Advanced Vibration Control

Overview

This course is targeted at solving complex vibration problems involving transient and forced vibrations; resonance, isolation and damping. It is partial preparation for the ISO/IEC 18436-2:2014 Vibration Analyst Category IV Certification Exam. Workshops and demonstrations are scheduled throughout the training course to exemplify curricular theory and applications.

Instructor

BOB SAYER, P.E. is the President of the Vibration Institute and owner of Applied Structural Dynamics (Westerville, Ohio). He has over forty years of experience as a mechanical and structural engineering consultant to a wide range of industries including pulp & paper, mining & metals, fossil-fuel & nuclear power generation, petrochemical, food processing, glass manufacturing, and aerospace & defense. Mr. Sayer provides analytical and experimental dynamic analysis of mechanical equipment for design projects, structural and mechanical failure studies, and process reliability and efficiency studies. Mr. Sayer holds engineering degrees from Ohio University (BSCE), Cleveland State University (MSIE), and Purdue University (MSCE). He had the honor and fortune of collaborating with the late Art Crawford, a pioneer of vibration analysis, on numerous projects. Mr. Sayer is a regular contributor at technical conferences and has published over 50 technical articles and co-authored 2 chapters in “The Simplified Handbook of Vibration Analysis”.

Course Content

Transient Free Vibrations
Damped and undamped free vibrations of single and multiple degree-of-freedom systems, impact testing, log decrement calculation, equivalent spring calculation, and natural frequency calculation.

Workshop I: Free Vibrations
Forced Vibrations
Forced harmonic response, damping analysis, and base motion response. Forced response to periodic non-harmonic and impulse forces. Sensitivity of modes to placement of dynamic forces. Case histories involving force modification as a form of vibration control.

Workshop II: Forced Vibrations
Vibration Control Methods I
Tuning natural frequencies to avoid resonance by changing stiffness and/or mass. Linear & non-linear stiffness, and temperature & strain rate effects on stiffness. Reducing forced vibration by adding damping . Modal participation considerations when changing stiffness or mass. Case histories using detuning methods.

Vibration Control II
Theory and application of tuned Dynamic Vibration Absorbers (DVA) and Auxiliary Mass Dampers, including case histories.

Workshop III: Vibration Control
Vibration Control Methods III
Theory of Dynamic Force Isolation, Advantages and Disadvantages of different isolator types. Decoupling of isolated system from support system. Case histories involving proper and improper use of isolation.

Workshop IV: Isolation
Basic Rotor Dynamics
Basic Rotor Dynamics Concepts, single & multiple degree-of-freedom models, modal mass, mode shapes, limitations of different modeling techniques, support & rotor stiffness asymmetry, flexible impellers, gyroscopic effects, centrifugal stress stiffening, Lomakin effect in pump rotors, tuning techniques for rotors.

Certification Exams are offered:

  1. The day AFTER VI training courses 
  2. Anytime at VI offices
  3. At a USA location near you with a pre-approved VI proctor
  4. Through our International Representatives

How:

  1. Register for a course and exam
  2. Register for just the exam (if you already have the training requirement, or are getting training elsewhere)
  3. Find a USA proctor by contacting us
  4. Contact an International Representative in your country

The cancellation of and transfer to a training course within the same calendar year will be honored, provided that written notification is received by the Institute office via e-mail or mail no later than ten (10) business days before the first day of the scheduled course. If registration for a training course is cancelled without transfer to another course within the same calendar year, a $250 cancellation fee will be assessed. A $500 administrative fee will be charged for cancellations received less than ten (10) days from the start date of the registered training course. Additional cancellation fees will be applied for exam cancellations. Absentees for the course will not receive a refund. Please contact the Vibration Institute staff directly regarding discounts for multiple registrations from the same organization.
