FTTS Powered Trailer - A Systems Approach.

摘要

This paper summarizes the results of work accomplished jointly by SEI and TARDEC/NAC on the Powered Trailer Technology CRADA program (CRADA No. 04-02) A systems approach for identifying FTTS powered trailer requirements and technologies is presented along with results of a Quality Function Deployment (QFD) analysis of the Maneuver Sustainment Vehicle (MSV) trailer requirements and applicable technology solutions. The QFD analysis was useful for prioritizing requirements and assessing technologies based on performance, cost and risk. Tradeoff evaluations among trailer power drive concepts are presented. These include Electric Drive, Hybrid Electric Drive, Hybrid Hydraulic Drive Mechanical Power Take Off, and Internal Combustion Engine (ICE) Drive. System Block Diagrams and performance summaries (mobility assist performance, weight, interoperability design complexity. etc.) were generated to illustrate the advantages and disadvantages of each concept. ProE CAD models have been used to illustrate potential design layouts packaging issues, and interfaces. Results of the coupled transport/trailer vehicle mobility analysis are provided to highlight the benefits of trailer mobility assistance under real world operational conditions.
