The dynamic characteristic of a gear transmission system is an important parameter to define its quality. The variation in the number of teeth in contact during rotation of the gears has a large contribution to the vibrations of these systems. From this context, the need to evaluate the dynamic characteristics of the gear while it is still in the design phase is highlighted. In this work, the influence of addendum modification to the tooth profile of spur gears on the gear mesh vibration was studied. For this purpose, simulations were performed in order to determine an optimal value to the modification parameter capable of minimizing the vibrations. The model of the dynamic system used in this problem considers time-varying meshing stiffness and damping, and it includes an improvement to the equivalent mass calculation compared to other works in the field. It is shown that the amount of modification obtained for specified operating conditions presents optimal results only for those designed conditions, and its behavior degrades significantly if operating conditions change. From the comparison between the simulation results of the optimized and original system, it is concluded that the optimal modification brings the dynamic responses closer to the static ones, with change rates close to zero and nearly constant transmission error, providing minimal vibration to the system.
