Title:Alternative Materials for Tactical Vehicle Wheeled Hubs
Abstract:More than 8900 MTVR’s are in service with the Marine Corps and with its proven off road performance and survivable armor package, the MTVR continues to be heavily used in theater for logistics and other missions. The MTVR currently uses mild to medium strength steel or ductile iron components in the TAK-4 suspension, which have not been optimized for weight. Reducing the weight of the un-sprung axle components would improve the vehicle handling, increase vehicle payload and improve fuel economy. GS Engineering proposes several concepts using existing technology to lightweight the wheel end of the MTVR. Target candidates include the hub, wheel and planet carrier housing. Using existing proven light weighting materials such as forged and cast aluminum and austempered ductile iron, these components present a significant light weighting opportunity of approximately 800 lbs for the full vehicle, which is a 48% weight savings of the replaced components. Improvements to the current Central Tire Inflation System (CTIS) design at the wheel ends will be further investigated for additional weight reduction opportunities. GS Engineering has enlisted the expertise of Hutchinson Industries, an industry leader in lightweight wheel solutions to assist this effort.

Title:Alternative Materials for Tactical Vehicle Wheeled Hubs
Abstract:KaZaK Technologies and our program subcontractors and technical associates are proposing several concepts to reduce Medium Tactical Vehicle Replacement (MTVR) wheel hub weight to increase cargo capacity and improve vehicle handling. An increase in cargo capacity provides the MTVR to be outfitted with the MAS up armor protection minimizing impacts to vehicle performance. One obvious approach to reducing wheel assembly weight is to change materials used to make wheel components from its current steel construction to a much lighter fiber reinforced composite system. Cost reductions are possible by careful selection of the manufacturing process as well as by reducing/automating assembly. During Phase I, our team will develop concepts and refine sub-component material handling/assembly systems and integration with automated in-line production/assembly processes. If awarded a Phase II, our team will work to apply Phase I automated process manufacturing technology to the fabrication and assembly of a prototype low cost MTVR wheel assembly for qualification testing.

Title:Adaptive Diesel Engine Control Via Variable Valve Timing
Abstract:Diesel engines are widely used in military and commercial vehicles, as well as some light duty vehicles. The compression ratio is a compromise between power, economy, and cold startability. The optimum ratio for economy is below 15:1, whereas the necessary compression ratio for cold starting ranges from 16 to 22:1 depending on the specific engine design. This is too high for best economy and optimum boost. The proposal objective is to demonstrate a combination of simple mechanisms designed for the Caterpillar C-12 to improve fuel economy particularly during idle as well as improve engine power output. The technology will include varying the compression ratio between high (for cold starting) and low (for warmed-up running). Minimal or no engine block modifications are anticipated. The work proposed is to demonstrate hardware viability in a bench test rig as well as estimate/model fuel economy and power improvement from the proposed technology. For the SBIR OPTION, a system will be installed on one cylinder of a multi-cylinder engine and motoring tests run to demonstrate effectiveness.

Title:Adaptive Diesel Engine Control
Abstract:LaunchPoint Technologies proposes to adapt their patented electromagnetic valve actuator (EVA) to the C12 engine in the MTVR cargo vehicle. The actuator will allow the implementation of variable valve timing and cylinder deactivation functionality on the engine, which will result in increased engine efficiency at variable and part-loads; as well as increased maximum torque and power output. In phase I LaunchPoint Technologies will simulate engine performance to determine achievable efficiency and power gains. LaunchPoint will also do preliminary designs of actuators designed specifically for the C12 application along with the power and control system. LaunchPoint Technologies will analyze the resulting system performance. LaunchPoint Technologies’ patented EVA can achieve more precise control and lower valve seating velocities than the competitors while remaining cost effective to implement in a commercial application. The actuator also achieves high switching speeds while minimizing electrical power consumed.

Title:Continuous Estimation of CG, Inertial and Loading
Abstract:Archangel Systems, Inc. proposes a feasibility study of a technical and forward-thinking solution for optimized vehicle loading: the Continuous Estimation of CG, Inertial and Loading CECIL). The investigation considers the needed caliber and optimum distribution of inertial and load sensors and the quantifying modal analysis algorithm options for continuous monitoring of CG and load. Inertial sensor(s) with and without the addition of load sensors are simulated using a full vehicle model to monitor vehicle weight and dynamics both during the loading process and during operation. Simulated measurements and algorithms extracts total load, load distribution, CG in three dimensions, and how all three change throughout the mission. Algorithms use Fast Fourier Transform to detect modal signature changes in vehicle’s dynamics in real time which are mapped to CG shifts and weight changes. This investigation compares optimized conventional methods of load sensors for weight estimation to the proposed inertial method to show a full picture of feasibility. Furthermore, algorithms project the vehicle dynamics forward in time and input the future vehicle state to a 3-D model for the vehicle’s stability along with the CG and loading measures. The model computes future rollover risk and alerts the crew before rollover is imminent.

Title:Novel Sensor System for Real-Time Mapping of a Tactical Vehicle’s Weight and Center of Gravity
Abstract:The United States Marine Corps is seeking a method to reliably monitor a tactical vehicle’s weight and center of gravity (W&CG), real-time, using an integrated on-board system. Such a W&CG mapping system would increase vehicle state awareness providing for optimal performance and safer operation. Also, by monitoring W&CG, a vehicle can be safely loaded up to its optimal payload without exceeding gross weight limits, thereby increasing vehicle/transport efficiency. Mainstream believes that the optimum solution incorporates a novel measurement system to quantify the force applied to each tire. This method of measuring the force, in concert with a proprietary monitoring algorithm, will continuously yield the vehicle weight and, conditionally yield, the CG position. However, in order to pinpoint the vertical CG position, an additional dynamic test may be required. The system will also allow for user-input to dictate load type, in effort to circumvent the need for a dynamic test. The final system output would display the most recent weight and CG component predictions, from the continuously updating system.

Title:Dynamic Vehicle Center-of-Gravity and Gross Weight Estimation Using Readily Available Sensors
Abstract:Poseidon Systems, in collaboration with Rochester Institute of Technology proposes to develop and demonstrate a novel sytem for estimating vehicle gross weight and center-of- gravity location using an innovative nonlinear real-time filter based method. The proposed algorithm uses known physics-based kinematic relationships between vehicle states for the estimation process and requires minimal set of low cost sensors that can be easily integrated into existing vehicle platforms. The physics-based kinematic relationships are used to derive the vehicle’s imposed loading estimates. Once the imposed load is determined the algorithm quickly isolates the vehicle’s gross weight and center-of-gravity. The new real-time filtering algorithm is based on an augmented version of the Sliding Mode Control algorithm which guarantees stable convergence of the vehicle’s gross weight and center-of- gravity estimates. Preliminary simulation studies applied to aircraft systems have demonstrated fast convergence of the aircraft’s gross weight and center-of-gravity location within a high degree of accuracy. Phase I will focus on proof-of-concept software-in-the-loop demonstration, refinement to the current algorithms, and development of the supporting sensing platform. Phase II efforts will bring a fully embedded, field-ready system that will be demonstrated using a relevant military ground vehicle platform for a mission profile.

Title:Low-Cost On-board Weight and Center of Gravity Measurement System for Tactical Ground Vehicles
Abstract:The Medium Tactical Vehicle Replacement (MTVR) is used by the Marine Corps to transport a wide variety of assets. To make the most of each supply mission, these vehicles are filled to optimize space, often resulting in an overloaded vehicle with a dangerously high or offset CG. For this reason, one of the MTVR’s top three technical issues is safety, specifically rollover prevention. The solution proposed herein addresses this need with a low- cost on-board measurement system to provide vehicle weight and CG location while the MTVR is being loaded. These parameters are updated in real-time throughout the mission to capture changing or shifting cargo. The information is presented to the driver in intuitive and meaningful terms such as minimum safe breaking distance and maximum turn rate. It will also provide these critical mass property inputs to the vehicle stability control system.The product development plan is centered on the design of a practicable measurement system and underlying signal processing algorithms. Phase I emphasizes prototype hardware implementation, embedded algorithm and code development, and field experiments with a test vehicle that will lead to early insight into system architectures suitable for deployment in the MTVR and other target platforms.
