Study on 1D-CAE modeling of air-conditioning for railways and failure prediction using it

Abstract

In order to realize Industry 4.0 and Society 5.0, which create new services and values for social systems, technology that highly integrates the real world and the virtual world is indispensable. However, in the case of equipment for social infrastructure, it is difficult to confirm the actual equipment due to the enormous prototype cost, and simulation using 3D-CAE is also difficult due to the complexity of the product system. Therefore, there are challenges in how to build integrated technology. In this study, we investigated whether the use of 1D-CAE could establish an integrated technology for railways air-conditioner. We also report that the constructed 1D-CAE model is effective for improving the accuracy of failure prediction and estimating the cause of failure.
