ERJ - Simulation technology improves Yokohama tire design

Burlington, Massachusetts – Software company Exa Corp. has helped Yokohama Rubber Co. to develop advanced aerodynamic tires through simulation-based design, the Japanese tire-maker announced on 26 May.
 
The products, designed with Exa PowerFLOW software, have fins on the tire sidewall to streamline airflow around the tires when in motion and contribute to the overall efficiency and safety of the vehicle.
 
Explaining the virtual development, Yokohama said it was still difficult to precisely analyse and optimise the design of tires using conventional development procedures such as wind-tunnel testing.
