standard that addresses the harder problem of balancing <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/flexible-rotor\/\">flexible rotors<\/a> \u2014 rotors whose shape and unbalance distribution change significantly with speed, particularly as they approach and pass through their bending <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/critical-speed\/\">critical speeds<\/a>. Its full title is <em>&#8220;Mechanical vibration \u2014 Rotor balancing \u2014 Part 12: Procedures and tolerances for rotors with flexible behaviour.&#8221;<\/em> Unlike a <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/rigid-rotor\/\">rigid rotor<\/a>, which can be balanced once at low speed and trusted to stay in balance, a flexible rotor balanced at rest may vibrate violently at its service speed. This standard supplies the specialised multi-speed, multi-plane procedures these rotors demand, and it is the natural companion to <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/iso-21940-11\/\">ISO 21940-11<\/a>, which governs rigid rotors.<\/p>\n<h2>1. Scope and the Classification of Rotors<\/h2>\n<p>The standard applies to any rotor whose unbalance distribution and\/or deflected shape changes with speed. ISO 21940-12 frames the work around typical <strong>rotor configurations<\/strong> with flexible behaviour and the balancing procedures suited to each, rather than a numbered class system. The widely cited five-category scheme below actually originates in the now-superseded ISO 11342:1998 and remains a useful guide to job complexity; rotors range from near-rigid to highly flexible:<\/p>\n<ul>\n<li><strong>Class 1 \u2014 Rigid rotors:<\/strong> behave rigidly across the whole speed range and are handled under ISO 21940-11.<\/li>\n<li><strong>Class 2 \u2014 Quasi-rigid rotors:<\/strong> can be balanced at low speed but may need a <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/trim-balance\/\">trim balance<\/a> at service speed to clean up residual flexing.<\/li>\n<li><strong>Class 3 \u2014 Rotors requiring balancing at several speeds:<\/strong> typically passing through one or more critical speeds, most often balanced with the <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/influence-coefficient\/\">influence coefficient<\/a> method.<\/li>\n<li><strong>Class 4 and 5 \u2014 Highly flexible rotors:<\/strong> such as large turbine-generator shafts, which excite multiple bending modes and need advanced <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/modal-balancing\/\">modal balancing<\/a> to correct each mode.<\/li>\n<\/ul>\n<p>Placing a rotor in the correct class tells the analyst up front how complex the job will be and which procedure to reach for.<\/p>\n<h2>2. Balancing Procedures: Two Core Methods<\/h2>\n<p>This chapter is the technical core of the standard. Its central message is that a low-speed balance alone is insufficient for a flexible rotor and must be augmented by high-speed work that accounts for the shaft&#8217;s bending. ISO 21940-12 organises this work as a family of balancing procedures \u2014 low-speed procedures (designated A to F, such as single-plane, two-plane and balancing in stages during assembly) and high-speed procedures (G to I, carried out at one or more elevated speeds). The high-speed procedures rest on two principal techniques:<\/p>\n<h3>The Influence Coefficient Method<\/h3>\n<p>This versatile, widely used technique places a known <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/trial-weight\/\">trial weight<\/a> in one correction plane at a time and records the resulting <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/vibration\/\">vibration<\/a> response \u2014 both <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/phase\/\">amplitude and phase<\/a> \u2014 at multiple measurement points and across multiple speeds. Repeating this for every plane builds a matrix of influence coefficients that mathematically describes how unbalance in any plane affects vibration at any point and speed. A computer then inverts that matrix to solve for the set of correction-weight masses and angles that simultaneously minimise vibration across the whole operating range. The same mathematics underlies single-plane work; you can explore it interactively with the <a href=\"https:\/\/vibromera.eu\/gu\/calculators\/influence-coefficient-calculator\/\">Influence Coefficient Calculator<\/a>.<\/p>\n<h3>Modal Balancing<\/h3>\n<p>Modal balancing is the more physically intuitive approach: it treats each bending <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/mode-shape\/\">mode<\/a> of the rotor as a separate unbalance problem. The rotor is run at or near a chosen critical speed to maximally excite the corresponding mode shape; vibration measurements then locate the effective &#8220;heavy spot&#8221; for that mode, and correction weights are placed at the points of maximum deflection \u2014 the anti-nodes \u2014 to counteract it. The process is repeated mode by mode for every significant bending mode within the operating range, balancing the rotor one mode at a time. The two methods are not rivals; large machines are often balanced with a hybrid that uses modal insight to choose planes and influence coefficients to refine the weights.<\/p>\n<h2>3. Specifying Balance Tolerances<\/h2>\n<p>The simple <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/g-grade\/\">G-grade<\/a> tolerance that works so well for rigid rotors is generally inadequate for flexible ones, because a single eccentricity figure cannot capture speed-dependent bending. ISO 21940-12 therefore introduces broader tolerance criteria, which may be based on:<\/p>\n<ul>\n<li>Limits on the <strong>residual modal unbalance<\/strong> for each significant bending mode.<\/li>\n<li>Limits on the <strong>absolute shaft vibration amplitudes<\/strong> at specified locations and speeds, especially at the service speed.<\/li>\n<li>Limits on the <strong>forces transmitted to the bearings<\/strong>.<\/li>\n<\/ul>\n<p>These vibration- and force-based limits tie the acceptance criteria to in-service severity standards such as the <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/iso-20816-1\/\">ISO 20816<\/a> series, rather than to a single residual-unbalance number.<\/p>\n<h2>4. Verifying the Final Balance State<\/h2>\n<p>Acceptance of a flexible rotor is fundamentally different from a rigid one. A rigid rotor is verified at a single speed; a flexible rotor must be confirmed in balance throughout its <em>entire<\/em> operating range. After the final corrections, the rotor is taken through a <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/run-up-analysis\/\">run-up<\/a>, with vibration continuously monitored at key locations such as the bearings and the points of maximum deflection. The rotor is accepted only if the measured vibration stays below the pre-defined limits at all speeds \u2014 particularly while passing through each critical speed and while dwelling at the maximum continuous operating speed. This comprehensive check confirms that the rotor&#8217;s full dynamic behaviour has been brought under control.<\/p>\n<h2>5. The Field Dimension and Practical Tools<\/h2>\n<p>While much flexible-rotor work happens on high-speed balancing rigs, the same amplitude-and-phase measurement skills apply to <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/field-balancing\/\">field balancing<\/a> and trim balancing once a machine is installed. A portable two-channel analyser such as the <a href=\"https:\/\/vibromera.eu\/gu\/%e0%aa%89%e0%aa%a4%e0%ab%8d%e0%aa%aa%e0%aa%be%e0%aa%a6%e0%aa%a8\/balanset-1\/\">\u0aac\u0ac7\u0ab2\u0abe\u0aa8\u0acd\u0ab8\u0ac7\u0a9f-1 \u0a8f<\/a> captures 1\u00d7 amplitude and phase in the machine&#8217;s own bearings, computes influence coefficients, and lets an engineer apply and verify a trim correction at operating speed without disassembly \u2014 a frequent need for Class 2 quasi-rigid rotors that pass their shop balance yet still flex slightly in service. For installed medium and large machines, the dedicated in-situ procedures and safeguards of <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/iso-21940-13\/\">ISO 21940-13<\/a> apply alongside this part.<\/p>\n<h2>6. Key Concepts to Carry Away<\/h2>\n<ul>\n<li><strong>Flexible vs rigid behaviour:<\/strong> a rotor is treated as flexible once its operating speed reaches a significant fraction \u2014 typically above 70% \u2014 of its first bending <a href=\"https:\/\/vibromera.eu\/gu\/glossary\/natural-frequency\/\">natural frequency<\/a>. As it spins faster, centrifugal forces bend it and change its unbalance.<\/li>\n<li><strong>Critical speeds and mode shapes:<\/strong> knowing the rotor&#8217;s critical speeds and the shapes it bends into at each is essential; every mode is a separate balancing problem.<\/li>\n<li><strong>Multi-plane, multi-speed:<\/strong> corrections in several planes, informed by measurements at several speeds, are the rule rather than the exception.<\/li>\n<li><strong>Modal balancing:<\/strong> a powerful strategy in which weights are added specifically to counteract the unbalance of each bending mode at its anti-nodes.<\/li>\n<\/ul>\n<hr>\n<p><a href=\"https:\/\/vibromera.eu\/gu\/glossary\/\">\u2190 Back to Main Index<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>An overview of ISO 21940-12, the standard that specifies the complex procedures and tolerances required for balancing flexible rotors.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"ai_generated_summary":"","footnotes":""},"categories":[109,112],"tags":[],"class_list":["post-20606","glossary","type-glossary","status-publish","hentry","category-glossary","category-iso-standards"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/glossary\/20606","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/glossary\/20606\/revisions"}],"predecessor-version":[{"id":101448,"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/glossary\/20606\/revisions\/101448"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/media?parent=20606"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/categories?post=20606"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/gu\/wp-json\/wp\/v2\/tags?post=20606"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
