Prediction Model of the Fusion Microzone on Sliding Contact Surface

Abstract EN

The current paper is motivated by the need to understand the factors in generating the fusion microzone in sliding systems.

The objectives are to analyze the different elements' varied influence on the engineering surface's temperature rise.

The current paper developed the prediction model based on the thermal conduct theory.

A solution based on the Green's function method is combined with the grid method for calculating the temperature rise and distribution.

The research indicates that: frictional heat is closely related to the sliding velocity, its value is in proportion to the sliding velocity; the thermal properties of the material are one of the key points to decide the temperature rise; the load is another main factor in increasing the temperature rise; comparing with other elements, the roughness may be the least effective to the temperature rise.
