The invention discloses an active and passive integrated vibration isolation device and a vibration isolation platform. The vibration isolation device comprises an elastic plane net structure, an active electromagnetic dynamic vibration absorber, and a piezoelectric stack actuator. The elastic plane net structure is formed by weaving steel wires in a tensioning and crossed manner. The active electromagnetic dynamic vibration absorber is arranged on the intersection of a central region of the elastic plane net structure. The piezoelectric stack actuator is arranged on the edge position of the elastic plane net structure. The vibration isolation platform comprises the vibration isolation device, a bearing cylinder, an intermediate support, and a control system. A satellite attitude control device assembly is arranged on the intermediate support. The intermediate support is installed on the vibration isolation device. The vibration isolation device is installed on the inner side of the bearing cylinder. The control system is used to control the active electromagnetic dynamic vibration absorber according to vibration acceleration information of the intermediate support, and control the piezoelectric stack actuator according to the vibration acceleration information of the bearing cylinder. The vibration isolation device and the vibration isolation platform are effective for low-frequency line spectrum, and have good control effect on broadband random excitation.
