Reduction of maximum amplitude magnification factors by numerical optimizations (μ=0.05). (Iterative solutions that take accounts of the primary system damping are displayed for several values of the primary system damping ratio [–]. The additional curves are provided only for comparison purposes, where the optimum parameter values for undamped primary system are diverted to the damped cases [[[dashed_line]]].)
