摘要

PPROBLEM TO BE SOLVED: To shorten the time required for air leakproof performance test of a pneumatic tire. PSOLUTION: The air leakproof performance simulation testing method for pneumatic tire includes forming a finite element model which divides and expresses a pneumatic tire by two or more elements; calculating an air amount which transmits each element per time, based on an air transmission factor which indicates air permeability to each element, when air transmits each element of the finite element model extracting an air transmission amount AFLi per unit time which transmits each of two or more elements ELo, on the outer surface of the finite element model of the pneumatic tire among an information group of air amount per time which transmits each element; and computing an air transmission amount AFL per unit time which leaks from the outer surface, by summing the air transmission amount AFLi per unit time for all the elements ELo on the outer surface.
