Abstract: According to hydrodynamic lubrication theory,tyre viscous hydroplaning was simulated as the squeezing film problem of tread element.The mathematical model for the squeezing film problem of tyre tread element was presented and solved numerically.Taking parallelogram shaped tread element as an example,the effect of tread element design on tyre viscous hydroplaning performance was analyzed.The results obtained provide a theoretical basis for anti slip design of the tread element.
