Abstract

The invention discloses a double-intelligent flexible beam device based on the driving and oscillating of a planetary reducer. The device comprises a flexible beam body part, an oscillation detection part and a drive control part; the flexible beam body part comprises double-flexible amount, one end of the double-flexible beam is a free end, and the other end is a fixed end; the fixing end of the double-flexible beam is fixed on an output shaft of the planetary reducer so that the planetary reducer can rotate in a horizontal plane; a piezoelectric sensor and a piezoelectric actuator are glued nearby the fixing end of the double-flexible beam, and a computer outputs a control signal to a servo motor and a piezoelectric actuator to be used for the rotary control in the horizontal plane of the double-flexible beam after the computer receives a vibration signal of the piezoelectric sensor.

Description

technical field [0001] The invention relates to the field of positioning and vibration control of large-scale rotating flexible structures, in particular to a swinging double intelligent flexible beam device driven by a planetary reducer. Background technique [0002] Compared with other transmission and control methods, servo motor drive technology has the following advantages: high control precision, wide speed range, good dynamic characteristics, easy operation, easy programming, and positioning servo; fast response, easy to connect with CPU, Small size, large power, and no pollution; compared with pneumatic drive, servo motor drive technology can greatly improve the accuracy of transmission and control, the motor is small in size, stable in action, more suitable for long-distance transmission, and has less working noise; Compared with the drive, the hydraulic drive is difficult to miniaturize, the hydraulic source or hydraulic oil has strict requirements (impurities, tem...
