Bridgestone simulates ground deformation under tyres

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,…
