Vehicle Longitudinal Control and Reliability Project. Volume 4. Reliability Enhancement Analysis and Design Test Report.

摘要

The Vehicle Longitudinal Control and Reliability (VLCR) Program is a part of the Automated Guideway Transit (AGT) Technology Program that provides for reliability improvement to be considered a separate task. A summary of reliability enhancement techniques is a part of this task;it is intended to provide a comprehensive body of reliability enhancement information applicable to AGT systems. It is also a step in accomplishing the enhancement of the specific control systems that are being considered in the enhancement of the four generic control system designs. This document is the final report of the Reliability Enhancement Studies for the VLCR Project. It contains the results of the literature search,the development of reliability enhancement techniques,AGT component enhancement,the use of redundancy,enhanced AGT design,and a detailed implementation of selected VLC systems. In this report,techniques for enhancement are listed in terms of their applicability of a system's hardware tier level,beginning with those that are applicable to the component level,to the subsystem level,and to the systems level. The documents annotated in Appendix I (Annotated Bibliography of Applicable Reliability Documents) represent only those which have information directly applicable to the VLCR project. The objective of this Reliability Enhancement Task is to develop techniques to enhance the reliability of VLC systems,and it includes an extensive survey of reliability enhancement techniques previously employed by U.S. Government and Industry programs.
