Tire structure design method and application thereof

Abstract

The invention discloses a tire outline and carcass simulation design method, and particularly relates to an all-steel meridian (TBR) tire. The tire stress and deformation capacity, the tire body contour, the tire tread contour and the tire balance contour are considered, and the purpose of improving the durability of the tire is achieved.

Description

technical field [0001] The invention belongs to the field of tire structure design methods, in particular to a simulation design method for an all-steel radial (TBR) tire outline and carcass. Background technique [0002] The tires of transport vehicles in our country are usually used under abnormal conditions such as overload, high air pressure and partial load, so the contour deformation of the tire increases, and early signs of damage to the shoulders and the surrounding parts of the bead (referred to as the bead part) are prone to occur. The contour of the carcass constitutes the closed cavity inside the tire, and its contour shape has a great influence on the stress state and overall performance of each part of the tire. Stress concentration is the first important factor affecting the durable damage of the tire. In order to reduce stress concentration, the existing methods include reducing the thickness of the thicker part of the tire, reducing the height of the turn-up...

AI Technical Summary

Problems solved by technology

However, because the traditional inner contour of the tire is generally designed with multi-section arc experience, it lacks the consideration of the dynamic balance state of the tire, resulting in poor tire durability.

At the same time, the durability of the tire is directly related to the stress state of its internal materials. It is difficult to obtain the stress and strain values ​​inside the material by traditional experimental methods.
