Abstract: This paper describes a computer-based modelling, simulation and validation effort to aid in the development, testing and procurement of a lightweight, High Mobility Trailer (HMT) towed by the High Mobility Multipurpose Wheeled Vehicle (HMMWV). The US Army is acquiring an HMT capable of performing strategic operations in various climates and environments while hauling payloads up to 1140 kg. A series of field tests and analytical studies were conducted to evaluate candidate trailers. This study employed computer-based modelling and simulation to determine the upper bounds of vehicle performance under various adverse operating conditions, and parameter and design sensitivity studies to identify more stable system configurations. This paper reports on the modelling, simulation, validation and analysis of a HMMWV towing multiple-configuration HMT|s.

Keywords: computer-based analysis; high mobility multipurpose wheeled vehicles; HMMWV; high mobility trailers; HMT; on-road performance; off-road performance; system stability; simulation; modelling; validation; towing; truck-trailer systems.
