Notes:
The precision diagnosis of subway electric multiple units (EMUs) was conducted withvarious types of engineering analysis techniques for the current performance and wear evaluation.The evaluation was conducted on detailed parts of EMUs, such as car bodies, bogies, brakingsystems, and electrical systems of EMUs. Several characterization means including nondestructiveevaluation techniques, corrosion testing, and three-dimensional measurements, were employed forthe evaluation of car bodies and bogies. For braking system, degradation and performance testswere conducted, while the functional and degradation tests were performed on electrical system inorder to identify the actual performance of the system. Moreover, stress and structural analysesusing commercial finite element method (FEM) software provided important information on stressdistribution and load transfer mechanisms. In this investigation, various advanced engineeringanalysis techniques for the safety analysis of subway EMUs have been introduced and the analysisresults have been used to provide the critical information for the criteria of safety assessment
