As the tire industry continues to develop, Zhongce Rubber Group Co., Ltd. has once again become the focus of the industry with its outstanding innovation capabilities and technical strength.
According to news on April 19, information from the State Intellectual Property Office shows that Zhongce Rubber has applied for a patent called “Multi-objective optimization method and system for electric vehicle tire bead durability”. The application publication number is CN121881880A, the application number is CN202610352840.7, the application publication date is April 17, 2026, and the application date is March 23, 2026.
This patent focuses on the field of electric vehicle tire simulation design technology and is of great significance.
This patent forms a sandwich layer of the carcass, apex rubber, and turn-up side carcass, establishes the coupling boundary between the constraint zone/active zone and the rim, applies cyclic loads according to the 4-15 Hz working condition; extracts the S11 and interface shear amplitudes along the turn-up path, and determines the neutral plane and its stability based on the minimum strain amplitude surface.
Using Δh, layer thickness b1 – b3, modulus σ1 – σ3 and cord parameters c/ρ/w as variables, evolutionary/Bayesian optimization is used to minimize S11 and shear amplitude and minimize the neutral plane variance, and output the nominal values of the parameters and the tolerance window.
This approach combines precision and efficiency to suppress compression and shear peaks, improve bead durability, and shorten design cycles.
