| Abstract: |
| A systematic method for finite element analysis of rubber curing process was presented.The thermal conductivity and specific heat capacity varying with temperature and state-of-cure were considered，and the accuracy of five kinetics models such as Nth-order，Piloyan，Kamal-Ryan，Kamal-Sourour and Rafei model were evaluated to give the optimum kinetics model according to the curing curves.The induction period was described by dimensionless parameters combined with Arrhenius function.Taking rubber piston for washer as an example，ABAQUS software and user subroutine UMATHT were used to calculate the curing model and analyze the induction time，temperature and state of cure of the piston during the curing process.The results showed that the finite element method was suitable to provide cost effective and practical prediction for rubber curing process. |
