Recently, public information from the State Intellectual Property Office shows that the invention patent “A rapid finite element meshing method for tread patterns with shoulder arcs” filed by Triangle Tire and South China University of Technology has officially entered the publication stage. This patent optimizes the entire finite element meshing process for special treads with shoulder arc structures, greatly improving the simulation efficiency and accuracy of the research and development process. It is another breakthrough in the field of R&D digitization in the domestic tire industry.

According to patent disclosure information, this technology axially maps the inner and outer contours of the tread pattern meridian containing shoulder arcs, establishes hierarchical lines within the mapped outline, completes the two-dimensional grid division and axially restores it to a three-dimensional surface mesh, and then solves the three-dimensional node coordinates of the non-arc areas and arc areas through corresponding algorithms, and finally generates and actual
The single-pitch tread pattern finite element mesh with a completely matching shape completely solves the common industry problems of long time-consuming and substandard accuracy in the previous arc structure tread meshing. The meshing efficiency is improved by more than 40% compared with the traditional solution. At the same time, the mesh quality has also been significantly optimized, which can provide more reliable basic data for subsequent tread performance simulation and structural optimization.

As a core enterprise in the domestic tire industry, Triangle Tire has been deeply involved in tire R&D and manufacturing for many years. Its products cover multiple categories such as passenger tires, commercial vehicle tires, and special engineering tires. With its stable quality and leading technical strength, its products are exported to more than 180 countries and regions around the world and have been widely recognized by the global market.
In 2025, Triangle Tire achieved operating income of 9.821 billion yuan, ranking 7th in the domestic tire industry, and net profit of 923 million yuan, ranking 6th in the industry. Both revenue and profit levels are higher than the industry median, showing strong development resilience.
In addition to the grid division patent disclosed this time, Triangle Tire has continued to increase investment in research and development in recent years. The patent layout covers the entire industry chain such as material formula, production process, intelligent detection, and appearance design. In the past year alone, more than 50 patents have been disclosed or authorized, covering high-load dump truck tire pattern structure, tire vulcanization process optimization, AI visual defect detection, rubber composition formula and other technical directions. It not only provides technical support for the company’s own product iteration, but also promotes the improvement of the overall technical level of the domestic tire industry.
As the global tire market’s demand for high-end and differentiated products continues to grow, domestic tire brands with core technological advantages will gain a higher market share in the global market.
