This presentation addresses key aspects of the ground vehicle reliability prediction. The focus of this session is on the enhancement of the overall vehicle reliability prediction process of all available sources of information, physics-based models, test databases and expert knowledge. The integrated reliability prediction approach incorporates the following computational steps: i) simulation of stochastic operational environment, ii) vehicle multibody dynamics analysis, iii) stress prediction in subsystems and components, iv) stochastic progressive damage analysis, and v) component life prediction, including the effects of scheduled maintenance and, finally, iv) reliability prediction at component and system level. This presentation illustrates the application of the integrated reliability prediction framework to the reliability prediction of the HMMWV front suspension system.

Innovative technology to optimize military vehicles This master class will cover conceptual design and optimization of the fan aboard the USMC Expeditionary Fighting Vehicle (EFV). The goal of the design is to maintain or improve the performance of the current fan while reducing the acoustical noise that is being produced. A comprehensive design and optimization procedure was undertaken that coupled CFD, FEA, and a turbo-machinery acoustical noise analysis code. The resultant design has provided substantial noise reduction at high levels of aerodynamic efficiency, while maintaining mechanical integrity.

This workshop will cover the development of a processing methodology for improving strength and corrosion resistance properties of carburizing stainless steel (CSS-42L) through surface carburization prior to aging and heat treatment. CSS-42L will be evaluated by various modifications to the tempering and quenching temperatures. Examples of analytical and modeling tools will demonstrate the surface modification process parameters such as hardness and residual stress through thickness.

Learn about a technology that detects damage to critical suspension components in military vehicles simply by driving over a speed bump-like "diagnostic cleat" containing sensors. The aim of this technology is to save time and maintenance costs by catching damage before it leads to failure in the field. This system measures vibrations created by forces that a vehicle's tires apply to the cleat. Damage is detected in the tires, wheel bearings, and suspension components by using signal processing software to interpret the sensor data. By using the instrumented cleat and other "condition-based" maintenance methods, the military could reduce costs by performing work on vehicles when needed based on the condition of parts instead of performing scheduled maintenance on vehicles regardless of whether they need the work.
