Problems solved by technology

[0006] But for the vertical vibration isolation system, reducing the stiffness will increase the static displacement and decrease the stability of the vibration isolation system; increasing the counterweight is obviously the last choice, and it is only used as a last resort, and the application is limited

Embodiment Construction

[0091] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0092] Such as Figure 1 to Figure 5 The structure of the present invention shown is a multi-dimensional vibration isolation platform with adjustable stiffness and damping, including a base frame A and a load-bearing platform B. The base frame A includes a base frame upper plate A-1 and a base frame lower plate arranged in parallel. The plate A-7, between the upper plate A-1 of the base frame and the lower plate A-7 of the base frame, is fixedly connected through a plurality of support columns A-8 of the base frame.

[0093] figure 1 with Figure 4 , the base frame A includes eight base frame support columns A-8; the eight base f...

Abstract

The invention discloses a multi-dimensional vibration isolation platform provided with multiple air springs and multiple dampers. The lower ends of the air springs and the lower ends of the dampers are connected with a base frame lower plate in a hinged mode through hinges. The upper ends of the air springs and the upper ends of the dampers are connected with a load disc through ball-shaped hinges. The load disc is connected with hydraulic cylinder piston rods of multiple hydraulic cylinders in a hinged mode through connecting rods. Cylinder bodies of the hydraulic cylinders are connected with a base frame upper plate in a hinged mode. The invention further discloses the air springs in the vibration isolation platform. By the adoption of the technical scheme, hydraulic pressure components serving as negative rigid components are in parallel connection with the air springs serving as positive rigid components, quasi-zero rigidity of the vibration isolation platform at a balance position and non-linear rigidity of the vibration isolation near the balance position are achieved, the difficulties caused when a traditional linear vibration isolation system isolates low-frequency vibration or ultra-low-frequency vibration can be solved, rigidity and damping can be adjusted simply and conveniently, and the multi-dimensional vibration isolation platform and the air springs are suitable for wide-frequency-domain vibration isolation and have good engineering applicability.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and relates to shock absorption and vibration isolation technology in mechanical engineering. More specifically, the present invention relates to a multi-dimensional vibration isolation platform. In addition, the invention also relates to the air spring with adjustable stiffness in the vibration isolation platform. Background technique [0002] In order to overcome the contradiction between system stiffness and static displacement, the vibration isolation system should have high static stiffness and low dynamic stiffness at the same time. Higher static stiffness ensures greater bearing capacity of the system and smaller static displacement; lower dynamic stiffness ensures lower natural frequency of the system and better low-frequency vibration isolation effect. [0003] In traditional passive vibration isolation systems, the external excitation frequency is greater than the natura...
