Vibration isolation control in precision equipment
Engineering Education # 09, September 2012 DOI: 10.7463/0912.0454475 The article presents assessment of damping properties of magnetorheological (MR) elastomers under their exposure to a magnetic field. The authors study the efficiency of vibration energy absorption by MR elastomers with the use of the obtained dependences of mechanical hysteresis. The results of experimental studies of the active damper are based on the MR elastomer.
# 07, July 2012 In this paper we consider the possibility of using active vibration control system based on magnetorheological elastomer dampers for nanotechnological equipment.High-frequency oscillations, in the manufacture of microelectronic components, the frequency of successfully isolated using passive systems of vibration protection. Much more dangerous are the fluctuations with low frequencies, and are addressed by using active vibration control system based on the MR elastomers.
Research of properties of magnetorheological fluids and their use in movement and vibroinsulation devices
Engineering Education # 09, September 2012 DOI: 10.7463/0912.0434696 In order to move objects with submicron accuracy and vibration control of equipment, in modern precision equipment precision positioning mechanisms based on magnetorheological fluids (MRF) can be successfully applied. It is shown that the work of these mechanisms have a significant impact on the properties of the fluid and, in particular, on electrical resistance and the bulk modulus of elasticity. It was found that with application of an external field to MRF electrical resistance decreases by 30% and the bulk modulus increases by 18%.
