Abstract Methods are considered for solving design and technological problems at the design stage of the radial tire specification. On the basis of the theory of gridshells, a scheme is constructed for calculating the distribution of materials in the radial section of an uncured and vulcanized radial tire. For a flat method of assembling the radial tire, algorithms for calculating profiled parts are proposed. Algorithms are considered for finding the geometry of the shaping surfaces of the tread and sidewall parts. The boundary-value problem of finding the profile of the molded uncured tire at the second stage of assembly has been solved. A method is proposed for determining the parameters of industrial equipment for tire assembly. The experiments carried out to test the accepted hypotheses of the theory of elasticity are described.
Keywords car tire, design and check calculation, equilibrium configuration, flat assembly method, rubbercord system of the breaker and frame, profiled parts, part pressing by thickness, part pressing by width, assembly drum of the first and second stages, electronic prototype of the tire, stress-strain state of the tire, all-steel tire, design and technological map
