Bond graph modeling and fault injection of CRH5 traction system

Methodology for Model Architecting and Failure Simulation Supported by Bond-Graphs—Application to Helicopter Axial Piston Pump

“…When considering simulation models developed to enable the effect of degradation on the physical outputs of a system to be studied, it is of interest to simulate temporal variations of faults. Some authors, e.g., [13], discuss the matter in the literature, but never from the point of view of implementation. On the basis of this status, the authors have introduced in the proposed methodology an approach that takes advantage of the Bond-Graph formalism to support the fault injection and the simulation of the response to the fault.…”

“…Only a few published papers deal with architected lumped-parameter models. They ignore or poorly address architecting or structuration methodology, e.g., [13], [14] or [15]. In [16], the authors define an electro mechanical actuator model architecture derived from the product topology.…”

“…In the current approach, BGs are used as a tool to support the development of models to simulate failures so as to define the proper physical quantities to be monitored. One example of the use of BGs in such a context of failure simulation and fault injection can be found in [13], where the authors simulate the temporal deterioration of the traction system of the Chinese high speed train. However, although they disclose the degradation models used, they do not address the methodology used for fault injection.…”
