A generalized equivalent circuit model for lithium-iron phosphate batteries

Torregrosa, A. J.; Broatch, A.; Olmeda, P.; Agizza, Luca (Elsevier, 2023-12-01)

[EN] Most of the equivalent circuit battery models available in the literature have been developed specifically for one cell and require extensive measurements to calibrate cell electrical parameters in different operating ...
Certification of projection-based reduced order modelling in computational homogenisation by the constitutive relation error

Kerfriden, Pierre; Ródenas, J.J.; Bordas, S.P.-A. (Wiley, 2014-02-10)

In this paper, we propose upper and lower error bounding techniques for reduced order modelling applied to the computational homogenisation of random composites. The upper bound relies on the construction of a reduced model ...
Desarrollo e implementación de un banco de ensayos virtual de aerogeneradores para diferentes regímenes de funcionamiento y condiciones de fallo

Terrón Santiago, Carla (Universitat Politècnica de València, 2022-07-04)

[ES] Las averías inesperadas en las máquinas eléctricas rotativas pueden provocar tiempos de inactividad no programados, que pueden tener como consecuencia grandes pérdidas económicas. Esto aplica a las máquinas eléctricas ...
Induction machine model with finite element accuracy for condition monitoring running in real time using hardware in the loop system

Sapena-Bano, Angel; CHINESTA SORIA, FRANCISCO JOSE; Pineda-Sanchez, Manuel; Aguado-López, Jose Vicente; Borzacchiello, D.; Puche-Panadero, Rubén (Elsevier, 2019-10)

[EN] Most industrial processes are run by induction machines (IMs). Condition monitoring of IM assures their continuity of service, and it may avoid highly costly breakdowns. Among the methods for condition monitoring, ...
Low-Computational-Cost Hybrid FEM-Analytical Induction Machine Model for the Diagnosis of Rotor Eccentricity, Based on Sparse Identification Techniques and Trigonometric Interpolation

Terrón-Santiago, Carla; Martinez-Roman, Javier; Puche-Panadero, Rubén; Sapena-Bano, Angel (MDPI AG, 2021-10-20)

[EN] Since it is not efficient to physically study many machine failures, models of faulty induction machines (IMs) have attracted a rising interest. These models must be accurate enough to include fault effects and must ...
Model reduction based on sparse identification techniques for induction machines: Towards the real time and accuracy-guaranteed simulation of faulty induction machines

Sapena-Bano, Angel; Chinesta, F.; Puche-Panadero, Rubén; Martinez-Roman, Javier; Pineda-Sanchez, Manuel (Elsevier, 2021-02)

[EN] The development of condition monitoring (CM) systems of induction machines (IMs) is essential for the industry because the early fault detection would help engineers to optimise maintenance plans. However, the use of ...
On the limitations of low-rank approximations in contact mechanics problems

K. Sagar Kollepara; Navarro-Jiménez, José-Manuel; Y. Le Guennec; L. Silva; Aguado-López, Jose Vicente (John Wiley & Sons, 2023-01-15)

[EN] Typical strategies for reducing the computational cost of contact mechanics models use low-rank approximations. The underlying hypothesis is the existence of a lowdimensional subspace for the displacement field and a ...
Parametric model for the simulation of the railway catenary system static equilibrium problem

Gregori Verdú, Santiago; Tur Valiente, Manuel; Nadal, E.; Fuenmayor Fernández, Francisco Javier; Chinesta, F. (Elsevier, 2016-08)

Dynamic simulations of pantograph catenary interaction are nowadays essential for improving the performance of railway locomotives, by achieving better current collection at higher speeds and lower wear of thecollecting ...
