Fuel economy has always been a major issue for the automotive industry due to environmental concerns. In particular, it is known that only 5-20% of the energy generated in a car that mainly uses an internal combustion engine is converted to increase fuel efficiency, many methods have been proposed. Among these methods, weight reduction is most commonly used because it is the simplest and cheapest. Weight is always the main reason for energy consumption, therefore, reducing weight is the best way to increase fuel efficiencywhile simultaneously saving on material costs. To reduce the weight of a compressor, material substitution isused. However, aluminum (a lighter metal substitute) is more fragile than steel, therefore, structural stabilitymust be verified through testing. In this paper, we performed a 3D analysis to investigate whether aluminumcan be used without compromising structural stability. Our investigation included static analysis and thermalanalysis. As a result, we found that an aluminum swash plate can be safely applied on a shaft instead ofsteel; it reduces weight while maintaining stability that is equal to or better than steel.
