Abstract

The invention discloses a meridian aircraft tire geometric parametric modeling method, relates to the technical field of aircraft tire design, and solves the problem that existing tire geometric drawing is complex and time-consuming. The method comprises the following steps: according to the maximum diameter of the tire, the maximum width of the section of the tire, the diameter of a rim, the thickness of an inner liner, the thickness of a sidewall, the taper of a tire bead, the ratio of the width of a hub to the width of the section of the tire, the thickness of a tread, the transverse thickness of a bead heel, the longitudinal thickness of the bead heel, the thickness of a reinforcing layer, the diameter of a bead ring, the thickness of a carcass ply and the thickness of a belted layer; and establishing a three-dimensional model of the meridian aircraft tire according to the transverse distance between the apex and the center of the bead ring and the longitudinal distance between the apex and the center of the bead ring. According to the method, the geometric model of the meridian aircraft tire can be quickly and accurately established through 16 geometric information parameters, so that the research and development period of the meridian aircraft tire is shortened, and the capability of independent design of the meridian aircraft tire is promoted to be improved.

Description

technical field [0001] The invention relates to the field of aviation tire design, in particular to a geometric parameterized modeling method of radial aviation tires. Background technique [0002] Aviation tires are known as the "jewel in the crown" of the tire industry. Foreign tires can fly 250 sorties, while domestic tires can only fly 50 sorties. And domestic tires only account for 5% of the domestic market. Therefore, it is necessary to break through the technical barriers of foreign aviation tires as soon as possible and improve the ability of independent design. The emergence of radial aviation tires not only opens up a new development direction, but will also be a milestone in the development of aircraft tire technology. Compared with bias tires, radial tires have the advantages of low heat generation, long service life, low tire weight, high tire retreading rate and low running cost. However, due to the small radial rigidity of radial aviation tires and the lar...
