Propuesta de mejora al plan de mantenimiento de vehículos blindados tipo Cobra II y Ural del Ejército ecuatoriano

Abstract

The purpose of this study is to suggest a technical methodological restructure that is based on the examination of 103 maintenance logbooks, which are genuine historical data, for the Cobra II and Ural vehicles that are used by the Ecuadorian Army. According to the findings of the study, the most of the failures that occurred were in the propulsion, braking, suspension, and transmission systems. The majority of the operations that were performed were corrective maintenance. The information that was gathered allowed for the identification of important factors that enabled the execution of a new maintenance plan that was based on reliability-centered maintenance (RCM) and condition-based maintenance (CBM). Indicators of performance such as operational availability, mean time to repair (MTTR), and mean time between failures (MTBF) are taken into consideration in this new concept. The execution of the strategy that has been presented is based on the use of vehicle hour meters (in line with technical service manuals), and it also incorporates a hierarchical categorization of each important vehicle system. Furthermore, the standardization of new maintenance records is something that is being recommended. The maintenance tasks that are drawn from historical records and ISO standards have been included into this new maintenance plan. The analysis that has been provided reveals that there is the possibility to cut maintenance interventions by twenty percent and corrective maintenance by thirty percent. As a general conclusion, the research indicates a reduction in maintenance times, which translates into greater operational efficiency.
