The LOCATE project has finished and with help of all the consortiums members have successfully accomplished the main goals and planned milestones and associated deliverables.
The LOCATE project was able to specify, through discussion with project consortium members, assessment of failure records and application of FMECA, the components to be monitored which have the greatest (positive) impact for Condition Based Maintenance (CBM). It was also possible, based on a preliminary installation of sensors and initial data collection exercise on a locomotive to evaluate and select the technologies to implement in the LOCATE monitoring system. It was also identified the Operational Constraints in a Maintenance Shop to consider on the development of the CBM Framework.
The first measurement campaign was key to support the development and consolidation of the LOCATE, including the sensors set and preliminary validation of the digital twin models.
A demonstrator was installed, and the end-to-end framework validated, including the sensors set, acquisition system, onboard unit and data processing, cloud services for data management and reporting and front-end user interface.
The data analysis showed a good adherence between the measured responses and the digital twin outputs with very promising results.
The exploitation of the main results can be mainly divided into:
-Sensor Set and Monitoring Strategy, which includes the types of sensors and sensors disposition, localization, and installation to provide the means for a bogie monitoring strategy for the different components.
- FMECA Analysis, Analysis of the failure modes and assessment of the impact of the different failure modes.
- Framework of Maintenance Scheduling and Predictive Maintenance Program implementation, Methods of decision making, and scheduling analysis and the tailoring needed for implementing Predictive Maintenance Programs.
- Computational Models and Digital Twin, Design of Computational Experiments based on data collections and Vehicle dynamic simulations for the digital twin modelling.
- Monitoring and Threshold rules Specification, Threshold rules to be used together with the digital model for the component status monitoring.
- Predictive Maintenance Framework, End-to-end framework of the bogie monitoring system in a comprehensive integration and deployment description.
This was performed with involvement of all partners and members of the Advisory Board and FR8Rail III Project, qualifying the project results applicability to a wider range of ECMs.
These product concepts are being exploited, specially by the SMEs partners, by including in their CBM products and service development roadmaps.
