【Abstract】 Aimed at the severe environment of vibration and shock,we suggest an active control technology against vibration and shock based on electromagnetic actuation and also develop a set of electromagnetic actuator. The numerical simulation and test result of the experimental sample indicate that the system can control both vibration and shock and it also has a wider frequency response range, a greater displacement response range and a satisfying vibration isolation ratio without resonance peak.更多还原
