Tire finite element simulation analysis data post-processing method

Abstract

The invention relates to the field of finite element simulation analysis of tire design and development, in particular to a tire finite element simulation analysis data post-processing method. Firstly, the tire is equally divided into 180 sections in the circumferential direction, and in the process that the tire rolls for one circle, the stress state of any section rolling for one circle can be selected to represent the stress state of the whole tire rolling for one circle; secondly, 180 three-dimensional tire sections are subjected to data mapping and converted into 180 two-dimensional plane tire models, and later data processing, display and storage are facilitated; then, data association is carried out on units at the same position of each two-dimensional tire model, when data of a certain unit rolling for a circle is extracted, the unit is directly selected, all data of the unit of the circle can be automatically selected, 180 units of the circle are equivalent to 180 frames of any unit rolling for a circle, therefore, the data of each course of the solved unit in a rolling circle can be directly extracted.

Description

technical field [0001] The invention relates to the field of finite element simulation analysis of tire design and development, in particular to a method for post-processing tire finite element simulation analysis data. Background technique [0002] At present, the vigorous development of the automobile industry has greatly shortened the replacement cycle of tire products. In order to adapt to this trend and improve the mechanical properties of tires in a more targeted manner, many tire companies have introduced tire finite element analysis in the process of tire design and development. Technology, the simulation analysis of tire inflation, loading and steady-state rolling, etc., among which, the steady-state rolling analysis is an extremely important simulation analysis content. [0003] The processing of a large amount of data after the steady-state rolling analysis and calculation is very cumbersome. The main problems in the current data post-processing link: 1.

Problems solved by technology

[0003] The processing of a large amount of data after the steady-state rolling analysis and calculation is very cumbersome. The main problems in the current data post-processing link: 1. For the tire steady-state rolling simulation analysis and calculation results, it is impossible to visually view the force state of the tire model rolling one week ; 2. To extract the history data of a certain unit in the tire for one week, it is necessary to select all the data within one week of the unit, and the data extraction is very inconvenient; 3. A large amount of result data requires high storage space
