Abstract
A mechanical isotropic harmonic oscillator including a frame, a mass configured to oscillate, and three flexure rods, each flexure rod connecting the mass to the frame.
Claims20
A mechanical isotropic harmonic oscillator comprising:
- a frame;
- a mass;
- and
- a plurality of flexure rods, the plurality of flexure rods consisting of:
- three co-planarly arranged flexure rods, each of the three flexure rods connecting the mass to the frame, wherein axes of longitudinal extension of the three flexure rods are oriented non-parallel with respect to each other, such that the mass is configured to perform a tilting oscillation motion about an axis that is perpendicular to a plane formed by the co-planarly arranged flexure rods, and
- a fourth flexure rod arranged transversally to the plane formed by the co-planarly arranged three flexure rods and attached to the mass.

An oscillator comprising:
- a frame;
- a mass configured to oscillate;
- a plurality of flexing means arranged in a first plane, the plurality of flexing means consisting of three flexing means, each one of the three flexing means connecting the mass to the frame and axes of longitudinal extension of the three flexing means oriented to be non-parallel with respect to each other to limit or block one rotational degree of freedom of the mass with respect to the frame, the three flexing means arranged such that the mass is configured to perform a tilting oscillation motion about an axis that traverses a center of gravity of the mass;
- and
- a fourth flexing means arranged transversally to the first plane and attached to the mass.
