Computer-aided methods for design evaluation of track systems

A series of computer simulation models for performance and design evaluation of tracked vehicles have emerged in the past decade. In contrast with empirical models developed earlier, they are based on detailed studies of the mechanics of vehicle-terrain interaction, and take into account all major vehicle design features and terrain characteristics. Thus, they provide a comprehensive and realistic tool for the vehicle engineer to optimize vehicle design and for the procurement manager to evaluate competing vehicle candidates. These models have been gaining increasingly wide acceptance in industry and governmental agencies. For instance, the model NTVPM for tracked vehicles with relatively short track pitch has been successfully used to assist vehicle manufacturers in the development of a new generation of high-mobility military vehicles and governmental agencies in the evaluation of vehicle candidates in Europe, North America and Asia.
