摘要

摘要: 把轮胎硫化热传导作为轴对称问题处理,从用热流密度表示的轴对称问题的有热源的非稳态热传导方程出发,建立了复合材料轴对称结构热传导分析有限元列式,进而结合轮胎硫化生热机理及变化的轮胎硫化加温历程研制了一个较全面地考虑胎硫化过程复杂性的有限元分析软件。用该软件对某轮胎的硫化过程进行了仿真计算,得到了一系列的数值计算结果。可以看出这些数值计算结果是符合实际的。

Abstract: Tire curing heat transfer is treated as an axisymmetric heat transfer problem. By using Galerkin's method, the finite element formulation of the axisymmetric heat transfer problem is carried out for composite materials from the heat transfer differential equations expressed by heat fluid density. The rubber curing dynamics model and real tire curing temperature history are further combined with the finite element formulation to develop a finite element analysis software for numerical simulation of the tire curing process. Finite element analysis of a tire curing process shows that numerical simulation results given by the software are correct in tendency.
