Abstract

The invention is applicable to the technical field of computers, and provides a tire theoretical model parameter determination method, device and equipment and a storage medium. The method comprises the following steps: acquiring the half length of a grounding mark, a first characteristic parameter and a second characteristic parameter of a tire; based on the first tire theoretical model parametersolving model, determining a first tire theoretical model parameter according to the half length of the grounding mark and the first characteristic parameter; and solving a model based on the secondtire theoretical model parameter, and determining a second tire theoretical model parameter according to the grounding print half-length, the bristle rigidity and the second characteristic parameter.Based on the method provided by the embodiment of the invention, a solving model is established for each to-be-identified model parameter, and each model parameter is solved step by step, so that therandomness of a result is reduced compared with overall identification and step-by-step independent solving in the prior art, the accuracy of the model parameters is improved, and the extension capability and the prediction capability of a tire theoretical model are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a tire theoretical model parameter determination method, device, equipment and storage medium. Background technique [0002] In the tire mechanical performance experiment, it is usually necessary to construct a tire model. The tire brush model is a classic model in tire mechanics, which simplifies the tire into "elastic tread and rigid carcass". However, the traditional brush model does not consider the elasticity of the carcass, resulting in insufficient precision in expressing the mechanical properties of the tire. On the basis of the traditional tire brush model, scholars at home and abroad have further considered the complex elastic deformation of the carcass, established a more accurate tire mechanics model, and analyzed the steady-state lateral deflection, longitudinal slip characteristics, and tires under lateral deflection and longitudinal slip composite wor...
