CAT IV – Advanced Vibration Control (AVC)

AVC is targeted at solving complex vibration problems involving transient and forced vibrations; resonance, isolation and damping in both structural dynamic and rotor dynamic systems. It is partial preparation for the Vibration Analyst Category IV Certification Exam. The workshops and case studies scheduled throughout the training course are used to illustrate theory and applications.

All registered attendees in the Advanced Vibration Control training course will receive the following:

• Course Manual
• Workbook with vibration related questions requiring a solution and Equation Sheet
• Calculator
• Electronic Certificate of completion

It is recommended that attendees review the Body of Knowledge found in ISO 18436-2 Annex A, which can be found at vi-institute.org under Certification, prior to the training course.

The AVC course begins daily at 1:00 P.M. on Monday and ends at 5:00 P.M. 

Tuesday - Thursday   8:00 A.M - 5:00 P.M.

Friday 8:00 A.M - 4:00 P.M.

Training and Workshops Include:

1.0 Introduction; Effect of vibration level on fatigue, structural vs. mechanical vibration severity evaluation, industry specific severity standards. Workshop #1

2.0 Transient Free Vibrations; Damped and undamped free vibrations of single and multiple degree-of-freedom systems. Modal testing to determine natural frequencies, damping, and mode shapes. Intro to the concept of modal participation. Viscous versus hysteretic versus friction damping.  Log decrement, equivalent spring and natural frequency calculations. Tuning natural frequencies to avoid resonance by changing stiffness and/or mass. Linear & non-linear stiffness, and temperature & strain rate effects on stiffness. Workshop #2

3.0 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 #3

4.0 Basic Rotor Dynamic Vibration Control; 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, and Lomakin effect in pump and multi-stage blower rotors.  Basic Rotor Instabilities on Oil-Film Bearings.  Rigid Body versus Elastic Modes.  Natural frequency tuning techniques for rotors. Workshop #4

5.0 Basic Structural Dynamics; Dynamic response of structural components of machines and flexible floor framing systems. Natural frequency tuning techniques to reduce vibration of structures. Theory and application of tuned Dynamic Vibration Absorbers (DVA) and Auxiliary Mass Dampers. Workshop #5

6.0 Interaction of Rotor Dynamics with Structural Dynamics; Evaluation of response of systems where there is significant interaction between rotor and structural dynamics using computer-aided solution techniques and manual multi-degree-of-freedom calculation methods. Workshop #6

7.0 Isolation; Theory of dynamic force Isolation, advantages and disadvantages of different isolator types, stability requirements for isolation systems, decoupling of isolated systems from support system. Isolation of Shock & Impulses versus harmonic forces. Case histories involving proper and improper use of isolation. Workshop #7

8.0 Systems subjected to Dynamic Pressure Pulsations; Sources of pulsations in pumps, fans & compressors, structural dynamics of piping and ductwork, acoustic resonance, vibration severity criteria for pipes, vortex shedding problems and solutions.  Pulsation Control using pulsation dampeners and orifices. Workshop #8
