measurement and evaluation of <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/vibration\/\">vibration<\/a> <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/amplitude\/\">amplitude<\/a> and <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/phase\/\">phase<\/a> while a machine accelerates from rest or low speed up to its operating speed. By recording data continuously throughout <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/runup\/\">startup<\/a>, an analyst can locate every <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/critical-speed\/\">critical speed<\/a> the rotor passes through (each appears as an amplitude peak), gauge how much <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/damping\/\">damping<\/a> the system has (from the sharpness of those peaks), expose startup-specific faults such as <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/thermal-bow\/\">thermal bow<\/a>, and confirm that the startup procedure itself is sound. The results are normally presented as <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/bode-plot\/\">Bode plots<\/a> \u2014 amplitude and phase against speed \u2014 and <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/waterfall-plot\/\">waterfall plots<\/a> that show how the whole spectrum evolves as the machine speeds up.<\/p>\n<p>The technique is indispensable in three settings: commissioning new equipment, where it verifies that the real machine behaves as the rotor-dynamic design predicted; troubleshooting, where it reveals whether a startup vibration problem is resonance-driven; and periodic health assessment, where today&#8217;s run-up signature is compared against a historical baseline to catch slow degradation before it becomes a failure.<\/p>\n<h2>1. Collecting the Data<\/h2>\n<p>A meaningful run-up depends on capturing the right channels, continuously, from before the machine even begins to move.<\/p>\n<h3>Required Measurements<\/h3>\n<ul>\n<li><strong>Vibration:<\/strong> continuous recording at every bearing location.<\/li>\n<li><strong>Speed:<\/strong> a <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/tachometer\/\">tachometer<\/a> signal so RPM can be tracked moment by moment.<\/li>\n<li><strong>\u0d18\u0d1f\u0d4d\u0d1f\u0d02:<\/strong> a once-per-revolution pulse, which provides the phase reference that makes the Bode plot possible.<\/li>\n<li><strong>Duration:<\/strong> the entire transient, from the start command to stable operating speed.<\/li>\n<li><strong>Sampling:<\/strong> either truly continuous capture or closely spaced time-based snapshots.<\/li>\n<\/ul>\n<h3>Instrumentation Setup<\/h3>\n<ul>\n<li>A multi-channel analyser or data-acquisition system.<\/li>\n<li><a href=\"https:\/\/vibromera.eu\/ml\/glossary\/accelerometer\/\">Accelerometers<\/a> on all bearings, ideally in the horizontal, vertical and axial directions.<\/li>\n<li>An optical or laser tachometer triggered from a strip of <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/reflective-tape\/\">reflective tape<\/a> on the shaft.<\/li>\n<li>Triggered recording armed <em>before<\/em> acceleration starts, so the very first revolutions are not lost.<\/li>\n<\/ul>\n<p>For smaller machines the same essentials \u2014 synchronised amplitude, phase and RPM \u2014 can be gathered with a portable two-channel analyser. The <a href=\"https:\/\/vibromera.eu\/ml\/product\/balanset-1\/\">\u0d2c\u0d3e\u0d32\u0d7b\u0d38\u0d46\u0d31\u0d4d\u0d31\u0d4d-1\u0d0e<\/a> tracks 1\u00d7 amplitude and phase against its laser-tachometer reference as the rotor speeds up, so the data feeding the Bode and waterfall plots can be captured in the machine&#8217;s own bearings on site rather than only on a permanently instrumented train.<\/p>\n<h2>2. Analysis Outputs<\/h2>\n<p>The same recorded data set can be displayed in several complementary ways, each revealing a different facet of the rotor&#8217;s behaviour.<\/p>\n<h3>Bode Plot<\/h3>\n<p>The standard run-up display, drawn as a pair of stacked graphs:<\/p>\n<ul>\n<li><strong>Upper plot:<\/strong> vibration amplitude versus speed.<\/li>\n<li><strong>Lower plot:<\/strong> phase angle versus speed.<\/li>\n<li><strong>Critical speeds:<\/strong> appear as amplitude peaks accompanied by a characteristic 180\u00b0 phase shift.<\/li>\n<li><strong>Multiple plots:<\/strong> one per measurement location and direction.<\/li>\n<\/ul>\n<h3>Waterfall (Cascade) Plot<\/h3>\n<ul>\n<li>A pseudo-3D view of frequency, speed and amplitude together.<\/li>\n<li>Shows the complete spectral evolution across the run.<\/li>\n<li>The 1\u00d7 component tracks diagonally as speed rises.<\/li>\n<li><a href=\"https:\/\/vibromera.eu\/ml\/glossary\/natural-frequency\/\">Natural frequencies<\/a> appear as fixed vertical features.<\/li>\n<li>Where the diagonal 1\u00d7 line crosses a vertical natural frequency, a critical speed is confirmed.<\/li>\n<\/ul>\n<h3>Polar Plot<\/h3>\n<ul>\n<li>A vector plot combining amplitude and phase on a single diagram.<\/li>\n<li>Traces a characteristic spiral as the rotor sweeps through each critical speed.<\/li>\n<li>Widely used in advanced <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/rotor-dynamics\/\">rotor-dynamics<\/a> work.<\/li>\n<\/ul>\n<h2>3. Information the Run-Up Reveals<\/h2>\n<h3>Critical Speed Identification<\/h3>\n<ul>\n<li>Peaks in the amplitude plot mark the critical speeds.<\/li>\n<li>An accompanying 180\u00b0 phase shift confirms genuine <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/resonance\/\">resonance<\/a> rather than a transient bump.<\/li>\n<li>Every critical speed between zero and operating speed is captured.<\/li>\n<li>The measured values can be checked against design predictions.<\/li>\n<\/ul>\n<h3>Damping Assessment<\/h3>\n<ul>\n<li><strong>Sharp peaks:<\/strong> low damping (amplification factor Q \u2248 20\u201350) \u2014 a high-amplification resonance and a potential problem.<\/li>\n<li><strong>Broad peaks:<\/strong> high damping (Q \u2248 5\u201310) \u2014 a gentler, safer passage through the critical.<\/li>\n<li><strong>Quantitative:<\/strong> the damping ratio can be calculated from the peak width using the half-power (\u22123 dB) method, conveniently handled by a <a href=\"https:\/\/vibromera.eu\/ml\/calculators\/damping-ratio-calculator\/\">Damping Ratio Calculator<\/a>.<\/li>\n<\/ul>\n<h3>Separation Margins<\/h3>\n<ul>\n<li>Confirm that the operating speed sits well clear of any critical speed.<\/li>\n<li>A typical requirement is a \u00b120\u201330% margin.<\/li>\n<li>Adequate separation means safe, low-vibration running.<\/li>\n<li>Insufficient separation risks operating on or near a resonance.<\/li>\n<\/ul>\n<h3>Startup Procedure Validation<\/h3>\n<ul>\n<li>Verify the acceleration rate is brisk enough to carry the rotor through each critical speed without dwelling there.<\/li>\n<li>Confirm vibration stays within limits at every speed along the way.<\/li>\n<li>Decide whether any speed hold-points are necessary.<\/li>\n<\/ul>\n<h2>4. Comparison with Coastdown<\/h2>\n<p>A run-up is most powerful when paired with its mirror image, the <a href=\"https:\/\/vibromera.eu\/ml\/glossary\/coastdown\/\">coastdown<\/a>.<\/p>\n<h3>Similarities<\/h3>\n<ul>\n<li>Both identify critical speeds and natural frequencies.<\/li>\n<li>Both use the same analysis techniques and the same plot types.<\/li>\n<li>Together they provide complementary data sets.<\/li>\n<\/ul>\n<h3>Differences<\/h3>\n<ul>\n<li><strong>Run-up:<\/strong> increasing speed, a cold-to-warm thermal transition, and powered acceleration that can push the rotor quickly through a critical.<\/li>\n<li><strong><a href=\"https:\/\/vibromera.eu\/ml\/glossary\/coastdown-analysis\/\">Coastdown<\/a>:<\/strong> decreasing speed, a warm-to-cool transition, and unforced natural deceleration driven only by friction and windage.<\/li>\n<li><strong>Comparison:<\/strong> differences between the two signatures expose thermal or load-dependent effects \u2014 a critical speed that shifts between run-up and coastdown, for instance, points to a temperature-sensitive support.<\/li>\n<\/ul>\n<h2>5.
