Modal analysis is a procedure through which we will study the vibrational properties and dynamic behavior of the back of the drum of a drying machine. The primary challenge involves identifying modal parameters, including natural frequencies, mode shapes, and system damping. We will first approach this with numerical analysis using a student version of the simulation software Ansys and then compare it with the results of the Experimental Modal Analysis. We obtained some comparable natural frequencies and mode shapes. Additionally, we observed possibilities for improvements such as the placement and number of measurement points and the optimization of the 3D model.
