Question

an undulated surface that is designed to reduce friction by eliminating wear particles from the sliding interface. The interface is subjected to normal force N. The sliding speed is so low that the interfacial temperature rise is negligible relative to the melting point of the material. We are planning to use metals for the sliders.

a. Determine the optimum dimensions of the undulated topography.

b. Discuss the consequence of deviating from the optimum geometry.

Answer 1

a) Modeling of the tribological is a complex and difficult task. It is most important for all stages of the life cycle of machine and machine component.

So the design of parts minimum contact between two bodies and for maintaining friction coefficient between two bodies use suitable lubricant according to material properties. Stability depends on a part geometry, so create parts like that way equal normal force transfer to each other and maintain the stable condition during sliding. Using this condition easily design a part. In this part friction is minimum and we eliminate wear particles from the sliding interface

b) If the geometry is not optimum that time we face some problem stability not exist and a contact area between two parts are increases and normal force does not balance proper way.

Geometry is the main parameter it plays a crucial role in this process and the second important parameter is the area of contact between two bodies or lubrication.
