Abstract

Kits and methods for building devices for analyzing or suppressing vibrations in equipment are provided. An electrical-mechanical transducer is configured to be placed in operative contact with the equipment. The transducer may be directly mounted to a base plate that is configured for being mounted to the equipment. A first device (e.g., a printed circuit board) carrying electronic componentry is configured for transmitting vibration drive signals to the electrical-mechanical transducer. A second device (e.g., a printed circuit board) carrying electronic componentry is configured for receiving vibration sensing signals from the electrical-mechanical transducer. The first and second devices can be interchangeably mounted within a housing that can be mounted to the base plate. The housing may comprise an aperture for receiving the electrical-mechanical transducer.

Claims

1. A method of implementing a vibration suppression system on equipment, comprising:

mounting an electrical-mechanical transducer to the equipment;

connecting first electronic componentry to the electrical-mechanical transducer;

transmitting vibration sensing signals from the electrical-mechanical transducer to the first electronic componentry in response to vibrations in the equipment;

removing the first electronic componentry from the electrical-mechanical transducer;

connecting second electronic componentry to the electrical-mechanical transducer; and

transmitting electrical drive signals from the second electronic componentry to the electrical-mechanical transducer to induce vibrations at the equipment.

2. The method of claim 1, wherein the electrical-mechanical transducer is a piezoelectric element.

3. The method of claim 1, wherein the first and second electronic componentry are carried by printed circuit boards.

4. The method of claim 1, further comprising analyzing the vibration sensing signals, and modifying the second electronic componentry based on the analysis.

5. The method of claim 4, wherein the second electronic componentry is modified by programming it with a vibration suppression control algorithm.
