E0018 tire contact patch(tire sideslip angle part 2) - EulSeoggy Ko - 笑える動画、感動する動画、話題の動画をご紹介します。

The direction of tire velocity is different from that of wheel heading when it has a lateral force because of tire deformation due to sideslip angle. This sideslip angle part 2 video explains the sideslip angle together with lateral force, normal force, cornering force, Tire contact patch can divide into 2 seperate parts. One is sticking area in which all the tire elements are sticking to the corresponding road surface and the other is slipping area in which all the tire elements partly or entirely experience the slip on the road surface. There is no relative velocity between tire elements and road surface in the sticking area. On the other hand, there is relative velocity between tire elements and road surface in the slipping area. Slipping area gets broader as sideslip angle gets bigger. This means lateral shear stress in the following half of contact patch decreases. On the other hand, lateral shear stress in the leading half is increases. Therefore, moment arm for self aligning moment is reducing as sideslip angle gets bigger. cornering force is changed depending on sideslip angle, the size of normal force and size of inflation pressure. This video explain what kind of tendency occurs in cornering force when those three factors changes in their practical range.
