This paper proposes a novel analysis methodology applying bond graph (BG) theory for dynamic systems prognostics, which is realized through the derivation of a mathematical model from physical knowledge using the BG formalism. The graphical formalism allows generating residuals to derive the system degradation model. Moreover, the performance threshold can be determined by stability analysis to predict remain useful life of degraded components. The efficiency of the proposed methodology was demonstrated through a simulation experiment for locomotive electronically controlled pneumatic brake. A leakage fault of relay valve is injected and then predicted. The experimental results show that well performance can be obtained with lower uncertainty, which make the prognostics analysis suitable for engineering application in short of sufficient historic data.
