Neck Injury Response in High Vertical Accelerations and its Algorithmical Formalization to Mitigate Neck Injuries.

Tank Automotive Research, Development and Engineering Center (TARDEC) conducted a comprehensive analysis of data collected during the evaluation of head and neck impact during injurious and non-injurious loading. This evaluation included impact velocity, helmet to roof clearance, and neck angle using a fully instrumented Hybrid III head and neck assembly. The results of this effort were compared against post mortem human subject (PMHS) data from similar testing conducted in conjunction with the Warrior Injury Assessment Manikin (WIAMan) program. The results identified the most severe helmet to roof clearance and neck angles. TARDEC used this knowledge as the foundation for continued research into head and neck impact injury mitigation through the use of passive technology and interior vehicle design.

Under-Body Blast Mitigation: Stand-Alone Seat Safety Activation System

This work is based on a current project funded by the United States Army Small Business Innovation Research (SBIR) Program and is being conducted with the Tank Automotive Research, Development and Engineering Center (TARDEC) Ground Systems Survivability (GSS) Team and Paradigm Research and Engineering. The focus of this project is to develop an advanced and novel sensing and activation strategy for Pyrotechnic Restraint Systems, Air Bags and other systems that may require activation. The overriding technical challenge is to activate these systems to effectively protect the Soldier during blast events in addition to Crash, Rollover and Other Injury Causing events. These activations of Pyrotechnic systems must occur in fractions of milliseconds as compared to typical automotive crashes. By investigating systems outside of typical accelerometer based applications and activations, the potential exists to exploit systems that require little power, are self-contained and provide the required output for the desired result. As such Constant-Flux Magnetostrictive Sensors shall be evaluated in a self-contained environment to provide the output during these events. By activating the Pyrotechnic Restraint Systems and Air Bag Systems early in Blast Events, the systems can Restrain the Occupant and provide flail protection from surfaces within the vehicle. As the system is developed various test scenarios will be introduced to activate these systems and design a robust sensing and activating strategy. Language: en

Development and model-based transparency analysis of an Internet-distributed hardware-in-the-loop simulation platform

This paper summarizes efforts to integrate, for the first time, two geographically dispersed hardware-in-the-loop simulation setups over the Internet in an observer-free way for an automotive application. The two setups are the engine-in-the-loop simulation setup at the University of Michigan (UM) in Ann Arbor, MI, USA, and the driver-in-the-loop ride motion simulator at the US Army Tank-Automotive Research, Development and Engineering Center (TARDEC) in Warren, MI, USA. The goal of such integration is to increase the fidelity of experiments and to enable concurrent geographically dispersed systems engineering. First, experiments with the actual hardware are presented. The concept of transparency is discussed, and the infeasibility of performing a baseline experiment with ideally integrated hardware is presented as a challenge to characterize the transparency of the experimental setup. This motivates the second half of the paper, in which a model-based approach is taken to analyze the transparency of the system. The conclusion is that an observer-free solution is feasible for integrating the two pieces of hardware over the Internet in a transparent manner, even if the nominal delay is increased by four times. It is also found that different signals in the system can exhibit different levels of transparency.

Measuring Lateral Tire Performance on Winter Surfaces

Abstract The Army has approved and funded an Army Technology Objective (ATO) entitled “High Fidelity Ground Platform and Terrain Mechanic Modeling.” This ATO is being jointly performed by the Engineer Research and Development Center (ERDC) along with the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) and the Army Research Laboratory (ARL). Two of the ERDC laboratories are participating in the ATO: The Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, NH, and the Geotechnical and Structures Laboratory in Vicksburg, MS. One of CRREL’s major milestones for the ATO is to extend two-dimensional ground contact models for the TARDEC Real-time Simulator to full three-dimensional functionality by including the lateral forces. Central to that requirement is an understanding of lateral forces on all-seasons terrain. While modeling of vehicle tire lateral force interactions for typical hard paved surfaces is well understood, there is a need to translate that understanding in a consistent manner into off-road terrain and low-friction surfaces. The experimental work described in this paper is fundamental to gaining the required understanding. The experimental work, performed with instrumented vehicles, was accomplished via a contract with the Nevada Automotive Test Center. The testing included both lateral and longitudinal traction tests on winter surfaces. The surfaces included ice, packed snow, and disaggregated snow. The two principal tires tested were an all-season LT235/75R15 that has been the subject of many tests on the CRREL instrumented vehicle, and a tire used on the military’s HMMWV, size 37×12.50R16.5. For each tire and surface, tests at a minimum of two inflation pressures were conducted. For each surface/tire/inflation variant a minimum of ten replicate data sets were obtained. This paper reports the results of the tests and the analysis conducted to date.

Vetronics technology testbed

The Vetronics ( ve hicle elec tronics ) Technology Testbed (VTT) is a research project being developed by the U.S Army Tank-Automotive Research Development and Engineering Center (TARDEC). The main objective of the VTT is to demonstrate the capability of one crewmember to perform the functions of both the vehicle Commander and Driver. The demonstration was required to take place while operating over military-significant terrain and while performing a military-significant mission. In order to accomplish this objective, TARDEC adapted and integrated crew station designs (Figure 1) developed under the Crewman's Associate Advanced Technology Demonstrator (ATD).In addition, hardware and software developed under the INter-Vehicle Embedded Simulation Technology (INVEST) Science and Technology Objective (STO) was used to create realistic simulated operating and training scenarios for the crewmembers. Another goal of the project was to demonstrate the technology in a platform comparable (mobility, size, weight, etc.) to the currently envisioned Future Combat Vehicle (FCV).Several key technologies and capabilities were incorporated into the VTT and include the following:• Drive-by-wire capability• Day and night operation• Indirect vision as the primary vision• Three-dimensional (3D) audio system• Speech Recognition and Generation• Multi-function displays with touch screens• Embedded simulation as an enabling technology for embedded training, mission rehearsal, battlefield visualization and after action review• WSTAWG Operating Environment (OE) [1]• Joint Variable Message Format (JVMF) [2]• Communication via voice intercom and SINCGARS radios

Development of a low VOC chemical agent resistant coating for use with supercritical CO2

AbstractThe regulatory environment surrounding the application of coatings is growing increasingly challenging. Complying with these regulations has spawned a myriad of new technologies such as waterborne, powder, and (more recently) the use of carbon dioxide for viscosity reduction. The U. S. Army Tank‐Automotive Research, Development, and Engineering Center (TARDEC) has sponsored a program under the Army Acquisition Pollution Prevention Program involving the University of Detroit Mercy (UDM) to develop a lower VOC (volatile organic compounds) Chemical Agent Resistant Coating (CARC) using the carbon dioxide process. This complements the waterborne program that is already well into the development phase. The carbon dioxide process not only allows lower VOC coatings to be used, but the decompressive atomization results in improved transfer efficiency, which benefits both overall emissions and potentially the economics of the paint application process. The reduced VOC coating applied using the carbon dioxide process program is in the trial phase and large components have been painted successfully in production facilities.
