almost interchangeably with the <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/frequency-response-function\/\">frequency response function (FRF)<\/a> in vibration work \u2014 is a complex-valued function describing how a mechanical system responds to an input force or motion across frequency. Mathematically it is the ratio of output to input at each frequency, <em>H(f) = Output(f) \/ Input(f)<\/em>, carrying both magnitude information (how much the system amplifies or attenuates) and <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/phase\/\">phase<\/a> information (the time delay and resonance behaviour). Where a raw <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/spectrum\/\">vibration spectrum<\/a> tells you what a machine <em>is<\/em> doing, the transfer function tells you what it <em>would<\/em> do in response to any excitation.<\/p>\n<p>That distinction is what makes the transfer function so powerful. It characterises a structure&#8217;s inherent properties \u2014 its <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/natural-frequency\/\">natural frequencies<\/a>, <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/damping\/\">damping<\/a>, <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/stiffness\/\">stiffness<\/a>, and <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/mode-shape\/\">mode shapes<\/a> \u2014 independently of whatever forcing happens to be present during operation. This makes it the backbone of <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/modal-analysis\/\">modal analysis<\/a>, structural-modification prediction, <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/resonance\/\">resonance<\/a> diagnosis, and vibration-isolation design.<\/p>\n<h2>1. Mathematical Formulation<\/h2>\n<p>The basic definition is simply the ratio of two simultaneously measured spectra: <strong>H(f) = Y(f) \/ X(f)<\/strong>, where Y(f) is the output (response) spectrum and X(f) the input (excitation) spectrum.<\/p>\n<h3>The Cross-Spectrum Estimator<\/h3>\n<p>In the real world both signals contain noise, so a naive division amplifies error. The standard practical estimator instead uses spectral averages: <strong>H(f) = G<sub>xy<\/sub>(f) \/ G<sub>xx<\/sub>(f)<\/strong>, where G<sub>xy<\/sub> is the <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/cross-spectrum\/\">cross-spectrum<\/a> between input and output and G<sub>xx<\/sub> is the <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/auto-spectrum\/\">auto-spectrum<\/a> of the input. Because uncorrelated noise on the output averages toward zero in the cross-spectrum, this form (the &#8220;H1&#8221; estimator) suppresses bias from output noise and is the method used in practice.<\/p>\n<h3>The Four Components<\/h3>\n<p>Being complex-valued, a transfer function can be viewed four ways, each emphasising something different:<\/p>\n<ul>\n<li><strong>Magnitude |H(f)|:<\/strong> the amplification factor at each frequency.<\/li>\n<li><strong>Phase \u2220H(f):<\/strong> the phase lag of the output relative to the input.<\/li>\n<li><strong>Real part:<\/strong> the in-phase component of the response.<\/li>\n<li><strong>Imaginary part:<\/strong> the quadrature (90\u00b0) component, whose peaks neatly mark resonances.<\/li>\n<\/ul>\n<h2>2. Physical Meaning \u2014 Reading Magnitude and Phase<\/h2>\n<h3>What the Magnitude Tells You<\/h3>\n<ul>\n<li><strong>|H| &gt; 1:<\/strong> the system amplifies at this frequency \u2014 the resonance region.<\/li>\n<li><strong>|H| = 1:<\/strong> output equals input, a neutral response.<\/li>\n<li><strong>|H| &lt; 1:<\/strong> the system attenuates, as in effective isolation or operation well off resonance.<\/li>\n<li><strong>Peaks<\/strong> occur at natural frequencies, and their <strong>height<\/strong> is governed by damping \u2014 the taller and sharper the peak, the lower the damping.<\/li>\n<\/ul>\n<h3>What the Phase Tells You<\/h3>\n<p>Phase is the more reliable resonance indicator, because it behaves the same regardless of how the plot is scaled:<\/p>\n<ul>\n<li><strong>0\u00b0:<\/strong> output in phase with input \u2014 stiffness-controlled region, below resonance.<\/li>\n<li><strong>90\u00b0:<\/strong> output lags by a quarter cycle \u2014 precisely at resonance.<\/li>\n<li><strong>180\u00b0:<\/strong> output exactly opposed to input \u2014 mass-controlled region, above resonance.<\/li>\n<\/ul>\n<p>The hallmark of a genuine resonance is this characteristic 180\u00b0 phase shift as frequency sweeps from below the peak to above it; a magnitude bump without the accompanying phase rollover is usually something else.<\/p>\n<h2>3. How the Transfer Function Is Measured<\/h2>\n<h3>Impact Testing (Bump Test)<\/h3>\n<p>The most common approach on installed machinery is the <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/bump-test\/\">bump test<\/a>: strike the structure with an instrumented hammer (which measures the input force) while an <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/accelerometer\/\">accelerometer<\/a> records the response. It is quick and needs no equipment beyond the hammer and sensor, though a single impact offers limited averaging and the usable force spectrum is shaped by the hammer tip.<\/p>\n<h3>Shaker Testing<\/h3>\n<p>A controlled electromagnetic shaker drives the structure with random, swept-sine, or chirp excitation, giving excellent control over both force level and spectral content. It is the gold standard for <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/impact-testing\/\">modal testing<\/a> accuracy, at the cost of needing dedicated shaker hardware.<\/p>\n<h3>Operational Measurement<\/h3>\n<p>Here the running machine&#8217;s own forces serve as the input, capturing genuine operating conditions but sacrificing control \u2014 the challenge becomes identifying or measuring that input, whether through a force gauge or a suitable reference point.<\/p>\n<h2>4. Where Transfer Functions Are Used<\/h2>\n<ul>\n<li><strong>Modal analysis:<\/strong> magnitude peaks locate natural frequencies, the phase rollover confirms each is a true resonance, peak width quantifies damping, and combining measurements from many points reconstructs the mode shapes.<\/li>\n<li><strong>Resonance diagnosis:<\/strong> comparing operating frequency to the measured natural frequencies establishes the separation margin and flags problematic resonances, guiding any modification strategy.<\/li>\n<li><strong>Vibration isolation design:<\/strong> the transfer function directly shows transmission versus frequency. The isolator&#8217;s own natural frequency appears as a peak, and above roughly 1.4\u00d7 that frequency the response drops below unity, with good isolation typically beyond 2\u00d7.<\/li>\n<li><strong>Structural modification prediction:<\/strong> the measured function lets engineers predict the effect of adding mass, stiffness, or damping, then validate the change with a before-and-after comparison.<\/li>\n<\/ul>\n<h2>5. Interpretation in a Machinery Context<\/h2>\n<h3>The Rotor-Bearing System<\/h3>\n<p>Treating <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/unbalance\/\">unbalance<\/a> force as the input and bearing vibration as the output, the transfer function reveals exactly how unbalance is converted into measurable vibration. Its peaks sit at the machine&#8217;s <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/critical-speed\/\">critical speeds<\/a>, which is why the concept is central to <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/rotor-dynamics\/\">rotor dynamics<\/a> analysis and to understanding why a rotor responds violently at some speeds and quietly at others.<\/p>\n<h3>Foundation and Transmission Paths<\/h3>\n<p>With bearing-housing vibration as the input and floor or <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/foundation-stiffness\/\">foundation<\/a> motion as the output, the transfer function maps the transmission path, exposing the frequencies at which energy passes most readily into the structure and guiding decisions about isolation or stiffening.<\/p>\n<h3>Where field instruments fit<\/h3>\n<p>This thinking shapes everyday field work even when no formal FRF is computed. In <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/field-balancing\/\">field balancing<\/a>, a portable two-channel analyser such as the <a href=\"https:\/\/vibromera.eu\/uz\/mahsulot\/balanset-1\/\">Balanset-1A<\/a> measures the rotor&#8217;s 1\u00d7 amplitude-and-phase response to a known <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/trial-weight\/\">trial weight<\/a> and effectively builds a single-frequency transfer function \u2014 the <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/influence-coefficient\/\">ta&#039;sir koeffitsienti<\/a> \u2014 that tells the software precisely how the rotor reacts to mass at each plane, and therefore how to correct it.<\/p>\n<h3>Validating Quality with Coherence<\/h3>\n<p>A transfer function is only trustworthy if input and output are genuinely related, and <a href=\"https:\/\/vibromera.eu\/uz\/glossary\/coherence\/\">coherence<\/a> is the metric that confirms it. Coherence above about 0.9 indicates a reliable function; low coherence warns of a poor measurement or uncorrelated noise \u2014 so it should always be checked before any transfer function is relied upon.<\/p>\n<p>The transfer function is among the most powerful analytical tools in machinery dynamics, distilling the fundamental input\u2013output relationship of a structure into a single complex function. Mastering its measurement, its interpretation \u2014 especially recognising resonances from magnitude peaks and their telltale phase transitions \u2014 and its applications unlocks modal analysis, resonance diagnosis, structural-modification prediction, and the transmission analysis that underpins advanced vibration control.<\/p>\n<hr>\n<p><a href=\"https:\/\/vibromera.eu\/uz\/glossary\/\">\u2190 Back to Main Index<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Learn about transfer function (frequency response function), ratio of output to input showing how systems respond to vibration, essential for modal analysis and structural dynamics.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"ai_generated_summary":"","footnotes":""},"categories":[109,110],"tags":[],"class_list":["post-278","glossary","type-glossary","status-publish","hentry","category-glossary","category-vibration-diagnostics"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/glossary\/278","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/glossary\/278\/revisions"}],"predecessor-version":[{"id":101317,"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/glossary\/278\/revisions\/101317"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/media?parent=278"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/categories?post=278"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/uz\/wp-json\/wp\/v2\/tags?post=278"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
