A new surface mount system composed of parallel arrangement miniature manipulators was proposed by one of this paper authors. The miniature manipulator consists of a molded pantograph mechanism, which is composed of large deflective hinges and links, both made of the same materials, i.e., PP( Polypropylene). In the present study, the moment acting at the hinges in the molded pantograph mechanism is investigated dynamically by a theoretical analysis. In theory, the equation of moment at the hinge is shown by the sum of a restoring moment of elastic deformation and a viscous damping moment. In the experiments of the vibration between relative two links, a spring constant in the equation of restoring moment of elastic deformation and a viscous damping coefficient in the equation of viscous damping moment are obtained. By use of the dynamic theory including the equation of hinge moments, forces and moments acting at the hinges are analyzed. The obtained forces acting at the hinges are discussed, and compared with the forces acting at the pairs of the pantograph mechanism with revolute pairs. Furthermore, the dynamic output displacement of the pantograph mechanism is investigated experimentally comparing with the theoretical result.
