MESSRING’s advanced data acquisition system for new calibration lab of GSK Protech in China
Developing crash-test dummies is a core focus of the automotive industry dedicated
to improving the protection of passengers and pedestrians. Based in Munich, the company MESSRING is a specialist in this field and has been manufacturing
installation and data acquisition systems for the crash-test segment since 1968. The company also focuses on further developing and adapting the award-winning
M=BUS data acquisition system for crash-test dummies and other components.
The latest innovation is the complete sensor and data acquisition system for the
most modern side-impact dummy on the market, the so-called “WorldSID 5th Small Female Dummy”. This expertise in particular is highly valued all over the globe, as
demonstrated by the new project for supplier GSK Protech in China. Here in Nanjing, MESSRING has already built a crash-test facility and now a cutting-edge calibration
lab is being constructed to maintain dummy models equipped with the most modern data acquisition system.
Since MESSRING launched the M=BUS data acquisition systems onto the market in
2006, it has been upgraded continuously to accommodate the latest developments in the industry. The engineers
have had to overcome new challenges time and again, especially covering the in-dummy data acquisition systems
. This ongoing development is currently being impressively demonstrated by the new WorldSID (Worldwide Harmonized Side Impact Dummy - 5th Small Female Dummy) data acquisition systems.
The primary benefit of the progressive BUS solution is that you can connect up to 32 data acquisition units with
just one coaxial cable. This significantly accelerates the work of the test engineers and ensures a maximum
bandwidth of test scenarios as well as clean, precise data acquisition results during the crash test. Regardless
of whether three or six channels are used to record data, the small data acquisition modules always ensure full
signal strength for all in-dummy components, which are controlled via a gateway. The M=BUS technology also
offers additional significant benefits: it improves heat distribution thanks to the decentralized design, and the data
acquisition system has practical ID modules that ensure the mass properties of the dummies remain unchanged.
Cutting-edge dummies such as the 5th Small Female are equipped with extremely sensitive data acquisition
technology and therefore have to be recalibrated after just a few tests, which is why it’s so important to have a
good calibration lab like the one being built in Nanjing. In addition to hardware, MESSRING also offers its own
dummy calibration software, CalSoft, which plays a key role in each crash test. The software controls test rigs,
assesses data, and is essential for ensuring test reproducibility. With so many different test runs and dummy
models, it’s also necessary to use a software that’s powerful enough to fulfill all the test requirements and guidelines.
MESSRING’s expertise in data acquisition and the corresponding technology convinced the Chinese car
component supplier GSK Protech to build a cutting-edge calibration lab in Nanjing equipped with MESSRING
technology, having already constructed a crash-test facility. The laboratory is scheduled for completion at the
end of 2014. “We look forward to equipping a state-of-the-art lab and offering our customers optimum support
and cutting-edge technology with our very own calibration software in Nanjing. Particularly in terms of
technological equipment and dummy calibration, this lab will be like no other in Asia,” explained Dierk Arp, CEO of MESSRING.
