Intact® SHEAROGRAPHY TIRE INSPECTION

The shearography tire test systems from Steinbichler Optotechnik have been developed for the non-destructive testing of new tires in R&D and quality control, as well as for the inspection of tire carcasses in the retreading industry. The technical basis of the systems is the phase shearography system. During the test cycle, a pressure difference (vacuum, e.g., 50 mbar) is generated in the vacuum chamber, thereby inducing deformations which are caused by the expansion of air pockets occuring in faulty areas in a tire carcass. With the phase shearography technique - a holographic measurement...

3 By phase shearography the interferogram is directly recorded by a CCD-videocamera. The phase image of the original state of the tire at normal pressure is stored in the image memory of the computer. The phase images of the deformed states of the tire at decreased pressure are subtracted from the stored phase image in real-time (video frequency). Fault-typical deformations are displayed as phase difference and interference fringes on the system monitor. The results can be stored for documentation on: hard disk of computer, CD, DVD, laserprinter, customer network. PHASE SHEAROGRAPHY:...

Typically, the inner side of the tire tread is measured in 8 sectors. Before starting the test cycle, the tire is horizontally loaded into the vacuum chamber. The measuring head rotates inside the tire. The high flexibility of the tire testers allows testing of tires with a wide range of diameters and sizes without any system changes. With a tilting axis on the measuring head the inspection of the bead and sidewall of the tire is also possible. Owing to the fact that all typical faults in a tire can be detected with the Intact systems, high safety standards are achieved. Especially for the...

Intact® SOFTWARE A significant feature of the tire test systems from Steinbichler Optotechnik is the easy operation based on a user-friendly Windows software. The Intact system series is especially designed for performing test cycles without needing continuous input from the operator regarding test parameters and decisions in selecting an appropriate test program. Thus, the user can concentrate on the tires to be tested, only ensuring the tire supply and optionally deciding whether the sidewall area should be also inspected. In a matter of minutes, the systems deliver clear results....

7 The Intact software represents the GUI (Graphical User Interface) developed by Steinbichler Optotechnik which provides a unique and user-friendly desktop based on the well-known Windows tools. The software has been developed in close cooperation with our customers providing their valued input directly from the shop floor. For an example, the integrated diagnosis functionality reduces service work to a minimum. Using simple and self-explaining buttons and a well-designed, clear windows structure, we achieved a high level of system integration which has set standards in shearography tire...

Due to the used computer technology, the systems can be perfectly integrated into existing network and database environments. A high number of the systems already delivered are equipped with a barcode reader and connected with customer-specific conveyor systems. Thus, the system can be operated in a fully automatic mode with subsequent result classification. Optionally available fault detection algorithms further enhance the automation in the interpretation of fault areas by offering automatic recognition of fault-free or definitely faulty tires. This means that only critical decisions have...

9 FUNCTION OVERVIEW Intact® SOFTWARE FUNCTIONS Fully automatic tire loading • Automatic tire size detection • Automatic parameter selection for the loaded tire without the need of operator input • Measuring technology applicable even for new tires with extremely shiny surface • Automatic hardware system test with every program start • Program for manual parameter settings (with collision protection); e.g., for tire development • Tread, bead-to-bead, bead only and continuous run mode for every test type • Hot-key or button functionality on GUI • Freely selectable supervisor, operator and...

10 Intact® 1200-1 / Intact® 1200-2: PASSENGER CAR / (LIGHT)TRUCK TIRES The shearography tire test system Intact 1200-2 for passenger car, light truck and truck tires has been especially developed for tire manufacturers and retreaders operating with a high daily capacity. Owing to its high efficiency, the Intact 1200 can be used for a 100 % control. Due to the short cycle time of only 1 minute which includes the loading/unloading as well as the complete test of the tread and shoulder area of a tire, the system is suitable for testing both the incoming carcasses and the retreaded tires as...
