摘要:

为探究摩擦副在瞬时高应力启动过程中的静动摩擦转化特性,搭建了模拟工况静动摩擦的测试装置,开展了GCr15SiMn/GCr15摩擦副的静动摩擦转化实验和仿真,研究了接触应力和加速度对静动摩擦转化过程的影响规律。研究结果表明,随着接触应力的增大,微凸体发生塑性变形,减弱了微凸体间的互锁作用,导致静动摩擦因数减小;随着加速度的增大,微凸体间的互锁作用增强,导致静摩擦因数增大,但动摩擦因数无明显变化。

关键词: 启动过程, 静动摩擦, 接触应力, 加速度, 球盘摩擦副

Abstract:

To investigate the statictodynamic friction transition characteristics during instantaneous highstress startup, a test apparatus was constructed to simulate friction behavior under operating conditions. Experiments and simulations were conducted on a GCr15/GCr15SiMn friction pair, and the effects of contact stress and acceleration on the friction transition were examined. The results show that increasing contact stress causes significant plastic deformation of asperities, weakens the interlocking effect between them, and reduces both static and dynamic friction coefficients. Increasing acceleration enhances the asperity interlocking effect and raises the static friction coefficient, whereas the kinetic friction coefficient remains relatively unchanged.

Key words: startup process, static-to-dynamic friction transition, contact stress, acceleration, balldisk friction pair
