US 2025/0367705 A1 · COMPLEX MODULATED HIGH FREQUENCY/LOW FREQUENCY VIBRATION TOOL

Abstract

The invention provides a novel vibration generation tool that utilizes a complex modulated high frequency actuator to create modulated low frequency hammer vibrations or compounded complex modulated high frequency and corresponding complex modulated low frequency hammer vibrations applied to a structure. Novel application of complex modulated actuator driving signals are used to stimulate wideband frequency response vibrations from a structure under treatment to facilitate improved cleaning, stress relief, screen de-blinding, and process improvement for a wide range of applications where wideband frequency vibrations may be helpful. It is especially helpful in applications where scale or fouling tends to accumulate and requires periodic or full-time remediation. The modulated high frequency/low frequency vibration tool may be used as a handheld portable tool, mounted to a robotic system, or fixed to a structure for long-term or periodic operation.

Dependent claims

A vibration generation apparatus comprising:

a control system configured to generate a configurable complex sonic high-frequency driving signals;
an actuator comprising:
an actuator end tip at a first axial end of the actuator;
and
a connection to the control system, the actuator adapted to generate complex modulated sonic high-frequency vibrations at a predetermined frequency and amplitude when receiving complex high-frequency driving signals;
a waveguide rigidly coupled to an actuator end tip;
and
a striker mass disposed between said actuator first axial end and said waveguide, the striker mass configured to engage the actuator end tip thereby converting the complex modulated sonic high-frequency vibrations into corresponding modulated complex lower frequency hammering impacts transmitted to the waveguide, and wherein the waveguide is configured to transmit to its distal end the combined vibrations comprising the complex modulated sonic high-frequency vibrations generated by said actuator and the corresponding modulated complex lower frequency hammering impacts produced by said free striker mass.
