DTS HQ – Principles of Dynamic Data Collection – Training Event Recap

| Principles of DAS Training Day, November 15, 2018

Over 50 customers and industry partners joined DTS for a special training event Principles of Dynamic Data Collection on November 15 at DTS headquarters in Seal Beach, California. The training featured a variety of speakers and topics designed to share practical knowledge with anyone involved in dynamic testing. The day kicked off with a session presented by Mike Beckage, DTS CTO and co-founder, focused on data acquisition best practices. Fundamental topics including sensor theory, limitations, grounding & shielding and shunt & empirical checks kept the audience engaged and asking questions, whether they were seasoned test professionals or new to the industry.

The audience also included a select group of engineering and injury biomechanics students from Cal State Los Angeles (CSULA). “It was great to have students attend our training day  . . .  especially at a time when critical thinking, education and exposure to real-world solutions are so important,” said Beckage.

DTS developed this exclusive seminar based on sharing practical field knowledge and best practices learned over years of helping customers solve both common and unique challenges. “DTS decided to put our years of experience to work and share our knowledge. There’s no school that teaches this, even though mastering these skills are key to anyone who does test data collection,” added Steve Pruitt, DTS CEO and co-founder.

The afternoon sessions were divided into two different industry topics. Track A focused on Injury Biomechanics & Automotive Crash Safety and was led by Steve Moss, DTS Director of ATD Systems. With his extensive industry experience, Moss shared the history of crash test dummies, officially called anthropomorphic test devices (ATD), why in-dummy DAS is important and the development of WIAMan, the first instrumented blast test ATD developed by DTS for the U.S. Army. Track B focused on Aerospace & Industrial applications, new DTS data acquisition systems engineered to support time and synchronization, streaming capabilities, IEEE 1588 and more.

The day wrapped up with tours of the offices which showcased DTS’s in-house engineering, software, firmware, manufacturing and QA capabilities – all of which are based at the Seal Beach headquarters.

New Helmet Testing Hits Hard at Improving Safety

New Helmet Testing Hits Hard at Improving Safety

New ways of testing and analyzing football head injuries caused by helmet-to-helmet hits is approaching a touchdown.  The University of Alabama at Birmingham’s (UAB) Department of Mechanical Engineering is developing new testing methodologies using crash test dummies to improve helmet testing and ultimately reduce concussions and traumatic brain injuries (TBI).

While there are recorders that can be attached to the outside of a helmet to alert coaches and medical staff of possible concussions, these devices track helmet motion and generally do a poor job of tracking actual head motion. The UAB research team wants to improve the helmets themselves, starting with the testing process, so they are putting the sensors and recorders inside crash test dummy heads for even more biofidelic impact data.

UAB’s unique test facility recreates the collisions players experience on the field, based on analyzing hours and hours of game footage. An 80-foot railed track with a motorized sled recreates actual impacts using two crash dummies geared up in protective football equipment. Initially the dummies were wired up to exterior data acquisition systems, but there were issues with tangled cables that restricted free-flight test dynamics. The solution: miniature DTS SLICE NANO data recorders plus triaxial linear accelerators and angular rate sensors that are embedded inside the dummy head – eliminating any trailing cables. The system records each collision, calculates the velocities of the players involved, the locations of impact on each player’s helmet and more. This data is critical to support UAB’s goal to identify helmets that best protect players from concussions, as well as encouraging the design of new, even safer helmets. The institution’s new partnership with VICIS, a helmet technology company, will aid that goal even further.

“Right now, there are no football helmet standards that specifically address concussions,” said Dean Sicking, Ph.D., professor in UAB’s Department of Mechanical Engineering.  “The DTS data recorders and sensors collect the relevant data that we need from replicated real-world hits in order to ascertain what kind of forces the hits cause.  Ultimately, we can gather enough data to see whether helmet A or helmet B performs better in protecting against concussions.”

UAB looked to Diversified Technical Systems (DTS) for their expertise in biomechanics and occupant safety testing. The California-based company is known for miniature, rugged data recorders and sensors used for crash, blast and safety testing worldwide. DTS designed the first in-dummy data acquisition system (DAS) for the WorldSID, a side impact dummy developed and used in automotive regulatory testing.  Most recently, DTS completed building  the first military blast test dummy (WIAMan) for the U.S. Army with next generation data recorders and sensors inside. This breakthrough of moving data recorders inside the test dummies has significantly changed the face of safety testing by improving the fidelity of the data and the efficiency of the test set-up.

“DTS systems are so small that they really are a game-changer in this important work of improving player safety,” says Hans Hellsund, Director of Sales for DTS. “For over 26 years our technology has been focused on helping keep people safer, whether it’s with auto manufacturers, aerospace testing, or soldier protection,” adds Hellsund.

Army program completes, delivers technical data package for newest test manikin

 

ABERDEEN PROVING GROUND, Md. (June 2018) – The U.S. Army Research, Development and Engineering Command, Army Research Laboratory’s Warrior Injury Assessment Manikin, or WIAMan, Engineering Office delivered the WIAMan Generation 1 manikin technical data package to representatives of the U.S. Army Program Executive Office Simulation, Training and Instrumentation located in Orlando, Florida,during a ceremony held at APG May 31.The WIAMan Gen 1 is the world’s first test manikin that is purpose-built for military use in underbody blast testing of ground vehicles in live-fire test and evaluation.In accordance with the Army-approved schedule for transition of the WIAMan program from ARL to the Assistant Secretary of the Army (Acquisition, Logistics and Technology), the on-time delivery of the package, which includes drawings, specifications and manuals for the test manikin, marks the start of the formal handover of management of the WIAMan program from the science and technology community to the material developer.

“The cooperation between government and industry has been a model of how a complex development program can be completed on an expedited schedule, within budget,” said Steve Pruitt, DTS President and CEO. “Starting from a concept technical data package in early 2015 to delivery of four WIAMan Gen 1 manikins in less than three years is a remarkable achievement.”Pruitt said WIAMan will significantly increase the Army’s capability to assess probably of injury to warfighters in a wide range of underbody blast events—saving lives and reducing injuries by helping the Army and industry to design vehicles that best protect them. According to Hughes, the WIAMan package is a key delivery to the material developer for the continued development and production of WIAMan manikins to support the upcoming armored multi-purpose vehicle under-body blast testing in fiscal 2020.“Maintaining our technological advantage in warfare is found in dogged scientific advancements and decisive programs that are steadfast in its pursuit,” said Col.Scott McIntosh, PEO STRI Joint Project Manager Medical Modeling and Simulation.“None are more crucial than those that underpin the survivability of our warfighters.”He said the collaborative work between the WIAMan Engineering Office and JPM MMS embodies this determination to save lives.

“Our two offices’ shared commitment to the program’s purpose combined with an innovative strategy with our industry partners has provided the DOD a cutting-edge test capability that is irreplaceable,”McIntosh said.“Our work illustrates that when the entire process is agreeably focused on the problem set, challenges can be quickly surmounted. Our work will be used for decades to support force wide modernization efforts and evaluate threats to our service members.”The formal transition of the management of the manikin from ARL to PEO STRI culminated in a technology readiness level 6 live-fire test demonstration held at APGJune 13.Army S&T laboratories will continue to execute additional critical elements of the effort, to include ongoing biomechanical research and development of a virtual WIAMan finite element model.
