Active vibration isolation

The Hummingbird technology was developed by MECAL and TNO in response to the growing need for highly effective, robust and affordable vibration reduction systems. It combines new and existing technologies to significantly reduce floor vibrations and also suppress disturbances caused by machine movement, ranging from very low to high frequencies. This article discusses the basics and common concepts – with their possibilities and limitations – for (active) vibration isolation. The underlying technologies provide the context for a concise description of the Hummingbird.
