A functionally graded thermal barrier coating (TBC) on brake discs effectively reduces braking temperatures. This study models heat generation in disc-pad systems with TBCs, showing significant temperature reduction.
Area of Science:
- Tribology
- Materials Science
- Thermal Engineering
Background:
- Braking systems generate significant heat due to friction.
- Thermal barrier coatings (TBCs) can mitigate heat buildup.
- Functionally graded materials (FGMs) offer tailored thermal properties.
Purpose of the Study:
- To develop a mathematical model for heat generation in a disc-pad braking system with an FGM TBC.
- To analyze the thermal behavior of the braking system under friction.
- To evaluate the effectiveness of FGM TBCs in reducing braking temperatures.
Main Methods:
- Developed a three-element mathematical model of the disc-pad system.
- Assumed perfect thermal contact between coating and pad, and coating and substrate.
- Obtained exact solutions for constant and linearly descending friction power.
- Performed numerical analysis using specific material combinations.
Main Results:
- The mathematical model accurately predicts heat generation during braking.
- The FGM TBC effectively absorbs frictional heat.
- Numerical analysis confirmed significant temperature reduction with FGM TBC application.
Conclusions:
- Functionally graded thermal barrier coatings on brake discs are effective in reducing braking temperatures.
- The developed model provides insights into the thermal dynamics of braking systems.
- FGM TBCs represent a promising approach for enhancing braking system performance and durability.
