This paper presents a numerical simulation procedure for dynamic response analysis of industrial grinders containing viscoelastic components that contribute significant amount of damping to the total system response. The approach presented in this paper consists of: (a) obtaining undamped modal characteristics of the structure, (b) expressing the normal and tangential dynamic loads applied to each grinding segment through Fourier series, (c) transforming equations of motion including the real and imaginary parts of stiffness matrices (arising from the complex Young`s modulus) to undamped modal coordinate system, (d) decoupling of the modal equations of motion by transforming them into the damped modal coordinate system, and (e) computation of steady state response in the final coordinate system and transformation of the solution into the original structural coordinate system. This procedure is used to study the effects of structural damping (due to a viscoelastic layer of material present in the system) on dynamic the response due to periodic pulses of load acting on the grinding segments caused by grinding action.
