The CTC Technology Centre continues to consolidate its position as a centre of excellence in the development and transfer of knowledge on digital twins in the industrial field. In the second follow-up meeting of the Miraged project, the team of researchers from the only technology centre in Cantabria explained their progress both in the identification of structures and mechanical components in different sectors where this technology could be applied and in developing algorithms for real-time knowledge of the state of the element being inspected.
The COVID19 pandemic has forced all members of the consortium to redefine the format of their meetings, conferences and training. Thus, representatives of IDEKO, IDONIAL, IKERLAN, CEIT and CTC updated this initiative by video conference. The first collective control of the project, whose priority objective is to improve the training in this area of the research groups of the five technological centres involved, certified that MIRAGED is progressing with no significant deviations from the established roadmap.
Verónica González de Lena and Aratz García Llona, manager and project manager of the Industry and Energy area of CTC, detailed how, in the characterisation phase, the main degradation phenomena that can affect industrial structures and components are being identified. Thus, aspects such as the incidence of wear, corrosion or fatigue fracture are being analysed to control the elements studied.
Also, in terms of algorithm development, CTC spokespersons indicated that they are working with model order reduction (MOR) techniques to reduce computational costs. Thanks to machine learning and matrix decomposition, this methodology makes it possible to monitor elements in real-time, significantly reducing the number of operations to be carried out.
In the coming months, work will be done on numerical modelling of the various degradation phenomena using finite element models (FEM). The calibration of these constituent models will allow simulating the behaviour of the elements and structures in limit situations such as failure. MOR techniques will also be applied to more complex cases.
The next project monitoring meeting will take place in December, coinciding with the first annual project. In addition to the review of the developments, a small training session is planned, which will be given by the representatives of Ikerlan, the project coordinator. Miraged is part of the Call for the Accreditation Procedure and granting of aid to “Cervera” Technology Centres of Excellence for the year 2019 (CER-20191001). Its main objectives are to foster leadership and collaboration in the industrial field, to promote specialisation in the priority technologies of the Cervera Network and to improve the impact on the Spanish economy.
