164645 - Robust Computational Modeling of Free Piston Linear Generators: A FEMM and MATLAB/Simulink Approach 

Abstract: 

The Free Piston Linear Generator (FPLG) is a cutting-edge system for energy conversion that integrates the principles of internal combustion engines with those of linear electric generators. This innovative approach promises several advantages, such as enhanced efficiency and simplified mechanical design, making it a strong contender for use in automotive and industrial sectors.

This research delves into the development and validation of the FPLG's electromagnetic component using Finite Element Method Magnetics (FEMM) software alongside Matlab/Simulink. The primary aim is to establish a dependable computational model that can accurately replicate the performance and behavior of FPLGs under various operational scenarios.

FEMM was chosen for its robust ability to tackle complex electromagnetic challenges, which are essential for precise FPLG modeling. The model was carefully crafted, incorporating detailed geometries and material characteristics. Key metrics such as magnetic flux density, electromagnetic forces, and piston motion dynamics were calculated and examined.

To validate the model, an extensive comparison with experimental data from existing literature was performed. The findings revealed a strong correlation between the simulated results and experimental data, confirming the model's precision and reliability.

The study's outcomes emphasize the potential of the developed model as an effective tool for designing and optimizing FPLGs. Future research will aim to refine the model further by including additional components like power electronics. This study lays a solid foundation for the advancement of FPLG technology and contributes to the broader field of sustainable energy solutions.
