A separating dual-film spring-based intelligent flexible actuator comprises a flexible hinge (2), a strut (3), a slotting spring installation cover (4), an upper damping installation sheet (19) and alower damping installation sheet (20), wherein a voice coil motor (12) comprises a voice coil motor rotor (21) and a voice coil motor stator (22). After installation is completed, vibration isolation,vibration suppression and accurate directional adjustment of the intelligent flexible actuator are achieved by measurement feedback of a large-range and high-accuracy eddy current displacement sensor(17) and output control of the large-range and rapid-response voice coil motor (12). The intelligent flexible actuator employs a separating dual-film spring parallel structure form, is large in moving range and high in control accuracy, and can be widely applied to the field of ultrahigh-accuracy, ultrahigh-stability and super sensitive control of a spacecraft.
