摘　　要：以斜平面X1188型号的轮胎活络模具为例,借助ABAQUS有限元分析软件,对活络模具进行整体式顺序热力耦合分析,得出活络模具在硫化过程中花纹块的应力位移分布、花纹块内表面和侧面取点应力-位置曲线图。通过对活络模具结构改进和优化,改变花纹块口径高度、花纹块与花纹块间的贴合面宽度,花纹块与弓形座采用不同的配合方式,比对不同条件下花纹块的应力、位移有限元分析结果,得出应力位移分布和变化规律,可为模具设计提供参考依据。In this paper,the inclined plane X1188 type tire active die is taken as an example,and the whole sequential thermodynamic coupling analysis of the active die is carried out with the help of ABAQUS finite element analysis software.The stress displacement distribution of the pattern block and the stressposition curve of the inner surface and side of the pattern block are obtained during the vulcanization process of the active die.Through the adjustable die structure improvement and optimization,change the pattern block size height,pattern and decorative pattern blocks of the joint surface between width,pattern blocks and bow adopt different ways of cooperation,the comparison of different pattern block under the condition of the stress and displacement of the finite element analysis results,it is concluded that the stress and displacement distribution change law,can provide the reference for die design.
