Latest Developments in Vibration Testing

Date: July 21, 2017 - 14:25 – 14:45

Centara Grand & Bangkok Convention Centre at Central World in Bangkok, Thailand

Mark Chomiczewski will be presenting at the Automotive Engineers Forum..

 

Abstract: The goal of testing any product is to reliably predict how it will perform in its expected end-use service environment. Companies who are performing vibration testing are concerned with product durability and want to determine how long their product will last when exposed to various vibration environments. An additional goal may be to find ways to accelerate their existing vibration testing in order to bring new products to market, faster. Considering this, how does your current laboratory vibration testing correlate with the actual end-use service environment? This presentation will attempt to help you answer this question and also answer other commonly asked questions such as “which test is more severe, sine or random vibration”, or “if I run my random vibration test for 1 hour, how many hours does this equate to in the real-world”, or “is my current vibration testing considering periodic shock events”, and finally “can I accelerate my current vibration testing?"


Dan Pichan

Fatigue Damage Spectrum Application Study

Date: August 16, 2017 - 14:00 - 14:30

ProMagno Centro De Eventos, São Paulo, Brazil

Dan Pichan will be presenting at the SAE Brasil Automaker Symposium of Testing & Simulation..

 

Abstract: Damage accumulates on all products because of vibration. The damage from vibration stresses on a product eventually results in catastrophic failures. Understanding and quantifying the “damage” characteristics of an environment or a combination of environments allow an engineer to avoid catastrophic failures. The fatigue damage spectrum is used to analyze time history files, evaluate qualification test standards as compared to actual end use environments, and define new vibration tests representative of the actual use of a product. This presentation addresses the methodology used to analyze, compare and combine field environments as well as generate the appropriate test profile based on the real-world vibration exposure a product will experience.

Understanding Transducer Calibration and Recent Technological Improvements

Date: August 17, 2017 - 1:00-2:00 pm

Gaylord National Convention Center in National Harbor, Maryland

Aaron Offringa will be presenting at the NCSLI Workshop and Symposium 2017..

 

Abstract: Transducer calibration is of upmost importance in any laboratory environment to ensure the accuracy of data. Significant advancements have been made with accelerometer calibration systems and now companies can perform highly accurate calibrations in-house with uncertainties equal to or exceeding those provided by an outside source. These advancements include the potential for test automation, superior reporting capability, tighter tolerances, the ability to read/re-write TEDS information, and faster turn-around times. Performing transducer calibrations in-house eliminates the need to send units outside of the organization, reduces downtime, and saves money. The most common method of calibration is the NIST approved back-to-back calibration method. The three primary components are: a controller, a back-to-back accelerometer, and a calibration shaker. The sensor under test is properly torqued to the reference standard and vibrated at multiple discrete frequencies across a specified frequency range. The responses from the transducer under test are compared to the responses of the known standard and a new sensitivity is calculated from this data. The opportunity for error exists from many sources, many of which can be controlled by following industry standards and processes. The potential for mistakes can be minimized with a well-designed system and an understanding of the calibration process.


Jade Vande Kamp

Fatigue Damage Spectrum – Application Study

Date: September 13, 2017: 10:15 – 11:00am

Tokyo Big Sight, Tokyo, Japan

Jade Vande Kamp will be presenting at the Test 2017.

 

Abstract: The accumulated damage that a product experiences in the field due to the variety of vibration stresses placed upon it will eventually cause failures in the product. The failure modes resulting from these dynamic stresses can be replicated in the laboratory and correlated to end use environment to validate target reliability requirements. This presentation addresses three fundamental questions about developing accelerated random vibration stress tests. Question #1: What random profile is needed (and for how much time) to accurately simulate the end use environment over the life-cycle of my product? Question #2: My product operates in many different vibration environments, how can I confidently combine them into one accelerated test? Question #3: How can I use the FDS to accelerate my test?

Fatigue Damage: Combine, Compare and Quantify

Date: September 19, 2017: 11:45 am

Shanghai World Exhibition & Convention Centre, Shanghai, China

Ryan Becker will be presenting at the Testing Expo China 2017.

 

Abstract: Fatigue damage is a common and predictable cause of damage in the supply chain. The Fatigue Damage Spectrum (FDS) is an abstraction that helps engineers make decisions in several different ways. First, the FDS can be used to design and shorten a random vibration test based on combined time-domain data. Second, the FDS can be used to compare time-domain waveforms in terms of fatigue. Third, being able to quantify the end-use environment to the vibration profiles running on the shaker gives confidence when going from field to lab. The ability to combine, compare and quantify environments and testing makes the FDS a powerful tool for test design and product analysis.
