Using a computer simulation, it is possible to reduce the number of solution options for new challenges before the wheel goes into serial production. However, the ultimate conclusions are generated during the test procedure. The test criteria checked by BBS simulate the toughest road conditions to comprehensively cover both standard and specialist tests. Yet these test criteria are still not enough for us, and some of our own standards outstrip the legal requirements in terms of long-term usage and rigidity tenfold.
Overview of BBS test scenarios:
Cyclic bend check
This test simulates the side pressure that is applied to the wheel when cornering. A tension ring is rigidly mounted to the inner rim shoulder and is subjected to a cyclic bending moment.
Two axial wheel test
With this test BBS is able to simulate both the side and normal pressure applied from the vehicle to the wheel. For example, using the Nürburgring or Hockenheim test, BBS can bring Formula One circuits 1:1 into its test facility so that it can put its wheel types through its paces under the hardest of conditions.
Impact test
This test simulates the impact of hitting the curb from the side. A falling weight is dropped several times onto the outer rim shoulder of a tyre-covered wheel. It is important that there is no sudden loss of air from the tyre.
