On December 4, 2014, the Department of Science and Technology of Henan Province organized seven professional experts in Henan Province Institute of Chemical Industry, Henan Provincial Institute of Chemistry, Zhengzhou University, Henan Polytechnic University and other universities and research institutes to complete the "low noise" of Fengshen Tire. The "R&D of All-Steer Truck Radial Tire" project identified the scientific and technological achievements. After being questioned, defended by the appraisal committee, and on-the-spot investigation, the appraisal committee unanimously believed that the technical innovation of Fengshen Tire's “low noise all-steel radial truck tire †technology innovation was obvious and reached the international advanced level. At the appraisal meeting, Fengshen Tire technicians gave a detailed introduction on the innovation of the project, the level in the industry, its economic benefits and social benefits. According to reports, the development of a low-noise, all-steel radial truck tire has been optimized through software and a special structure has been added to the carcass to reduce the response of the carcass to vibration excitation and to reduce the vibration and noise of the tire. Bionic non-smooth structure is arranged inside to improve tire aerodynamic noise and tire aerodynamic noise is reduced; in formula design, orthogonal optimization design is adopted, the best green environmental protection formula is selected, physical and mechanical properties of tread rubber are improved, and tire resistance is improved. Grinding performance. The product performance meets the requirements of gb9744-2007 standard and has passed the EU certification. The products are exported to Europe and the United States, have good noise reduction and handling performance, and have broad market prospects, with significant economic and social benefits.
