Resonance engine

摘要

A resonance engine is disclosed including: a driver plate, to which is coupled at least one oscillatory transducer; a drive signal generator connected to the oscillatory transducer for excitation thereof; a first spring-mass resonator, having a first natural resonant frequency, with a proximal end attached to the driver plate and a free distal end; and a reaction means attached to the driver plate substantially opposite to the first spring-mass resonator. When the oscillatory transducer is excited by a drive signal from the generator having a component at or close to said natural resonant frequency, the first spring-mass resonator oscillates at resonance, substantially in anti-phase to the driver plate. Small vibrational strains in the oscillatory transducer are converted to large strains of controllable kinematic movements.

1. A resonance engine, comprising:
a driver plate, to which is coupled at least one oscillatory transducer; a drive signal generator for generating an electrical signal, the drive signal generator being connected to the oscillatory transducer for excitation thereof; a first spring-mass resonator, having a first natural resonant frequency, including a first spring with a proximal end attached to the driver plate and a free distal end, and a discrete mass attached at or near the free distal end of the first spring; and a reaction means attached to the driver plate opposite to the first spring-mass resonator; wherein the reaction means comprises a second spring-mass resonator mounted symmetrically to the first spring-mass resonator on the driver plate, the second spring-mass resonator including a second spring with a proximal end attached to the driver plate and a free distal end, and a discrete mass attached at or near the free distal end of the second spring; wherein when the oscillatory transducer is excited by a drive signal from the drive signal generator having a component at said first natural resonant frequency, the first spring-mass resonator oscillates at resonance, in anti-phase to the driver plate; and wherein the spring-mass resonators are so tuned and arranged that torque force moments generated by the respective spring-mass resonators cancel each other out and cancel out torque force moments of the driver plate, thereby resulting in a system in which substantially all energy input to the driver plate is transmitted to the spring-mass resonators for deflection of the free distal ends thereof.
