Description

technical field [0001] The invention relates to the technical field of vibration control of mechanical equipment, in particular to an electromagnetic active-passive integrated vibration isolator integrating an electromagnetic actuator and a passive vibration isolator. Background technique [0002] The vibration of mechanical equipment will not only affect the working performance of the equipment itself, but also generate noise pollution, seriously affecting the hearing and health of people around the equipment. In addition, for military ships, the vibration of their power equipment will produce hull radiation noise, which greatly affects the acoustic stealth of the ship and increases the possibility of being discovered and attacked by the enemy. Therefore, it is of great significance to effectively control the vibration of mechanical equipment. [0003] At present, the vibration control technology of mechanical equipment can be divided into passive type and active type acco...

Problems solved by technology

[0005] The purpose of the present invention is to solve the following problems in the existing vibration reduction and isolation components: passive vibration isolators have poor low-frequency vibration isolation effect; passive dynamic vibration absorbers are difficult to achieve broadband vibration control and have poor robustness; active dynamic vibration absorbers In the application of large-scale equipment vibration control, the space utilization rate is not high; the series active-passive integrated vibration isolator occupies a large space in the height direction; the existing parallel active-passive integrated vibration isolator, the electromagnetic actuator is located in the passive Inside the vibration isolator, the output force of the actuator is limited; an electromagnetic active-passive integrated vibration isolator is provided. The invention places the electromagnetic actuator on the outside of the passive vibration isolator to perform parallel active-passive integration Vibration isolation, since the electromagnetic actuator is located outside the passive vibration isolator, its size and magnetic pole area can be designed larger, so that it can output greater electromagnetic force
