The invention relates to a five-dimensional vibration isolation device which is suitable for equipment arranged on a dynamic carrier. Aiming at the problem of five-dimensional vibration of the equipment on the dynamic carrier, one hybrid mechanism-based vibration isolation platform is arranged between an equipment mounting platform and a carrier connecting platform to realize five-dimensional vibration isolation. The vibration isolation platform consists of the equipment mounting platform (1), a middle platform (2), the carrier connecting platform (5), six branched chains comprising vibration isolation subsystems and a constraint branch containing no vibration isolation subsystem, so that vibration isolation along spatial three-movement two-rotation directions can be realized. Each vibration isolation subsystem in each branched chain is formed by connecting a linear spring (3) and a magneto-rheological damper (4) in parallel; and control over the entire platform is realized by changing a damping coefficient of the magneto-rheological damper. Since the movement and the rotation of a hybrid mechanism are fully decoupled, the control of the system is relatively simple. Experiments prove that the vibration isolation platform using the five-dimensional vibration isolation device enables that a vibration signal transferred to the equipment by the carrier is obviously weakened, so that the vibration isolation platform has the advantage of effectively and reliably improving the dynamic environment of the equipment of the dynamic carrier.
