Flexible piezoelectric fiber can be used on curved-surface structure, had broad application prospects in terms of novel intelligent material.
Another aspect inertia-type Piexoelectric actuator is because it is in impulse stroke, resolution ratio, working frequency, movement velocity, frequency
Rate response, manufacturing cost, by having unique advantage in terms of the stagnant ring draw degree of piezoelectric element, have been developed as pressure
One pith of electric precision actuation.Believed more than existing piezoelectric inertia drive device using Asymmetric Electric signal as excitation
Number, but this drive device has the shortcomings that signal is not easy to generation, mechanism and is not easily controlled, has the larger motion that retracts.In view of mesh
The problems of preceding piezoelectric inertia drive device, the present invention proposes a kind of asymmetric biplate piezoelectric fabric inertial drive dress
Put, the inertial impact force produced when being swung using top mass, Piexoelectric actuator is produced directed movement.Can with device
By property it is high, be easy to produce without electromagnetic interference, pumping signal and control, device controllability is good the advantages of.
