【Abstract】 In this paper, the fundamental problems in the calculation of transverse vibration of train bridge and train track time varying system are expounded. Our thought and our approach to these problems are introduced. The theory of energy random analysis for train derailment is presented. Using this theory, authors have forecast the actual freight train derailment, which is in conformity with the actually accident occurred. They also have identified another experimental freight train being not derailed, and calculated its maximum vibration responses. Our calculation results are very close to those obtained from the field test.更多还原
