Abstract
A mechanical isotropic harmonic oscillator including a two translational degrees of freedom linkage supporting an orbiting mass with respect to a fixed base with springs having isotropic and linear restoring force properties.
Claims20
A mechanical isotropic harmonic oscillator comprising:
- a fixed base;
- an intermediate block;
- a mass configured to oscillate;
- a first parallel spring stage connected between the mass and the intermediate block;
- and
- a second parallel spring stage connected between the intermediate block and the fixed base,
- wherein a direction of flexure of the first parallel stage is substantially perpendicular to a direction of flexure of the second parallel spring stage.
