| Abstract: | This paper introduces the principle of total potential energy with stationary value in elastic system dynamics and the“set in rightposition”rule for formulating matrixes. It also analyses the major problems in the vibration analysis of train-bridge time-varying system and proves the correctness of regarding both the experimental and the randomly simulated hunting waves of vehicle bogie frame as the lateral excitation sources of train-bridge time-varying system. |
