The invention discloses an eight-rod-redundant-configuration and six-degree-of-freedom active vibration control device, which comprises an upper platform, a lower platform and eight active vibration isolating mechanisms, wherein the upper platform and the lower platform are arranged horizontally, and are connected with each other through the eight active vibration isolating mechanisms; and each active vibration isolating mechanism comprises an upper platform flexible hinge, a dynamic force sensor, voice coil motor actuators and a lower platform flexible hinge. An eight-rod-redundant-configuration active vibration control platform with the structure has a six-degree-of-freedom moving capability and can be used for performing omnibearing vibration isolation and suppression. The eight-rod-redundant-configuration and six-degree-of-freedom active vibration control device has the advantages that: eight voice coil motor actuators stretch, so that the upper platform can realize three-degree-of-freedom translation and three-degree-of-freedom rotation, a silent working environment is created for the upper platform, and the accuracies of optical equipment and laser equipment on the upper platform are greatly enhanced; and moreover, the eight-rod-redundant-configuration and six-degree-of-freedom active vibration control device has a high response speed, high accuracy and high reliability.
