摘　　要：以多接触面轮胎定型硫化机立柱与夹紧块主承载接触面为研究对象,考察接触表面质量即摩擦因数对主承载接触面之间微动行为的影响,利用有限元分析软件HyperMesh和Ansys对接触面微动情况和应力进行模拟分析。结果表明:当摩擦因数不大于0. 15时,硫化机立柱与夹紧块接触面之间的微动位移、接触点应力变化很小;当摩擦因数大于0. 3时,随着摩擦因数的增大,微动位移显著增大,但是接触点应力有所下降。硫化机立柱与夹紧块的主承载接触面之间摩擦因数应不大于0. 15。For main bearing contact surface between pillar and clamping block in the tire shaping and curing press with multi-contact surfaces,the influence of the quality of contact surface,that is,the friction coefficient on fretting behavior was investigated,and the fretting and contact surface stresses of the curing press were simulated and analyzed by using the general finite element analysis software Ansys. The analysis results showed that the variations of fretting displacement and the contract stress in the interface between pillar and clamping block was small when the friction coefficient was less than 0. 15. When the friction coefficient was larger than 0. 3,the fretting displacement increased significantly and the contact stress decreased with the increasing of friction coefficient. The friction coefficient of the main bearing contact surface between pillar and clamping block should not be larger than 0.15.
