paglaban ng buong suporta ng isang makina &mdash; baseplate, grout, concrete block, pedestals, at ang lupa sa ilalim &mdash; sa pagdeflect sa ilalim ng static at dynamic forces na ipinapahit ng rotating machine. Ito ay dinikilala bilang force per unit deflection (N\/mm, N\/m, o lbf\/in) at sinasagot ang isang nakabuluhang simpleng tanong: gaano kalayo ang paggalaw ng foundation kapag itinulak ng makina? Ang iisang numero na iyon ay kumakalat sa buong makina, dahil ang foundation stiffness ay isa sa mga komponente ng <a href=\"https:\/\/vibromera.eu\/tl\/glossary\/stiffness\/\">stiffness<\/a> chain na, kasama ang rotor at bearing stiffness, nangongotrol sa <a href=\"https:\/\/vibromera.eu\/tl\/glossary\/rotor-dynamics\/\">rotor dynamic<\/a> behaviour.

Kahulugan at Bakit Ito Mahalaga<\/h2>\n<p>Ang isang foundation ay bihira ang maging matibay, hindi gumagalaw na angkla tulad ng iniisip nito. Ito ay nagdedeflect, at ang mas matibay ito, mas kaunti itong nagdedeflect para sa isang naibigay na force. Dahil ang rotor, ang mga bearings nito, at ang foundation ay gumagalaw na parang springs na kumilos sa series, ang foundation ay maaaring maging ang mahihinang link na nangingibabaw sa pinagsama-samang tugon &mdash; at ang natitira ng artikulong ito ay sumusunod kung paano eksaktong.<\/p>\n<h3>Epekto sa mga kritikal na bilis<\/h3>\n<p>Ang foundation stiffness ay direktang nagpapakain sa <a href=\"https:\/\/vibromera.eu\/tl\/glossary\/natural-frequency\/\">natural frequencies<\/a>:<\/p>\n<ul>\n<li>Ang kabuuang stiffness ng system ay ang series combination ng rotor, bearing, at foundation stiffnesses, kaya ang pinakamahina at elemento ay may pinakamalaking sinasabi.<\/li>\n<li>Ang isang soft foundation ay nagbababa ng kabuuan, na nagbababa ng mga critical speeds.<\/li>\n<li>Iyon ay maaaring humigit sa isang critical speed pababa sa isang ligtas na margin at sa operating range.<\/li>\n<li>Dahil ang critical speed ay umakyat sa \u221a(total stiffness), kahit isang maliit na pagkawala ng foundation stiffness ay may tunay na epekto &mdash; maaari kang magsukat ng shift sa isang <a href=\"https:\/\/vibromera.eu\/tl\/calculators\/rotor-critical-speed\/\">Rotor Critical Speed Calculator<\/a>.<\/li>\n<\/ul>\n<h3>Kontrol ng amplitude ng vibrasyon<\/h3>\n<ul>\n<li><strong>At resonance:<\/strong> ang mas matatag na pundasyon ay karaniwang nakakalikha ng mas mababang tuktok na vibrasyon na amplitude.<\/li>\n<li><strong>Ibaba ng resonance:<\/strong> isang napakalakas na foundation ay maaaring <em>increase<\/em> ipinagdating na vibrasyon, dahil hindi ito nagbibigay ng isolasyon.<\/li>\n<li><strong>Pinakamahusay na disenyo:<\/strong> ang tamang sagot ay binabalanse ang stiffness laban sa isolation para sa partikular na frequency range ng makina.<\/li>\n<\/ul>\n<h3>Katatagan ng pagkakahanay<\/h3>\n<ul>\n<li>Ang isang flexible na pundasyon ay nagpapahintulot sa kagamitan na lumipat sa ilalim ng pag-operate na mga load.<\/li>\n<li>Ang thermal growth ng makina ay maaaring gawing baluktot ang isang yielding foundation.<\/li>\n<li>Precision <a href=\"https:\/\/vibromera.eu\/tl\/glossary\/laser-shaft-alignment\/\">laser shaft alignment<\/a> ay mahirap hawakan sa isang soft base.<\/li>\n<li>Ang foundation deflection mula sa external process loads, tulad ng piping forces, ay tahimik na nagbababa ng alignment &mdash; at isang nakatagong <a href=\"https:\/\/vibromera.eu\/tl\/glossary\/soft-foot\/\">soft foot<\/a> ay maaaring tulad o makabagong problema.<\/li>\n<\/ul>\n<h2>2.
