X-RAY AND CT TYRE ANALYSIS

The group of non-destructive testing units, comprising shearography, computed tomography and X-ray analysis, form another department at Continental Tyres R&D.

Shearography is a laser-assisted, optical measurement technique for detecting irregularities in the tyre such as air bubbles. X-rays and CT scans are used to take an even deeper look into the material. Hanover-Stöcken is the only site within the Continental Group to boast the requisite facilities, complete with analytical laboratories. Continental has been using computed tomography since 1997. The process has been continually improved over the years, as a result of which the time required for a 2D scan has been cut from one hour to just three minutes.

The linear accelerator has sufficient power to “see” right through even thick-walled truck tyres without image artefacts, meaning that even the tiniest deviations in the tyre’s construction can be identified.

The linear accelerator has sufficient power to “see” right through even thick-walled truck tyres without image artefacts, meaning that even the tiniest deviations in the tyre’s construction can be identified. Another standout feature is the ability to simulate various operating conditions by replicating different loads and tyre pressures during the scan. This makes it possible to conduct series of comparative tests with different tyre specifications.

With such a large number of tyres presented for testing, the team is constantly being confronted with new challenges – and their work never fails to yield surprising results. The testers help the product developers better understand the ins and outs of the material combinations so they can optimise their simulation models. Support is also provided for other business areas through investigation of technical products such as hydromounts for Vibration Control.
