In December 2018, the French Army entrusted Arquus with an experiment on predictive maintenance tools, to be conducted on land equipment: the Evaluation Tactique Vérité (Tactical Evaluation Vérité, Vérité standing for VEhicules Roulants Instrumentés et Tactiquement Employés, instrumented and tactically employed rolling vehicles). The experiment was set with the support of the SIMMT (Structure Intégrée du Maintien en Condition Opérationnelle des Matériels Terrestres, in charge of the maintenance of all French Land equipment).
The goal of EVTA Vérité was to analyze the relevance of predictive maintenance-related technologies and their suitability for the management and use of military fleets. It also aimed at measuring the impact of these technologies on maintenance organization, as well as defining the next development steps.
As part of this tactical evaluation, 20 VAB from the 8e Régiment du Matériel (8e RMAT), were equipped with various HUMS sensors and delivered on June 5, 2019 at the CENTIAL (Centre d’Entraînement Interarmes et du soutien Logistique, Combined Training and Logistics Support Center) in Mourmelon. The instrumentation and data collection protocol had been previously validated on the Satory test tracks in May 2019.
During the collection phase at CENTIAL, between June and December 2019, the VABs were given a wide variety of missions, conducted under very different conditions and on very different terrains. This experiment, carried out in partnership with LGM, was conducted on several thousand kilometers in numerous configurations, thus enabling to build and study a complete database on the spectrum of monitored functions.
SIMMT’s positive feedback on the use of this first data collection highlights the interest of the degradation models created thanks to this study. The analysis of data collected by the sensors enables the construction of complete models to forecast maintenance needs, adapted to the environment and mission profile. Thanks to predictive maintenance, technical failures may be anticipated several days in advance, refining the planning and work of maintenance and logistics personnel of the armed forces.
The generalization of HUMS-based procedures within the land forces should therefore increase the equipment’s uptime. These new approaches should also offer the field commander all necessary tools to properly assess the equipment’s potential and maintenance needs.
The use of HUMS is one of the innovative solutions currently being developed by ARQUUS to improve the maintenance of Army equipment in operational condition. These solutions include the use of 3D printing, as well as virtual and augmented reality.
