The method includes: obtaining the half-length of the tire's contact footprint, the first characteristic parameter and the second characteristic parameter; based on Solve the first tire theoretical model parameter model, determine the first tire theoretical model parameters according to the half-length of the contact patch and the first characteristic parameters; solve the model based on the second tire theoretical model parameters, and determine the first tire theoretical model parameters according to the half-length of the contact patch, bristle stiffness and second characteristic parameters Determine the model parameters with the second tire theory. The method provided by the embodiment of the present invention establishes a solution model for each model parameter to be identified, and solves each model parameter step by step. Compared with the overall identification of the prior art, the step-by-step independent solution reduces the randomness of the result. That is to say, the accuracy of the model parameters is improved, and the extension ability and prediction ability of the 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...
