Operation of heavy equipment results in the generation of high sound levels. These sounds (exhaust from diesel or turbine engines, clatter of vehicle parts and cargo, movement of joints, etc.), when taken together result in a characteristic acoustic signature. Depending on terrain and environmental conditions this sound may carry several kilometers. This unintentional noise offers an opportunit ...

IN THIS PHASE I EFFORT, THE GOAL IS TO DETERMINE THE FEASIBILITY OF CONDUCTING ACCELERATED CORROSION TESTING OF VEHICLES BY SIMULATING 5-10-15 YEARS OF FIELD LIFE IN A COMPUTER CONTROLLED ENVIRONMENT SIMULATION CHAMBER. THE DIFFERENT REQUIREMENTS OF THE CHAMBER, THE TYPES OF ENVIRONMENTS PRESENT IN THE DIFFERENT GEOGRAPHICAL REGIONS, THE CORRELATION BETWEEN ACCELERATED CHAMBER TESTS AND FIELD COND ...

IN RECENT YEARS THE CORROSIVITY OF THE TACTICAL WHEELED VEHICLE ENVIRONMENT HAS BECOME MORE SEVERE DUE TO INCREASED USE OF ROAD SALTS, INCREASED ATMOSPHERIC POLLUTANTS (SO(2) AND NO(X)), AND CHANGES IN CLIMATIC CONDITIONS IN SELECTED GEOGRAPHIC REGIONS OF THE WORLD. THE COMBINED EFFECTS OF THE ABOVE CONDITIONS AND MARINE SALTS HAVE SIGNIFICANTLY DECREASE THE LIFE EXPECTANCY OF SELECTED VEHICLES AN ...

A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

Military scout vehicles and commercial sports utility vehicles share the common need for advanced suspension/drive systems that offer robustness over widely varying terrain. The ultimate system for handling, ride isolation, and stability control would incorporate high efficiency electric motors independently driving the four wheels, with one on-board high-level computer for controlling the active ...

RAPID INITIATED PROPAGATION (RIP) IGNITORS PROVIDE MORE UNIFORM FLAME SPREADING THROUGH PROPELLANT BEDS THROUGH CYLINDRICAL WAVE EXPANSION ACCOMPANIED BY REDUCED EXPANSION EFFECTS ON THE PRESSURE PULSE. IMPROVEMENTS IN RIP IGNITOR PERFORMANCE ARE POSSIBLE THROUGH: INCREASES IN PRIMER CHARGE DENSITY, REDUCTION IN IGNITOR FREE VOLUME, BLENDS OF IGNITOR MATERIALS, AND USE OF HIGH EMISSIVITY SOLIDS. T ...
