GUI-Based Rolling Bearing Characteristic Frequency Calculation

Using MATLAB's Graphical User Interface (GUI) framework, this application enables efficient calculation of rolling bearing characteristic frequencies. The implementation involves parameter input validation through callback functions and executes frequency computations using bearing dynamics equations. The core algorithm processes geometric parameters like bearing pitch diameter, ball diameter, contact angle, and rotational speed to derive four characteristic frequencies: Fundamental Train Frequency (FTF), Ball Pass Frequency Outer race (BPFO), Ball Pass Frequency Inner race (BPFI), and Ball Spin Frequency (BSF). Beyond frequency calculation, the GUI integrates additional modules for vibration analysis and fault diagnosis, utilizing signal processing techniques like FFT and envelope analysis for bearing condition monitoring. The interface employs MATLAB's App Designer components for parameter input fields, calculation buttons, and result visualization panels. This integrated approach facilitates comprehensive bearing performance analysis and optimization through an intuitive user interface that simplifies complex bearing dynamics computations.
