ACOUSTIC MECHANICAL FEED-THROUGHS FOR PRODUCING WORK ACROSS A STRUCTURE

摘要

An apparatus that passes vibrational energy across a mechanical structure lacking a perforation. The disclosed apparatus and method provide the ability to transfer work (rotary or linear motion) across pressure or thermal barriers or in a sterile environment without generating contaminants; the presence of reflectors in the solid barrier to enhance the efficiency of the energy/power transmission, and the ability to produce a bi-directional driving mechanism using a plurality of different mode resonances, such as a fundamental frequency resonance and a higher frequency resonance. In some instances, a plane within the mechanical structure lacking a perforation is a nodal plane of the vibrational energy field.

主权项

1. An apparatus, comprising:
a mechanical structure having a first side and a second side opposite said first side, said mechanical structure lacking a perforation between said first side and said second side; a vibrational actuator situated on said first side of said mechanical structure, said vibrational actuator configured to provide vibrational energy; a work piece situated on said second side of said mechanical structure, said work piece configured to receive vibrational energy and to convert said vibrational energy into mechanical motion.
