LIGHTWEIGHT ENGINEERING OF MILITARY VEHICLES THROUGH REQUIREMENTS ANALYSIS AND FUNCTION INTEGRATION

摘要

The trend toward lighter-weight vehicles in the private sector has been pushed by demands to improve fuel economy, improve dynamic performance, and reduce material and transportation costs. The same demands exist and are even more acute for military vehicles. The reduction of weight across a military vehicle platform can affect hundreds of thousands of vehicles with dramatic ramifications for military budgets, logistic support, deployment time and cost, and other factors critical to national defense. In this paper we report on methods developed for requirements analysis and function integration based on a modeling framework (developed in previous work) which captures requirements, functions, working principles, components, component parameters, test measures, and tests. We also show that the problem of assigning the mass of individual components to requirements is not solvable in practice. The methods are demonstrated using a case study of the United States Department of Defense Family of Medium Tactical Vehicles (FMTV).
