Two effects of investing semi-circular curved linear-motor device for absorbing vibration of single-degree-of-freedom structure subjected to earthquake groud motion with arbitrary distributed artificial gravity are described. The one is to be able to adjust natural period of pendulum motion of auxiliary mass, that provides passive force by sliding oneself on semi-circular curved rail in the device, without remaking curvature of the rail. The other is to be able to suppress reckless motion of the auxiliary mass without significant loss of efficiency of vibration control when violent ground motion attacking. These effects are verified by computer simulations and shaking table tests on a single story steel structured model with the device subjected to artificial earthquake ground motion.
