Design and Research of Integrated Active and Passive Vibration Isolation Device

The integrated active and passive isolation device has been studied according to the problems of the multi-excitation and the low-frequency vibration for the ship cabin equipment,which can provide the theoretical and engineering foundation for the development of the active control system based on the floating raft isolation design.Firstly,the electromagnetic actuator is preliminarily designed based on the principle of the electromagnetic actuation through the analysis and optimization design of the shape and clearance of the rotor and stator,the coil turns and the chamfer shape and size.It then carries out the simulation and analysis of the magnetic and heating characteristics based on the COMSOL modeling.Finally,the integrated active and passive vibration isolation device is designed and developed according to the requirements of the isolation,bearing and installation for the floating raft isolation device.The test results show that this device can meet the requirement of the output characteristics of the secondary force sources.
