Structures under the influence of an external force are excited to resonance when the frequency of the external force and the natural frequency of the structure align with each other. Resonance leads to large deformation, which may cause damage to the integrity of the structure. There have been numerous applications of external devices that dampen the effects of excitation to the structure, such as tuned mass dampers, semi-active and active dampers, which have been implemented in buildings, bridges, and other large structures. One of the methods used for active cancellation uses the principle of centrifugal forces generated by the rotation of an imbalanced mass. These forces help counter the external excitation force applied to the structure. This research focuses on the working principle of active force cancellation using centrifugal forces due to mass imbalance and provides a virtual solution to simulate and predict the forces required to cancel the external excitation to an automotive structural system. This research addresses the challenges to miniaturize the CFG used for a Body on Frame truck and effectively reduce the amplitudes of the response due to a forcing function. The virtual tool presented in this thesis will help predict the maximum amplitude cancellation at resonance for given imbalance mass and frequency of forced excitation.
