Description

one

Isob, retiration refers to a special fidazdentam m under both equipment of high accuracy.

Vibrating and insulated foundations for high-precision equipment are known, including: a massive unit mounted with shock absorbers in an directly mounted outer box, i-meter, on a rpyHTOflOiM base.

Known designs are relatively complex. They have difficulty in accessing amortization elements, according to NWL there is a difficulty in obtaining the crI in yellow-springs of a massive block

low (, 5 Hz frequencies of its own oscillations.

The foundation of the proposed construction is devoid of these disadvantages.

In the proposed foundation design, in order to improve the vibro-insolation and conditions, the left side of the vibration-insulated object, as well as to achieve simplicity of construction, the outer base box is made closed, and the massive unit is suspended from the shock absorbers located on its upper part by means of rigid connections, on the side on the sides of the massive block, damping elements are mounted, connected to the outer corona: bom.

The drawing shows the proposed foundation.

The massive block 7 is suspended, for example, on pneumatic shock absorbers 2, placed on the upper part of the outer concrete box 3 by means of rigid connections 4 or 5. On the lateral sides of the massive block are mounted demutive elements 6 connected to the outer box 3.

The device can simultaneously be supplemented with 10 other types of mortizers of equal types, the prul I1na1: mi 7 ras enn.

The closed construction of the outer duct in the form of walls of high heat capacity, for example, concrete, a sufficiently large tire lid simultaneously contributes to the effective protection of the vibration-proof object from accidental influence of rapidly changing ambient temperatures.

The height of the suspension I is taken in accordance with the required low frequency of the natural oscillations of the block in the horizontal direction. This height can be approximately determined by the ratio

The adjustment in a certain range of frequency parameters of the block oscillations can be carried out by changing the operating parameters of the shock absorbers, demounting elements, for example, by changing the pressure in the pneumatic amortization (pax.
