Technical Approach for Coupled Reliability-Durability Assessment of Army Vehicle Sub-Assemblies

Abstract

The US Army is seeking to advance simulation methods for assessing the performance and reliability of ground vehicles. The reliability is defined as the probability that the Army vehicle performs its function over a specified period of time and under specified loading conditions; it can be viewed as a measure of successful performance of the component, sub-assembly and eventually whole vehicle. For the structural reliability calculation to be meaningful, it must be coupled with durability evaluation. The durability describes the ability of the structure to endure or resist applied loading. Maximum benefit would be obtained when both the reliability and durability are maximized. Such an outcome is highly desired, especially if it is achieved at low cost and low weight.
