摘要
The present invention relates to a method and apparatus for isolating vibration from a supported payload, and more particularly to an active vibration separation system using sensors and reinforcement actuators. The active vibration isolation system 10 includes a plurality of reinforcement actuators 12a, 12b, 12c; 284; 350 that support the small objects 18 inside the case 300. The passive separator 20 is installed between the small object 18 and the payload mass M p . If the reinforcing actuator is a piezoelectric motor, the sidewall of the case 300 is used to apply a compressive force along the variable length of each of the horizontal piezoelectric motors to prevent damage to them. Between the speed sensor 17 and the reinforcement actuator, a gain module 24 for controlling the variable length of the reinforcement actuator in the move-out-of-the-way system 10 to compensate for the resonance mode is connected. It is also possible to use payload mass velocity sensor 26 and associated circuitry for further control. Shear decouplers 282a, 282b, 282c, 352 and 360 are used in conjunction with piezoelectric motors to minimize shear forces on the motor.
