The durability and reliability of military vehicle systems are traditionally tested at Aberdeen Proving Ground by driving vehicles on a set of paved roads, secondary roads, trails, and cross-country terrains. However, driving mile-for-mile over the proving ground test courses is very time-consuming and costly. The U.S. Army Aberdeen Test Center (ATC) has recently conducted accelerated durability tests of wheeled vehicles using two different methods: accelerated hardware-in-the-loop simulation and accelerated field testing. This paper discusses the methods used to date and associated technical details to highlight options for future accelerated testing.
