摘要： 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 hydraulic pressure supply device, a torsion detection mechanism, and a controller. The torsion detection mechanism is constituted of displacement gauges such as a linear variable differential transformer. The displacement gauges are provided on hydraulic cylinders, and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders, respectively. The controller calculates a relative torsional angle between the first attachment member and the second attachment member based on the detected displacement.

摘要： 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.

摘要： 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.
