Problems solved by technology

At the same time, due to the curved shape of the tread, during the tire building process, the belt layer will bend, which will cause angle changes
The existing design method does not fully consider the expansion effect of the belt layer and the properties of the steel wire material, resulting in differences between the simulation design method and the actual situation

Embodiment Construction

[0034] Assuming that the bone material has a certain elongation during the process of the belt part from the building drum to the finished tire, the elongation rate is ε, and the formula for the angle change of the belt before and after forming is derived as follows:

[0035] A 1 B 1 =dL=(1+ε)dL 0

[0036]

[0043]

[0044]

[0045] N is the number of wires, s 0 and s are the distances between the two skeleton materials before and after forming, respectively. Simulations that take into account the effects of belt expansion are achieved via the expansion rate, drum diameter and part thickness.

[0046] Import the parameters, form a two-dimensional structure diagram through the processing software TYABAS 3.0, and then convert it into a three-dimensional simulation model. In the comparison test, the ...

Abstract

The invention discloses a tire simulation design method, in particular to a simulation design method of an all-steel meridian (TBR) tire belt ply, which not only considers the influence of process parameter expansion rate on tire performance and applies a belt ply ascending equation in the simulation process, but also considers the influence of different pre-strain zero-degree belt ply constitutive curve models on tire performance.

Description

technical field [0001] The invention belongs to the field of tire design methods, and in particular relates to a simulation design method for a belt layer of an all-steel radial (TBR) tire. Background technique [0002] Due to the heavy load of all-steel radial tires, damage to the tire shoulder and bead position occurs frequently. However, the tires of transport vehicles in my country are usually used under abnormal conditions such as overload, high air pressure, and partial load, and the contour deformation of the tire increases. , prone to signs of early damage to the tire shoulders and the surrounding parts of the bead (referred to as the bead part), so solving the durability damage of the tire is the core technical problem that the company needs to solve urgently. [0003] The belt layer is the core issue in the structural characteristics of radial tires. Since the belt layer is the main force-bearing part of the radial tire, it determines the strength and profile of the...
