted into a digital image display. by Observation of phase diagrams and video images of the features inside the tire markings identifying the presence of delamination, bubbles and other defects.

3 Sample

After curing the specimen should be parked at ambient temperature for more than 12h, surface-quality inspection and clean the surface of the tire.

4 Testing Equipment

Tire digital laser speckle dislocation Nondestructive Testing (its sensitivity should be greater than or equal to 1mm). The instrument includes a host (the vacuum chamber, the Lower bead means), digital laser speckle displacement detection system (digital cameras, sports bodies), image analysis and processing system. Recording medium with a hard Disk, removable disk or printer output.

5 test conditions

5.1 clean laboratory requirements, relative humidity less than 70%, the test environment temperature controlled at 10 ℃ ~ 40 ℃. 5.2 submission of the tire should ensure that internal and external surfaces clean and dry. If two narrow bead spacing can be properly flared, lined bead dilator, standing Detection can be carried out after 30min. 5.3 Check the load degree of vacuum, according to technical requirements of the selected equipment factory.

6 detection step

6.1 to be detected aircraft tires are numbered in numerical order the registration number on the tire tread. 6.2 Opening detector power adjustment device so that it is in the initial state. 6.3 Setting parameters, including the degree of vacuum, number of detections and other sectors. 6.4 The tire load detector detects, through the display monitor the testing process, test results stored in the hard disk or removable disk, you can use The printer will print out. 6.5 After each test the tire automatically exit detector. 6.6 According to test results, do the inspection records.

7 Results of detection and determination method

7.1 determination of defects Carefully observe the display on the screen dislocation speckle pattern, if the picture is evenly distributed, is clear, then the inside of the tire without defects; if the image appears Snowflake-shaped geometry, butterfly-shaped stripes or white stripes, then the interior of the tire where the presence of delamination, bubbles and other defects. Tire defect-free ......
