| Abstract: |
| With 255/30R22 tire as an example，a finite element model of the vulcanization process was established using ABAQUS software.The vulcanization process was firstly simulated without considering the reaction heat，and then simulated with reaction heat loaded by HETVAL.The tempe rature fields were obtained，respectively，and the vulcanization degree field for the simulation consi dering the reaction heat was obtained with subroutine UVARM.The results showed that， during tire curing process，the vulcanization reaction heat affected the peak position of the curing temperature curve，but had very little impact on the final temperature.Taking consideration of reaction heat could better simulate the real tire vulcanization process.The curing temperature of the thin rubber part was always higher than that of the thick rubber part，and the vulcanization degree of thin rubber part was also higher.It was found that post cure was important and it was necessary to further improve the traditional vulcanization process. |
