Shape design process of engineering products and pneumatic tire designed using the present design process.U.S. patent: 6,868,716 Issued: March 22, 2005 Inventors: Toshihiko Okano and Masataka Koishi Assigned: Yokohama Rubber Key statement: This process realizes a smooth optimal tire contour contour or contour line, line on a topographic map connecting points of equal elevation above or below mean sea level. It is thus a kind of isopleth, or line of equal quantity. that reduces rolling resistance Rolling resistance, sometimes called rolling friction or rolling drag, is the resistance that occurs when an object such as a ball or tire rolls. It is caused by the deformation of the wheel or tire or the deformation of the ground. coefficient coefficient /co·ef·fi·cient/ (ko?ah-fish´int) 1. an expression of the change or effect produced by variation in certain factors, or of the ratio between two different quantities. 2. while increasing the lateral spring constant of the tire for good drivability. |
