Abstract

Operation of sensitive equipment aboard multi-sensor platforms requires active vibration isolation technology. In response to these needs, the active isolation fitting (AIF) was developed to replace passive mechanical end fittings and joints in truss structures. The AIF combines intrastructural and inertial devices to cancel vibration transmission into a vibration-sensitive subsystem. This paper discusses the AIF principles of operation, details its robust performance characteristics and reviews the extensive experimental results that have been accumulated over the past several years. Test results show 20 to 30 dB of broadband isolation for both single AIF tests and six degree-of-freedom isolation systems demonstrated on two major, government- supplied testbeds.
