The tribophysics of the cylinder liner—piston rings in an internal combustion engine is a typical tribological system with the reciprocating motion and the impacting motion. 内燃机缸套——活塞环摩擦副系统是一个集往复、冲击于一体的典型的摩擦学系统。
Tribology is the study of science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is a branch of mechanical engineering and materials science.
