Balancing of Rotating Machinery (BRM)

BRM covers single and basic two-plane balancing techniques. It includes both field balancing and shop (balancing machine) balancing. Topics such as pre-balance checks, influence coefficients, balance quality and tolerances, residual unbalance testing and case histories are included. It is partial preparation for the Vibration Analyst Category III and IV Certification Exams, and Balancing Specialist Exam. All registered attendees in the Balancing of Rotating Machinery training course will receive:

• Course Training Manual
• Printed Copy of Course PowerPoints
• Workbook with examples, vibration related questions requiring a solution as found in Vibration Institute Guideline No. 1 requirement for qualification and assessment of balancing personnel.
• Calculator
• Ruler,
• Balancing Tools
• Certificate of Course Completion

The BRM training is a four and one-half day course and will begin at 1:00 p.m. and conclude at 6:00 p.m. on Monday. It will then begin at 8:00 am and conclude at 5:00 pm daily Tuesday through Friday. Subject to change.

BRM Course Content Includes Basic aspects of machine balancing, single plane balancing, two plane balancing techniques, turbine generator balancing, roll balancing, fan balancing and shop balancing.

There is a work shop supporting each chapter. The student will test their knowledge and understanding of the material presented for that chapter by completing the workshops during the time allowed in class. The instructor will then review the workshop with the class. The student’s time and understanding of the work shop materials will aid them in their preparation for the exam.

Training and Workshops Include:

1. Introduction to Balancing; mass unbalance, weight effects, measurements, equipment, pre-balancing checks, trial weights and types of unbalance.
2. Single Plane Balancing with Graphical Solution; vector method, balance sensitivity, phase lag, one shot method, weight addition, weight removal, weight splitting and combining.
3. Residual Unbalance and Acceptable Vibration Limits; permissible unbalance, permissible eccentricity, permissible vibration, and overall limits.
4. Single Plane Balancing by Influence Coefficients; vector math, application of influence coefficients, and balancing with proximity probes. 
5. Shop Balancing; rotor classification, rotor supports, drive types, foundations, instrumentation, keyed rotors, arbors, rotation, speed, correction and residual unbalance.
6. Bodé and Polar Plots; critical speed, phase lag, first mode, second mode and a split critical.
7. Introduction to Two Plane Balancing; types of unbalance, static couple, influence coefficient, near plane and far plane effects.
8. Field Balancing; fans, roll balancing, spindle balancing, natural frequencies, mode shapes, and case histories.
