We use two design concepts of minimizing resonance amplitude and minimizing standard deviation of amplitude against external disturbance random vibrations of foundation. To minimize resonance amplitude, the damping ratio, which corresponds to the restriction coefficient of viscous restriction, has to be chosen in order to equalize the resonance amplitude under the condition of parallel oscillating to that under the condition of rotating oscillating. To minimize standard deviation of amplitude of the system, the optimum damping ratio which minimize the standard deviation of amplitude of the system under the condition of rotating oscillating has to be chosen when the natural frequency of the parallel mode is lower than that of the rotating mode. The optimum damping ratio which minimize the standard deviation of amplitude of the system under the condition of parallel oscillating has to be chosen when the natural frequency of the rotating mode is lower than that of the parallel mode.c
