An issued NASA patent from the Technology Transfer catalog.
About this technology
Overview
Innovators at the Marshall Space Flight Center (MSFC) have developed a fluids-based tunable mass damper system that allows for significant distribution of loads while also providing a simple mechanism that allows for the capability to change its frequency of mitigation with negligible impact on the damper system. For existing fluid filled pipes, ducts, ballast tanks, etc., the fluid can now be leveraged to provide vibration mitigation. This new technology enables structural engineers to set and change the fundamental mitigation attributes of the mass damper system with little to no modification of the fluid container.
