Based on the analyzing of vibration transmissibility of passive vibration isolation system and active vibration isolation system, the vibration transmissibility of the vibration isolation system under complex vibration environment with the floor disturbance and the direct disturbance is defined. The calculating formulas for the vibration transmissibility of passive vibration isolation system and active vibration isolation system with complex vibration environment are established. The influencing relationships between the vibration transmissibility of the vibration isolation system and the feedback parameters such as acceleration, velocity and displacement are studied systematically.
