Abstrect: A new integral equation method is given to solve the vibration characteristics of sector plates by combining the approach of integral equations and the Fourier series method in structure mechanics. The results obtained show that this method is not only simple and effective, but also has high precision and good stability. Furthermore, it provides a reliable premise for the vibration analysis of more complex sector plates.
