Tokyo--Bridgestone loves acronyms. The latest is CROSS, for Comprehensive Road Surroundings Simulation, which is a system to use powerful computers to simulate the deformation of soft ground as a tyre rolls over it.
Bridgestone claims CROSS, "incorporates a breakthrough in analyzing terramechanics, which is the behavior of soil under loads. Bridgestone uses a supercomputer to predict the movement and response of soil as it is compacted under a rolling tyre. That will streamline work in optimizing tread patterns on tyres for four-wheel-drive vehicles, earthmoving equipment, agricultural machinery, all-terrain vehicles, and other vehicles that operate on unpaved surfaces. "
The company said one of its engineers gave apaper at the September Tire Society meeting in the USA that underlies the technology
