Confiabilidade e otimização da manutenção em equipamentos: estudo de caso.

Abstract

The present work is motivated by the problem of the implementation of preventive maintenance optimization policies and reliability studies in equipment, there is no subsystem for the activation of the wagon doors of the subway system. All equipment is subject to maintenance, ie repairable equipment which, after failure, can be recovered and resumed from its primary functions. An adequate maintenance plan ensures that the equipment operates at a risk of controlled failure, as well as reducing costly costs with inadequate maintenance policies. Therefore, one objective of this work was a reliability of the equipment, as well as identifying the best time to perform preventive maintenance actions in three equipments, electric motor, pantograph and spindle.The purpose of this work is to evaluate the reliability of all objects of study, as well as to define a maintenance policy and maintenance. In addition, it was possible to establish an average control for the preventive maintenance actions, which constitute an offer of at least 2.7 times in relation to the corrective, or a selection between performing a maintenance without time design and simply letting the equipment, With the values obtained, it was possible to justify the use of the proposed methodology.
