These time histories correspond to damping ratios of 0, 0.1 and 0.5. (Recall that for oscillations to exist in the free reponse, the damping ratio must be less than one.) The most obvious influence of ...

This is demonstrated in the simulation results below. As seen is this simulation, a 5% damping ratio in the isolation system is a very effective design, whereas the larger damping produces ...

Furthermore, the press release continues that “the effective damping ratio was estimated to be between 37% and 75%, which is higher than many expensive passive damping systems.” The invention ...
