Embodiment

[0023] figure 1 It is the implementation flow chart of the processing method of the present invention, below with the example that a tire tread pattern normal direction stiffness contour is generated, carry out concrete description by processing method and process of the present invention.

[0024] According to the present invention figure 1 As shown in the process, the original design drawing of the tire pattern is imported into the computer-aided design program AutoCAD. Curve information, only the geometric elements related to the tread pattern are retained, and the block boundaries are connected end to end during the cleaning process. eventually get as image 3 As shown in the tire tread pattern structure diagram, export it to a data file in DXF format.

[0025] Next, read the DXF file information. In the DXF file, geometric information such as straight line segments and arcs are stored in a fixed format. Straight line segments are stored according to the coordinates of ...

Abstract

The invention relates to a method for quickly generating a tire tread pattern normal stiffness cloud diagram, a method for designing a tire tread by using the same and a designed tire. According to the method, the computer programming language C++ is adopted to quickly generate the pattern normal stiffness cloud diagram, a tread pattern two-dimensional DXF file is used as an input file, and finally the stiffness is displayed in the form of the cloud diagram. By means of the method, the work efficiency is multiplied, analysis results can meet the requirements of users, and the method can be used for guiding tire pattern design workers to improve design schemes and reduce the design cycle.

Description

technical field [0001] The invention relates to a method for quickly generating a tire pattern normal stiffness cloud map, which can be used in tire design and analysis research institutes to conveniently and quickly determine the distribution of the tread pattern normal stiffness. Background technique [0002] The tire pattern, also known as the tread pattern, is the direct contact part of the tire interacting with the road surface. The design of the tread pattern is the most complex among the four elements of tire design, and it is also the most important. It not only determines the use characteristics of the tire, but also determines the grip, drainage and noise reduction of the tire. In the design of pattern structures, stiffness is an indicator that cannot be ignored. Stiffness is used to measure the ability of materials or structures to resist elastic deformation when stressed. The greater the stiffness, the smaller the deformation. On the contrary, the smaller the st...
