| ABSTRACT |
|
The tire building process is a key part of tire manufacturing, serving as a bridge between the construction
design and the finished tire, and the bladder is the core component to complete the shaping process. With the help of finite
element method, the tire building process can be effectively reproduced, which help to carry out targeted problem solving and
solution design. In this paper, the numerical simulation method is used to study the 205/55R16 radial tire building process,
and the reliability of the simulation method is verified by comparing simulated green tire and its test section; then the shaping
simulation model incorporating the bladder is established and compared with the finished tire parts to illustrate the reliability;
On this basis, the influence of bladder parameters was analyzed by orthogonal design of experiment and simulated annealing
optimization algorithm, the sensitivity of different parameters was obtained, the bladder parameters were optimized;
compared with the bladder with original parameters, the optimized bladder effectively reduced the stress by 44.67 % and
55.54 % , while significantly improving the contact force between the bladders and the green tire. The results of the study
provide a good methodological basis and theoretical guidance for tire design, manufacturing and bladder optimization. |
