Popis: In high-precision machines, e.g. wafer scanners or scanning electron microscopes, the achievable accuracy and repeatability is limited by (amongst others) the presence of poorly damped structural modes. These modes can be excited by floor/base vibrations and disturbances acting directly on the machine (e.g. cables, background noise or internal acceleration forces). Therefore, most precision machines are mounted on vibration isolation systems, which provide isolation from floor/base vibrations above the first resonance frequency, called the suspension mode frequency. This frequency is typically 1 Hz in these so called soft mounted machines. Unfortunately, in that case, the mount stiffness is small, which means the machine is very compliant to direct disturbances. The goal of this research project is to develop a vibration isolation system which offers efficient vibration isolation
