Features: Tangential micro-motion, radial micro-motion, rolling micro-motion, and torsional micro-motion are four basic micro-motion operational modes. However, most research to date has focused on tangential micro-motion, and studies on the combination of two basic micro-motion modes have not yet been reported. Research on radial and composite micro-motion modes holds broad engineering application prospects in many fields such as railways, automobiles, aviation, aerospace, nuclear reactors, telecommunications, power systems, and human implantable devices. It not only has scientific significance in exploring the unknown but also provides important guidance in combating industrial micro-motion damage. The main work completed and the main conclusions drawn in this thesis are as follows:
(1) Developed a new radial micro-motion test apparatus, realistically simulating radial micro-motion and laying an experimental foundation for radial micro-motion research.
(2) Systematically studied the operational and damage mechanisms of radial micro-motion.
(3) Successfully achieved the combination of the two basic micro-motion modes—tangential and radial—for the first time.
(4) Systematically studied the operational and damage mechanisms of composite micro-motion.
(5) Investigated the variation patterns of damage mechanisms in tangential, radial, and composite micro-motion as the relative tilt angle of the contact pair changes.
