VIBRATION GENERATION DEVICE, DYNAMIC VISCOELASTICITY MEASURING DEVICE, AND DYNAMIC VISCOELASTICITY MEASURING METHOD

PROBLEM TO BE SOLVED: To provide a vibration generation device and a dynamic viscoelasticity measuring device for dynamic viscoelasticity measurement capable of realizing miniaturization, weight reduction and cost reduction by simplifying the whole device, and to provide a dynamic viscoelasticity measuring method. SOLUTION: This vibration generation device for generating rotational vibration for measuring a dynamic viscoelasticity is equipped with an actuator for performing linear operation by a driving force in the linear direction; a displacement enlarging mechanism for amplifying displacement of the linear operation by the actuator by utilizing the principle of leverage by arranging a point of effort on the actuator side; and a rotational operation conversion mechanism for converting displacement into rotational operation, and generating rotational vibration to an object for measuring the dynamic viscoelasticity, by being constituted so as to transmit the amplified displacement to a tangential direction of a circular section of a rotating shaft.
