A two-way no-angular-displacement damping device

Abstract

The invention belongs to the technical field of vibration reduction, and particularly discloses a two-way angle-displacement-free vibration reduction device. The two-way angle-displacement-free vibration reduction device comprises an angle-displacement-free mechanism, a base plate, a motion platform located above the base plate, and a plurality of sets of six-degree-of-freedom spring damping vibration reduction mechanisms; the angle-displacement-free mechanism comprises a floating frame located between the base plate and the motion platform and connected with the base plate through a pluralityof sets of double-ball-head joint connecting rod units to form a parallelogram mechanism in a three-dimensional space, thus the floating frame can make horizontal motion relative to the base plate and makes small-amplitude rotation movement in the axis direction of the floating frame, the floating frame is connected with the motion platform through a plurality of sets of vertical linear guide units, and thus it is ensured that the motion platform only makes vertical motion relative to the floating frame; and the multiple sets of six-degree-of-freedom spring damping vibration reduction mechanisms are arranged between the base plate and the motion platform and used for attenuating various-direction vibration transmitted from the base plate to the motion platform. The two-way angle-displacement-free vibration reduction device has the advantages of good damping effect, small vertical size and the like.

Description

Technical field [0001] The invention belongs to the technical field of vibration reduction, and more specifically, relates to a two-way non-angular displacement vibration reduction device. Background technique [0002] The vehicle-mounted and ship-borne optoelectronic platform is the installation and support platform for the optical components of the precision optical system, as well as the working platform of the optical system, which is the key to ensuring the high optical quality output of the precision optical system. However, the optoelectronic platform often faces mechanical environmental damage such as collisions, vibrations, and shocks in all directions of the surrounding environment during work, which may easily cause the optical path of the precision optical system to be misaligned or even damage the optical components; at the same time, if the optoelectronic platform is working, pitch vibration around the horizontal axis is generated. (Angular displacement) will cause ...

Problems solved by technology

However, the revolving pairs of this solution are all in the form of hinges, which limits the rotation of the adapter plate assembly around the vertical axis, causing the shock absorber to have no vibration damping effect in this direction. Therefore, when the carrier generates severe high-frequency torsional vibrations, only through The active control system inside the load cannot completely eliminate the vibration, which seriously affects the normal operation of the load
