Embodiment Construction

[0023] The invention provides a simulation method for the radial tire building process. figure 1 The flow chart is implemented for the simulation of the radial tire building process according to the present invention. In this embodiment, the first step S1 is to arrange at least one finite element model E (three subsystems, namely the sidewall part, the crown part and the apex part) on the meridian surface of the corresponding forming hub by using the finite element method, so as to Simulate the subsystem model and the corresponding molding equipment model.

[0024] For the finite element model E, the axisymmetric quadrilateral and triangular elements are preferred to simplify the rubber part, the axisymmetric surface elements are preferably used to embed REBAR elements to simplify the cord part, and the axisymmetric rigid elements are preferentially used to simplify the corresponding molded hub part. According to the finite element theory, the physical properties of the rubbe...

Abstract

The invention relates to a method for simulating a radial tire forming process. The method comprises the following steps: S1, simulating a tire construction component model for numerical computation by using a finite element with at least one elastic element; S3, simulating a sub-system forming process; S7, simulating the forming assembly process of the tire on a forming hub; and S8, obtaining at least one physical parameter related to the tire forming. The invention has the advantages of wide application range, high precision, large information amount and the like, and can overcome the defects of the traditional method, effectively predict the overall performance of the tire before and after forming and conduct the construction design (mouth shape design and working condition design) so as to minimize error of the tire products, reduce the trial times of the tire, shorten the tire research and development period and lower the tire research and development cost.

Description

technical field [0001] The invention relates to a method for simulating the building process of a radial tire, which can realize the computer simulation of the water tire forming of the radial tire. Background technique [0002] In the process of tire construction design, the trial-and-error method based on experience is often used to judge whether the structural shape and size of the components are reasonable. This method has the disadvantages of narrow application range, low precision, and small amount of information. Especially for the design and manufacture of tires with complex structures, new materials or new processes, the number of tests using this method increases and the errors are large, and ideal results are often not obtained, resulting in long product development cycles and huge waste. [0003] In recent years, computer simulation has been widely used in the field of tires, and has been successfully applied to tire performance analysis, vulcanization analysis, ...
