Automated Design Optimization of Rotors for External Gear Hydraulic Pumps

External gear pumps are widely utilized in various applications due to their simplicity, robustness, and versatility. This thesis presents the development of a MATLAB application designed to optimize the dimensions of external gear pump gears under specific dimensional constraints, with a primary focus on achieving the required pump displacement. The application efficiently calculates essential gear parameters, such as module, number of teeth, and center distance. It also evaluates the flow ripple, a critical factor influencing pump behavior and noise levels. The optimization process incorporates user-defined constraints, ensuring that the resulting gear design meets the operational requirements, in case the input parameters cannot achieve a solution within the constraints, it offers the closest possible solution . Additionally, the application includes can be used to automatically generate drawings of the optimized gears. These drawings can be visualized on the app or be exported in formats compatible with leading CAD software, facilitating seamless integration into the design and manufacturing workflow. Also they have great utility for simulation in CFD software. The proposed MATLAB application permits rapid iteration in simulation environments instead of experimentally obtaining the pump characteristics. This will be an extremely useful tool for research and rapid prototyping work, saving time and resources.
