AI Technical Summary
Existing technologies lack effective methods to realistically simulate and test the interfacial mechanical properties of the tire's steel cord ply and rubber ply, making it impossible to accurately evaluate the matching of parameters such as rubber formulation, belt layer angle, and steel cord thickness in tire design.
Design a sample device including an upper template, a lower template and a middle template. A cavity is set in the middle template, and samples of rubber layer and steel cord layer are placed in the cavity and connected by cellophane to simulate the interlayer structure of tire design and to test the interface mechanical properties.
This device can more realistically simulate tire structure, evaluate the interface performance between steel cord and rubber layers, reduce interface delamination during tire use, and provide data support for the design of high-quality tires.
