Using Kurtosion to accelerate structural life testing

Holger Boller
European managing director
Vibration Research Europe GmbH
Germany
Life testing using controlled random excitation is a long-accepted means of finding design and/or assembly flaws. Class general broadband spectra, such as the NAVMAT profile, permit testing without initially knowing the specific resonances of a new package. Now kurtosis control allows such tests to be conducted in a fraction of the time required for a Gaussian drive signal to precipitate failures. However, kurtosis control must be properly implemented to circumvent interference from the Central Limit Theorem. A unique feature within the Vibration Research Corporation (VRC) Kurtosion process allows resonant fatigue and simple static failure tests to be accelerated.

Battery impact and crash simulation

Daniel Ruiz
Business development
ENCOPIM, S.L.
Spain
Currently, regulations for automotive battery systems include three types of mechanical tests meant to assess the safety of batteries during a crash: shock, mechanical integrity and penetration tests. However, requested velocities on these tests are relatively low, and just assess, for instance, the potential damage to the battery system when the car is driven against a bollard or crosses a deep gutter. To simulate realistic crash conditions, tests should be conducted at much higher velocities than the regulatory standards request. In addition to adapting these tests to more realistic conditions, the relevant parameter to be accurately controlled is no longer only acceleration, it is either velocity or position, and traditional crash simulation controls do not meet these requirements. New developments on testing systems to overcome above limitations will be presented.

Press-in connections are state of the art for safety-critical applications in automotive applications. The current IPC and IEC regulations have so far made insufficient reference to this aspect. In this presentation, case studies are used to consider criteria relevant to evaluation in the findings of non-destructive testing and metallographic preparation. This also applies to the evaluation of the deterioration of insulation paths. Additionally, the significance of the features and criteria found is presented from the point of view of a third-party laboratory for product qualification and failure analysis.

Characteristics and peculiarities of a fixture for vibration tests

Luca Marzano
Fixture designer
MPLD Srl
Italy
During the presentation, the concepts that define the basic characteristics of a vibration test device and the parameters that determine its realization will be presented. This will be the starting point to propose these devices in a different way and, if possible, to widen their scope. MPLD will present solutions to optimize the entire product validation cycle without considering the vibration fixtures, other devices and tests as distinct elements, but as components that need to be synchronized to work together towards the same goal.

How the test environment can be managed to get repeatability

Julien Ley
Sales engineer
Greenmot
France
One of the main challenges of a test laboratory is to provide data with the utmost level of precision and repeatability to customers. With more than 10 years of experience in the field, Greenmot has built a very specific methodology to address this. The methodology involves mastering every aspect of the test performance: environment (hub dyno climatic test cells) + driving (automated G-Robot) + instrumentation (w/ in situ setup) + refueling solutions (in-house w/ HP charger, H2 refills…). Today, Greenmot works on a regular basis with OEMs from all industries: passenger cars, commercial and industrial vehicles, defense, off-road and construction vehicles.

Bidirectional programmable DC power supplies for testing high-voltage and low-voltage equipment

Wolfgang Horrig
Global sales manager
EA Elektro-Automatik GmbH & Co KG
Germany
High- and low-voltage equipment such as onboard chargers, DC-DC converters, traction inverters and battery management systems installed in electrical vehicles (HEV, PHEV, BEV) require intensive validation, performance and safety testing prior to their integration. EA Elektro-Automatik’s range of bidirectional programmable DC power supplies are ideal to efficiently test all automotive devices for voltages from 3.2V through 2,000V and currents of up to several thousand Amperes. In load mode, these supplies are regenerative, meaning the energy taken from the equipment under test is converted into AC and fed back into the mains supply.
