TRIBOMECHANICAL SYSTEMS IN DESIGN

Abstract

The usual tribomechanical systems that are used in the process of development design are presented in this paper. Complex processes of friction and wear at contact surfaces are done within those tribomechanical systems. The basic tribological characteristics of tribomechanical systems are friction and wear that are the main causes of system structure alteration, energy and material losses. As natural processes, friction and wear depend on large number of factors such as: system structure, exploitative conditions (speed and load), mechanical and chemical properties of material, lubrication characteristics, environment aggressiveness, temperature, topography of surfaces in contacts, mechanical processing (pre- and post-processing) an so on. The number of influential factors and complexity of their interactions in which variation of one parameter caused chain alterations of different parameters complicate the quantification of theirs influences. Those are the reasons for present insufficiency of systematic information about tribological characteristics of tribomechanical systems.
