Description

W poblizu dna dolnego 3 znajduje sie ogranicznik ruchu 8.Ciezar urzadzenia drgajacego 5 jest równowazony parciem wywolanym róznica cisnien atmosferycznego i panujacego wewnatrz mieszka sprezystego 1. Role elementu nosnego spelnia powietrze atmosferyczne, a wiec zbiornik o obrzymiej pojemnosci i podatnosci. W przypadku znikomej sprezystosci mieszka 1 oraz wysokiej prózni w jego wnetrzu, polozenie zawieszonego na nim ciezaru byloby obojetne. W zwiazku z tym wszelkie " ruchy drgajace w pionie nie powodowalyby zadnych zmian sily w podlozu 4. Jednakze cala masa urzadzenia drgajacego 5 moglaby si niewielkie cisnienie w nim panujace sa korzystne, poniewaz spelniaja role stabilizatora polozenia srodka masy urzadzenia drgajacego 5. Do podloza 4przenosi sie sila pulsujaca pochodzaca od zmiany dlugosci mieszka sprezystego 1 oraz od zmiany objetosci zawartego w nim powietrza. Sila ta poprzez odpowiedni dobór podatnos¬ ci mieszka sprezystego 1 i cisnienia w nim, moze byc o trzy rzedy nizsza od ciezaru urzadzenia drgajacego 5. PL PLNear the bottom 3 there is a movement limiter 8. The weight of the oscillating device 5 is balanced by the pressure caused by the difference between the atmospheric pressure and the resilient bellows 1. The role of the supporting element is played by the atmospheric air, and thus the tank of high capacity and compliance. In the case of low elasticity of the bellows 1 and high vacuum inside it, the position of the weight suspended on it would be neutral. Therefore, any "vertical oscillation movements would not cause any changes in the force in the substrate 4. However, the entire mass of the vibrating device 5 could have a slight pressure in it, because it acts as a stabilizer for the center of mass of the vibrating device 5. It moves to the ground 4. The pulsating force resulting from the change in the length of the elastic bellows 1 and the change in the volume of air contained in it.This force, through appropriate selection of the flexibility of the elastic bellows 1 and the pressure in it, can be three orders lower than the weight of the vibrating device 5.
