INSE RAIL AND TELICE, WITH THE SUPPORT OF THE CDTI, HAVE DEVELOPED THE HAMMER PROJECT, A SYSTEM FOR MONITORING THE STRUCTURAL INTEGRITY OF RAILWAY INFRASTRUCTURE BY ANALYZING ITS DYNAMIC RESPONSE.
Hammer also included participation by two main collaborators, the Fundación Caminos de Hierro and ANCO Engineers Inc.
Four situations have been identified in which this system represents significant added value:
Dynamic load testing for commissioning of new structures in accordance with standards.
Specific inspections of structures that are in service when damage has been detected and/or on lines on which a dynamic load increase is expected.
Analysis of the degree of deterioration of a structure over time, applicable to preventive maintenance of structures.
R&D&I activities and its application in predictive maintenance
The spectrum of target clients is made up of infrastructure management companies, construction companies, and railway operators that are also responsible for maintaining the network, as well as companies specializing in asset management.
The project culminated with the tests carried out in León (02/18), under the institutional auspices of ADIF, whose permission to access to the two structures that were tested was key.
The tests were performed under very adverse conditions: the test of the first bridge coincided with the largest snowfall of the winter, and the second was performed at night under heavy rainfall. The results obtained have validated the industrial technology developed and the method designed to characterize the condition of railway structures.
The next step is to expand the functions of the system and begin marketing it through HAMERTEC, after the process of patenting the product has been initiated.
