rings fully meets the design requirements. characteristics, playing a pivotal role in optimizing the
structural stress of radial aircraft tires and reducing tire weight.
3 Conclusion However, the structural stress analysis of circular bead wire
Currently, high-performance radial aircraft tires have still requires continuous research and exploration, particularly
widely adopted circular cross-section steel belts. In China, only under dynamic loading conditions, where there remains
a handful of companies, such as Shandong Shengtong Steel significant room for further study and exploration.
Cord Co., Ltd. and Shandong Daye Co., Ltd., are capable of In China, with the gradual breakthroughs in key projects
producing circular steel belts. Harbin Institute of Technology related to aviation tires, the mass production of aviation
Hongtu Rubber and Plastic Technology Co., Ltd. has jointly tires urgently requires a large supply of supporting circular
developed circular steel belt production equipment with Harbin steel wire rings, which brings about the application demand
Institute of Technology, which can produce circular steel belts for specialized equipment for producing circular steel wire
of various specifications and sizes, supplying domestic aircraft rings. At the same time, it provides a platform for equipment
tire production and research enterprises. suppliers involved in technological breakthroughs in this field
The circular cross-section bead wire possesses to engage in research and development, manufacturing, and
high tensile strength and exhibits no stress concentration supply.
