Fuzzy Logic as a Tool to Compare Reliability of Torsion Bar System

Abstract

Abstract : One of most critical systems in military vehicles is the suspension system and the reliability of the system is essential to maintain a mission capable status. When changes to the vehicle suspension system are warranted, the reliability of the system must be reevaluated to assure that service life is maintained. As the design to implementation cycles continue to be reduced, new tools are needed to be developed to aid in the decision making process. The purpose of the paper is to demonstrate the use of fuzzy logic programming in the prediction of reliability early in the design process. In order to achieve this goal, this paper will evaluate a simple torsion bar system/road arm system to demonstrate the use of Fuzzy logic. By combining known failure issues on various systems, we will demonstrate the capability of the fuzzy logic program and how it will aid in making design decisions to improve the overall performance of the system.
