Embodiment Construction

[0016] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0017] Such as figure 1 A tensioned integral vibration isolation mechanism shown includes a working platform 1, a fixed platform 8, four rigid-flexible mixed branch chains and four flexible branch chains located between the two platforms.

[0018] The rigid-flexible hybrid branch chain is composed of a hydraulic driver and a small spring 3 in series, and the upper end of the piston rod 5 of the hydraulic driver and the lower end of the small spring 3 are connected by welding. The upper end part of the spring 3 is fixedly connected with the working platform 1 through a spherical hinge-2. The lower end of the cylinder 6 of the hydraulic driver and the fixed platform 8 are fixedly connected by the two spherical hinges 9. The springs in...

Abstract

The invention relates to a tension overall vibration isolation mechanism. The tension overall vibration isolation mechanism comprises a working platform, a fixed platform, four rigid-flexible mixed branch chains connected between the working platform and the fixed platform, and four flexible branch chains; the rigid-flexible mixed branch chains consist of rigid element hydraulic drives and flexible element springs, wherein the upper parts of piston rods of the hydraulic drives and the springs are serially connected to the working platform; and the flexible branch chains are formed by serially connecting springs positioned at the upper half parts with ropes at the lower half parts. The tension overall vibration isolation mechanism has the following beneficial effects: compared with a traditional vibration isolator, the tension overall vibration isolation mechanism can realize the vibration reduction of space in any six directions, and has such advantages as low mass, folding capacity, low motion component inertia and wide application range.

Description

Technical field [0001] The present invention relates to the field of vibration reduction, in particular to a vibration isolation and reduction device applied to precision instrument platform vibration isolation and reduction or various micro-vibration isolation and vibration reduction environments. Background technique [0002] In recent years, with the rapid development of science and technology and the continuous improvement of modernization, in the fields of aerospace, precision instrumentation, national defense technology, etc., for vibration and noise reduction, safety and comfort, fatigue resistance, and improved service life and information accuracy The requirements are getting higher and higher. The anisotropy of general vibration damping devices can only meet the requirements of one-way vibration damping of precision instruments, such as adding vibration isolation sponge, vibration isolation foam, vibration isolation air cushion or vibration isolation spring. This metho...
