Tire performance prediction method, field simulation method, tire design method, recording medium and tire performance prediction program

摘要

PPROBLEM TO BE SOLVED: To facilitate the estimation of a tire performance which is actually used through a field such as soil. PSOLUTION: After performing an actual field measurement (a step 300), a relationship of the void ratio, the pressure, and the shear strength of a field is function-approximated by a polynomial (302), and the field is modeled from the function expression, and a tire model is manifolded (304). The shear strength to a stress for each element of the field model is calculated by the function expression (306), and a shear stress distribution which acts on the tire model is calculated (308). A traction is calculated by integrating the shear stress (310), and is output as an estimated value (312). PCOPYRIGHT: (C)2006,JPO&NCIPI
