| 针对厚制品V形橡胶弹簧模具型腔温度分布不均匀导致硫化程度不一致以及硫化时间设计不当的问题，通过基于硫化传热和硫化动力学模型的数值模拟，计算模具型腔温度场分布和V形橡胶弹簧芯部硫化程度，提出增加中模加热圈并确定其适宜加热温度，在考虑后硫化效应的情况下确定V形橡胶弹簧最佳硫化时间。通过溶胀指数和垂向刚度试验证明V形橡胶弹簧硫化时间仿真结果的准确性和可靠性。 |

| 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. |
