Vibration Research- Speaking Events

2018 Speaking Event Schedule

Ryan Becker

Non-Linear Resonance Phase Tracking

April 11, 2018; Wednesday 3:30pm to 4:00pm

Querétaro Convention Center, Querétaro, Mexico

Ryan Becker will be presenting at the ATS Testing Show Mexico


Abstract: Traditionally, when test engineers performed “Sine Resonance Track and Dwell” tests they have controlled the frequency of the resonance with little concern for the phase. There is a significant difference in the product response based on the phase used to track the resonance. Manually controlling the phase can produce better results by finding the most accurate location for the peak transmissibility. Adjusting the phase as necessary serves as an improvement over the traditional resonant frequency phase-tracking method. Engineers are encouraged to maximize the transmissibility value of the resonances while maintaining high quality control.

Evgeny Narubin

Shaker Performance Verification with Vibration Research's Vibration Controller VR9500

April 18, 2018; Wednesday 12:30pm to 1:00pm

Expocentre, Moscow, Russia

Evgeny Narubin will be presenting at the Control Days Moscow

Kevin Van Popering

A Primer on Fatigue Damage Spectrum (FDS) for Accelerated and Reliability Testing

May 1, 2018; Tuesday 1:15pm to 3:15pm Unique Testing Applications and Methods session

Caribe Royale, Orlando, FL

Kevin Van Popering will be presenting at the ESTECH 2018


Abstract: Products experience a variety of vibration stresses in their end-use environment. Eventually, the accumulation of these stresses, or the accumulated fatigue damage, causes a failure in the product. New features in random vibration testing can reliably simulate the full life-cycle of a product in its end-use environment. This innovative process includes the ability to combine many different vibration environments into the same test profile, as well as accelerate the vibration test. Utilizing this method can aid in identifying whether test environments damage a product in the same frequency range as the end-use environment.

Pavel Fiser

Vibration Testing: Sine vs. Random

May 22-24, 2018

Brno Technical University, Brno, Czech Republic

Pavel Fiser will be presenting at the JVE Int'l Conference on Vibroengineering


Abstract: Frequently, our customers will request advice on which of type of test to run on their product; in particular, how to choose between the two most common test types: sine or random. Their desire is to know which test, sine or random, is best to most quickly pinpoint flaws in their product. If they can only run one test, either sine or random, which should it be?

John Holler

A New Method of PSD Estimation

May 23, 2018; Wednesday at 3:55pm

Pasadena Convention Center, Pasadena, California

John Holler will be presenting at the Space Tech Expo USA.


Abstract: it is vital that a random test consistently meets power spectral density (PSD) requirements throughout the test. By nature, random averaging requires time to present in-tolerance and smooth spectral lines. This presentation discusses Vibration Research’s newly developed method of PSD estimation, iDOF®, which provides an accurate and smooth PSD estimate without requiring traditional averaging time. This is the best method available to ensure that a random vibration test meets PSD requirements throughout the test.
