【摘要】 研究了385/55R22.5HN809全钢载重子午线轮胎的成型过程,并利用ABAQUS软件,模拟了成型过程的主鼓部件贴合、辅助鼓部件贴合、半成品胎成型和花纹挤压成型4个工况,得出了成品胎的材料分布图,接着将仿真得出的结构和实际轮胎的断面结构进行了对比分析,最后对胶料厚度的仿真结果进行了分析。结果表明:仿真结构和实际结构具有很好的一致性,可以为轮胎的结构设计和施工设计提供指导。模型中,采用广义Maxwell模型描述混炼胶的力学行为,采用Rebar模型模拟橡胶帘线复合材料。更多还原

【Abstract】 In this paper,the building process of 385/55R22.5HN809 all-steel radial truck tire is studied,where ABAQUS is used to simulate the building process considering four building conditions including gluing of components on main drum,gluing of components on auxiliary drum,semi-finished tire and tire pattern.The material distribution of the finished tire is established and compared with that of the real tire,and the thickness of rubber compounds is analyzed.The analysis results indicate that the simulated structure has a good agreement with the real structure,and it can be used to guide tire construction and structure design.In the finite element model,the generalized Maxwell model is used to describe mechanical behaviour of rubber compounds,and the Rebar model is used for cord-rubber composites.更多还原
