Available in PDF, EPUB and Kindle. Book excerpt: With small mobile vehicles, even robots, becoming increasingly important for military operations, Cold Regions Research and Engineering Laboratory (CRREL) researchers set out to instrument an all-terrain vehicle (ATV) with mobility sensors to obtain and understand small-vehicle mobility data in all seasons. Extensive mobility research has already been performed at CRREL on the CRREL Instrumented Vehicle (CIV), which collects mobility data with large and expensive vehicle performance sensors. However, a small vehicle such as an ATV is not suited to carry large data collection instruments. In an effort to overcome cost and size limitations while maintaining functionality, an ATV was instrumented with lowcost sensors to collect mobility data comparable to the CIV. At the U.S. Army's Ethan Allen Firing Range, ATV mobility performance tests, such as coast down and drawbar tests, were performed alongside the CIV for comparison, while cross range test runs were performed to demonstrate the system's capabilities. This paper presents one option for researchers looking to instrument a small-vehicle with mobility performance sensors, describes the testing methodology and results, and offers a comparison to the CIV. Low-cost, portable vehicle mobility instrumentation systems would allow for accurate vehicle simulations and mobility awareness that can be used in situ by the warfighter and lead to further applications of all-terrain vehicles in force protection and border patrol scenarios.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital Image Correlation (DIC) technology developed for off-road vehicle dynamics at the University of Pretoria,South Africa, was recently assessed for all-season and all-terrain viability through a Foreign Technology Assessment Support (FTAS) program at the US Army, Cold Regions Research and Engineering Laboratory in Hanover, New Hampshire. Advancements in camera technology and computational power has allowed algorithms to determine featureand depth tracking of surfaces in sequential images at near real time. These advancements have enabled the application of DIC to measure surface and velocity profiles as well as deformation from a reference state for terrain or for tires. In large off-road vehicle dynamics DIC can be used to assess and validate the terramechanics models by monitoring the road or terrain surface before and after the tire along with the motion of the vehicle or tire; and, when used as real-time feedback with driver assists or control software, to improve maneuverability of vehicles. From these measurements the terrain roughness and deformation can provide terrain trafficability, and the relative terrain and tire motion used for vehicle safety systems.The project objectives were to evaluate the application of DIC on military vehicles to measure deformation and vehicle motion on variable terrain surfaces with the ultimate goal of providing additional information to the driver, vehicle control system, or real-time data assimilation for mobility and maneuver optimization. The technology was tested and validated using the CRREL Instrumented Vehicle, an instrumented HMMWV (M1097) , and the much larger Heavy Expanded Mobility Tactical Truck (HEMTT). Validation testing was conducted using a variety of maneuvers on snow,ice, water, asphalt, concrete and vegetated ground surfaces.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the analysis of off-road vehicle dynamics from kinetics and kinematics perspectives and the performance of vehicle traversing over rough and irregular terrain. The authors consider the wheel performance, soil-tire interactions and their interface, tractive performance of the vehicle, ride comfort, stability over maneuvering, transient and steady state conditions of the vehicle traversing, modeling the aforementioned aspects and optimization from energetic and vehicle mobility perspectives. This book brings novel figures for the transient dynamics and original wheel terrain dynamics at on-the-go condition.

Available in PDF, EPUB and Kindle. Book excerpt: The reported study is part of a broad research program designed to acquire off-road mobility knowledge; develop analysis, prediction, and decision methodologies; and organize knowledge and methods to facilitate use by military planners, vehicle designers and field personnel concerned with off-road mobility. This particular study was concerned with the development of generalized vehicle-terrain mathematical models of wheeled and tracked vehicles running in hard and soft soil. The computer simulation phase of work was carried to the point of mechanizing 3-degree-of-freedom and 5-degree-of-freedom models in real time on the analog computer. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Driving safety and ride comfort of cross-country vehicles can be improved with the help of a controlled spring/suspension system. The present paper describes the impact of a semiactive and partially active chassis system on the driving behaviour of a cross-country 8x8 wheeled vehicle. The mobility analysis is based on a multibody vehicle model used for simulating cross-country drives and handling. To start with, the fundamental Skyhook"--Principle is used for controlling; vertical accelerations and vehicle movements are clearly reduced on rough tracks and sine wave lanes.
