Abstract
The new optimization procedure of the tire block surface is proposed, in which FEM is combined with the optimality criteria. The objective function is the pressure uniformity on the block and the constraints are the contact area. We verified the effectiveness of this new procedure by the block samples. The block with the optimized surface has the uniform pressure distribution and the friction coefficient is increased ten percent compared with the block with the flat surface. Furthermore this procedure was applied to the tire block surface and was verified to be effective to improve handling, riding comfort and irregular wear.
