| Abstract: |
| Aiming at the problem of inconsistent vulcanisation degree caused by uneven temperature distribution in the cavity and sloppy design of vulcanisation time for V-shaped rubber springs, numerical simulation based on vulcanisation heat transfer and vulcanisation kinetic model calculates the temperature field distribution in the cavity of the mould and the vulcanisation degree of the rubber, the strategy of increasing the heating ring in the middle mould and determining the optimal temperature setting were proposed, and the optimal vulcanisation time was determined by considering “thepost-vulcanisation effect”. Finally, the accuracy of the simulation results is proved by the results of swelling and vertical stiffness test.Aiming at the problems of inconsistent vulcanization degree caused by uneven temperature distribution in the mould cavity and improper design of vulcanization time for thick product—the V-shaped rubber spring，by numerical simulation based on vulcanization heat transfer and vulcanization kinetic model，the temperature field distribution in the mould cavity and the vulcanization degree of the core of the V-shaped rubber spring were calculated to propose increasing the heating ring in the middle mould and determine its optimal temperature，and the optimal vulcanisation time of the V-shaped rubber spring was determined by considering the post-vulcanisation effect.The accuracy and reliability of the simulation results for the vulcanization time of the V-shaped rubber spring were proved by swelling inedx and vertical stiffness test. |
