Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0043]The invention provides an active-passive hybrid vibration isolator for lateral impact resistance, comprising: a passive vibration isolator component, an active actuator component and a force transmission component;

[0044] The passive vibration isolator assembly includes: an upper mounting panel 1, a cover plate 4, a lower mounting panel 22, an airbag shock absorber capsule 15 and a locking device 27;

[0045] The locking device 27 is a bolt screw-in type or a toothed belt clamp type, which is used for height adjustment of the active and passive hybrid vibration isolator during installation, and is not installed in normal working conditions;

[0046] The airbag shock absorber capsule 15 is a single ball or annular airbag capsule or a cylindrical rubber body wrapped with a cord layer;

[0047] The upper mounting panel 1 is provided with a central th...

Abstract

The invention discloses an active-passive hybrid vibration isolator resistant to lateral impact, and belongs to the technical field of vibration noise control. The active-passive hybrid vibration isolator comprises a passive vibration isolator assembly, an active actuator assembly, and a force transmission assembly. The force transmission assembly is used to connect the passive vibration isolator assembly and the active actuator assembly and transmit force between the passive vibration isolator assembly and the active actuator assembly. The passive vibration isolator assembly supports static load of equipment, attenuates the force of lateral impact through the force transmission assembly, ensures normal work of the active actuator assembly, and has passive vibration isolation performance. The active actuator assembly produces radial output force when electrified, the output force is transmitted to the passive vibration isolator assembly through the force transmission assembly, and the output force is opposite to the exciting force of original radial impact, thus attenuating radial vibration. An active actuator of the vibration isolator is embedded into a passive shock absorber, so that the degree of integration is high. When an application object is subject to lateral impact, the active actuator can still work normally.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to an active and passive hybrid vibration isolator for resisting lateral impact. Background technique [0002] At present, ship vibration and noise reduction has received widespread attention and attention. Many vibration reduction measures have been taken to reduce the vibration and noise of equipment. The more commonly used vibration reduction measures are passive vibration reduction. Commonly used are single-layer vibration isolation and double-layer vibration isolation. , floating raft and cabin raft vibration isolation. With the further application of vibration reduction devices, the normally open power equipment and intermittently open equipment have achieved good vibration isolation effects due to the use of passive vibration reduction technology, but for ships that require extremely high stealth performance, only conventional passive control m...
