Modal Analysis on Laboratory Scale Vibratory Bowl

Vibratory surface finishing is commonly used as a suitable method for surface finishing of components. Understanding the physics behind the system is becoming essential to optimize the process. Therefore, in the first place, it is also essential to investigate its structural response under vibrational loads. In the present study modal analysis is carried out experimentally and numerically on a laboratory scale vibratory bowl made of aluminum alloys. The numerical natural frequencies and mode shapes were extracted using finite element analysis and later were calibrated referring the experimental modal analysis using impulse hammer technique with single axial accelerometer. Furthermore, frequency response analysis has been carried to understand the vibratory bowl response under loaded condition.
