近日在东京举行的第26届计算流体动力学研讨会上,日本横滨橡胶公司宣布它已开发出可降低空气阻力的轮胎设计技术。横滨橡胶公司表示,明年2月5-7日在德国科隆举行的轮胎技术博览会上,它将展出这一新技术。该技术是通过改善车辆行驶时轮胎周围的空气流动,使得滚动阻力进一步降低,从而有利于环境保护。据介绍,当车辆移动时,轮窝(轮辋中部凹进部分)内的空气流会发生湍动,其中一些空气从车辆侧面流出,导致空气阻力出现恶化。横滨 At the 26th CFD Symposium held in Tokyo recently, Yokohama Rubber Japan announced that it has developed a tire design technology that reduces air resistance. Yokohama Rubber said it will exhibit the new technology at the Tire Technology Expo February 5-7 next year in Cologne, Germany. The technology is beneficial to the environment by improving the air flow around the tire when the vehicle is running, so that the rolling resistance is further reduced. It is reported that when the vehicle moves, turbulence occurs in the flow of air in the wheel well (the central recessed portion of the rim), and some of the air flows out from the side of the vehicle, resulting in deteriorated air resistance.
