摘要

硫化参数显著影响橡胶密封件的性能和制造过程的节能，这需要工艺参数和硫化特性之间的关系。基于橡胶密封材料的硫化动力学，建立并求解了硫化过程的瞬态热化学耦合有限元模型。详细考虑了硫化过程中导热系数和比热容的变化。研究了模具温度、加热时间、橡胶密封件形状、截面尺寸等操作和结构参数对硫化特性的影响。最后，对橡胶密封件的硫化生产提出了可行的建议。该研究有望对橡胶密封件的硫化过程进行精确的参数设计和控制。

NUMERICAL ANALYSIS OF HEAT TRANSFER AND CHEMICAL REACTION COUPLING IN THE RUBBER SEAL VULCANIZATION PROCESS

Vulcanization parameters significantly affect the performance of rubber seals and the energy savings of the manufacturing process, which require a relationship between process parameters and vulcanization characteristics. Based on the vulcanization kinetics of rubber seal materials, a transient thermochemical-coupled finite-element model of the vulcanization process was established and solved. Changes in thermal conductivity and specific heat capacity during vulcanization were considered in detail. The effects of operational and structural parameters, such as mold temperature, heating duration, and rubber seal shape, cross-sectional dimensions on vulcanization characteristics were investigated. Finally, feasible suggestions for the vulcanization production of rubber seals are discussed. The study is expected to design parameters and control the vulcanization process of rubber seals accurately.
