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.
