Download or read book Terrain Validation and Enhancements for a Virtual Proving Ground written by and published by . This book was released on 2003 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently engineers and scientists from the Ground Vehicle Simulation Laboratory (GVSL) located at the U.S. Army Tank-Automotive Research, Development and Engineering Center's (TARDEC) National Automotive Center (NAC) have validated a virtual graphical terrain for use in the real-time warfighter/hardware-in-the-loop motion base simulators. This was accomplished by comparing and analyzing the profile data acquired from the virtual environment of Aberdeen Proving Ground's (APG) Churchville B course with the real data collected over the actual course. To obtain the data from the virtual terrain, complex mathematical equations developed by scientists at GVSL were utilized. The MATLAB analysis tool was used to analyze the data and help verify the terrain. The paper will discuss the processes that we incorporated to validate the database, new techniques being developed to improve our validation and methodologies to give the virtual terrain higher frequency terrain characteristics. Verification of the virtual terrain is important since engineers need to confirm that the profile of the terrain that they are driving the Ride Motion Simulator over corresponds to the real terrain.
Download or read book The TARDEC Story written by Jean M. Dasch and published by Government Printing Office. This book was released on 2013-12-11 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full of illustrations and photographs, this publication is a comprehensive history of the many innovations in tanks and other military ground vehicles and equipment developed by the engineers at TARDEC, the U.S. Army Tank Automotive Research, Development and Engineering Center. TARDEC was formed in 1946 as an outgrowth of the Detroit Arsenal Tank Plant built during World War II. During the early years, emphasis was placed on evolving new technologies to improve military ground vehicles, culminating in the development of the M1 Abrams tank. Since then, TARDEC has grown to be a key center for advanced technologies for military ground vehicles and equipment. Recent years have brought an explosion of technology development and integration, from hybrid engines to fuel cells, from analytical simulation to enormous physical simulators, and from small robots to entire unmanned vehicles.
Download or read book Terrain Severity Data Generation at Yuma Proving Ground written by and published by . This book was released on 1990 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report details results of a course profiling exercise conducted at the Yuma Proving Grounds (YPG) Arizona using the Nevada Automotive Test Center (NATC) Dynamic Force Measurement Vehicle (DFMV) methodology and the Aberdeen Proving Grounds (APG) inertial profilometer methodology. The rod and level methodology was used to establish the baseline for validation and comparison purposes. Eleven test courses were profiled at YPG. The test course profiled included terrain representative of that used by the Army for ground- based vehicle durability testing. All data acquired was supplied to the U.S. Army Tank-Automotive Command (TACOM) for further analysis by their simulation department. For each of the eleven courses, a left- and right-wheel path elevation versus distance profile, a left- and right-wheel path wave-number spectrum and coherence function plots were computed from the four wheels on the DFMV. This data was compared to equal data from the rod and level and the inertial profilometer. Volume II contains the data for the different DFMV speeds over each YPG course.

Available in PDF, EPUB and Kindle. Book excerpt: This report details the results of a course profiling exercise conducted at the Yuma Proving Grounds (YPG), Arizona, using the Nevada Automotive Test Center (NATC) Dynamic Force Measurement Vehicle (DFMV) methodology, the U.S. Army Waterways Experiment Station (WES) rod and level method and the Aberdeen Proving Ground (APG) inertial profilometer method. The rod and level method was used to establish the baseline for validation and comparison purposes. Eleven test courses were profiled at YPG. The test courses profiled included terrain representative of that used by the Army for ground- based vehicle durability testing. All data acquired was supplied to the U.S. Army Tank-Automotive Command for further analysis by their vehicle simulation department. For each of the eleven courses, a left- and right-wheel path elevation versus distance profile, a left- and right-wheel path wave-number spectrum and coherence function plots were computed for the four wheels on the DFMV. This data was compared to equal data from the rod and level and the inertial profilometer. Based upon the profiles and wave-number spectra computed using procedures in this report, techniques for measuring and monitoring road roughness characteristics are recommended. It is further recommended that a wave-number spectrum course roughness description replace the current RMS roughness index.

Download or read book Virtual Environments for Dismounted Soldier Simulation Training and Mission Rehearsal written by Bruce W. Knerr and published by . This book was released on 2002 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report describes the activities and results of the third year culminating event (CE) of the 'Virtual Environments for Dismounted Soldier Simulation, Training and Mission Rehearsal' Science and Technology Objective (STO). This STO is being conducted jointly by the U.S. Army Research Institute for the Behavioral and Social Sciences, the U.S. Army Simulation, Training, and Instrumentation Command (STRICOM), and the U.S. Army Research Laboratory. This four-year effort (FY99-FY02) is focused on overcoming critical technological challenges that currently prevent high fidelity dismounted soldier simulation. The objectives of the CE were to integrate and evaluate the technologies developed during the year. The key technologies included: a Dismounted Infantry Virtual After Action Review (AAR) System; new behaviors and improved operator control for Dismounted Infantry Semi-Automated Forces (DISAF); soldier control of DISAF through Voice Recognition and Synthesis; enhancements to the soldier simulator, the Soldier Visualization Station (SVS); an improved locomotion device, the Omni-Directional Treadmill (ODT); a dynamic terrain server; and a Mission Planning and Training Tool (MPTT). The CE provided a realistic and challenging test of the systems and capabilities under development. The results identified both accomplishments and areas in which improvements and corrections are required."--Report documentation page.
Download or read book Statistics Testing and Defense Acquisition written by National Research Council and published by National Academies Press. This book was released on 1998-05-08 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: For every weapons system being developed, the U.S. Department of Defense (DOD) must make a critical decision: Should the system go forward to full-scale production? The answer to that question may involve not only tens of billions of dollars but also the nation's security and military capabilities. In the milestone process used by DOD to answer the basic acquisition question, one component near the end of the process is operational testing, to determine if a system meets the requirements for effectiveness and suitability in realistic battlefield settings. Problems discovered at this stage can cause significant production delays and can necessitate costly system redesign. This book examines the milestone process, as well as the DOD's entire approach to testing and evaluating defense systems. It brings to the topic of defense acquisition the application of scientific statistical principles and practices.
