A vibration isolation platform without angular displacement

Abstract

The invention relates to the technical field of vibration isolation buffering, in particular to a vibration isolation platform free of angular displacement. The vibration isolation platform comprisesa lower connecting plate, a metal rubber vibration isolator assembly, an anti-torsion assembly, an upper connecting plate and a transverse vibration isolation assembly; and the anti-torsion assembly is composed of a plurality of guide rail and sliding block combinations which are arranged in three spatially orthogonal directions and surround the outer side of the upper connecting plate. The anti-torsion component can restrain three torsion degrees of freedom, and meanwhile, the metal rubber vibration isolator assembly and the transverse vibration isolation assembly can isolate vibration in three directions horizontally and vertically, so that three-way vibration isolation free of the angular displacement of the vibration isolation platform is achieved.

technical field [0001] The invention relates to the technical field of vibration isolation and buffering, in particular to a vibration isolation platform without angular displacement. Background technique [0002] In order to improve the measurement and control accuracy of photoelectric instruments and equipment, and increase the reliability of their work, it is often necessary to install vibration isolation and vibration reduction devices between the instruments and equipment and the carrier platform.

However, during the use of the vibration damping device under the actual complex working conditions, angular displacement will inevitably occur

The harm of angular displacement disturbance to optoelectronic equipment is far greater than that of linear displacement disturbance, which greatly reduces the accuracy of optoelectronic equipment.

[0003] At present, most of the mainstream vibration isolators focus on the isolation of vertical vibration, and the lateral stiffness is insufficient. Parallel use may even amplify the disturbance of angular displacement.

The principle of the invented non-angular displacement vibration isolator is mostly realized by the parallelogram mechanism, the mechanism is complicated and the reliability is low

And when the mass of the vibration-isolated equipment is large, the parallelogram mechanism is prone to elastic deformation due to the weak components, so it is difficult to suppress the rigid body torsional mode of the vibration-isolated equipment
