胎面花纹深度及车速影响滑水现象分析

Analysis of the Influence of Vehicle Speed and Tire Profile Depth on Tire Aquaplaning

基于轮胎在路面上的印迹形状,分析了滑水现象中锲形水层的成因,介绍了德国交通安全委员会针对各种轮胎建议的最小胎面花纹深度,并指出:当路面上有积水时,无论是旧轮胎还是新轮胎,车速都不应超过100km/h.

Shortage of the residual depth of tire profile can result in tire aquaplaning, which makes the contact between tire and road insufficient due to water layer. This can cause traffic accident during braking or steering. In terms of the tire impression figures on road, the forming mechanism of the tire aquaplaning is analyzed. The minimum of the residual depth of tire profile for different kinds of tires proposed by Germany traffic safety council (DVR) is introduced. It is emphasized that the vehicle speed should be less than 100km/h, when there is water layer on road.
