Modeling of the Hydroplaning Phenomenon
Hydroplaning is a unique phenomenon in which the water on a wet runway or highway is not displaced from the nominal tire-ground contact area by a rolling tire or by a moving but nonrotating (full-skidding) tire at a rate fast enough to allow the tire to make contact with the ground surface over its complete nominal footprint area, as would the case of operation on a dry surface. When hydroplani...
متن کاملInvestigation of the Effect of Dimple Bionic Nonsmooth Surface on Tire Antihydroplaning
Inspired by the idea that bionic nonsmooth surfaces (BNSS) reduce fluid adhesion and resistance, the effect of dimple bionic nonsmooth structure arranged in tire circumferential grooves surface on antihydroplaning performance was investigated by using Computational Fluid Dynamics (CFD). The physical model of the object (model of dimple bionic nonsmooth surface distribution, hydroplaning model) ...
متن کاملA Tire Side Slip Model with Flexible Tire Carcass and the Identification of Tire Structural Parameters
i’ire behaviour plays a very important role in vehicle dynamic studies. Because of the complexity of tire structure, some tire models use so many assumptions they cannot represent tire behaviour well, while others are so complicated they are di@icult to use in engineering applications. This study presents an analytical tire side slip modeI with flexible tire carcass which is very helpful for un...
متن کاملEstimation of Tire-Road Friction by Tire Rotational Vibration Model
Tire-road friction is the most important piece of information used by active safety systems. However, most conventional friction estimation/ detection methods are accurate only within the non-linear region. In addition, such methods require numerous sensors, such as yaw rate sensors, acceleration sensors, and steering angle sensors. In this paper, a friction estimation method using a tire vibra...
متن کاملAugmented Lagrangian and penalty methods for the simulation of two-phase flows interacting with moving solids. Application to hydroplaning flows interacting with real tire tread patterns
The numerical simulation of the interaction between a free surface flow and a moving obstacle is considered for the analysis of hydroplaning flows. A new augmented Lagrangian method, coupled to fictitious domains and penalty methods, is proposed for the simulation of multiphase flows. The augmented Lagrangian parameter is estimated by an automatic analysis of the discretization matrix resulting...
