Abstract: A damping device according to one embodiment includes a base member fixed to a vibration suppression target, a first coil spring, a second coil spring, and a weight member. The first coil spring includes a first fixed-side end turn portion supported on a first support portion of the base member, a first effective portion, and a first movable-side end turn portion. The second coil spring includes a second fixed-side end turn portion supported on a second support portion of the base member, a second effective portion, and a second movable-side end turn portion. Each of the first coil spring and the second coil spring is deflected in a longitudinal direction along the axis, and a transverse direction perpendicular to the axis. The weight member is arranged between the first coil spring and the second coil spring, and moves in the longitudinal direction and the transverse direction.

Abstract: A coil spring modeling apparatus includes a first attachment member disposed on a lower spring seat, a second attachment member disposed on an upper spring seat, an actuator unit formed of a Stewart-platform-type parallel mechanism, a spring height detection mechanism, and a controller. The spring height detection mechanism is constituted of displacement gauges such as a linear variable differential transformer. These gauges are provided on hydraulic cylinders, and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders, respectively. A hydraulic pressure supply device is controlled by the controller and supplies fluid pressure according to the displacement detected by the gauges to the respective hydraulic cylinders.

Abstract: A coil spring modeling apparatus includes an actuator unit formed of a Stewart-platform-type parallel mechanism, a first inner load cell accommodated in a first attachment member, a second inner load cell accommodated in a second attachment member, and a rotation support mechanism. The actuator unit is rotatably supported by the rotation support mechanism about an axis. The first inner load cell is arranged on the first seat adapter coaxially with the rotation support mechanism, and detects an axial force acting on the lower spring seat and a moment. The second inner load cell is arranged under the second seat adapter coaxially with the rotation support mechanism, and detects an axial force acting on the upper spring seat and a moment.
