Dynamic Factors

When subjected to internal and external dynamic factors, the train wheels move laterally, which can cause a derailment accident. When new external factors are introduced, derailment prevention measures must be established accordingly. For the expansion of railway application, this study aims to develop a fundamental technology for trains to run on the floating bridges on coasts. First, the vibration characteristics of ocean waves were statistically investigated so that simple equations could be proposed for estimating wave heights in terms of frequencies. It was found that ocean waves vibrate at low frequencies. Derailment criteria were derived for wheels on a vibrating track of a floating railway bridge. In addition, results were verified by conducting a shaking table test using a model bogie. A procedure for assessing the running safety of a train on a floating railway bridge subjected to ocean waves was then proposed. Based on this procedure, a model test was performed in a two-dimensional water tank to determine the motion response of the bridge. The running safety of a train on the vibrating track of the bridge was assessed under the influence of actual ocean waves, and measures for safe operation were suggested.

Rail Irregularities

Rail irregularity is the leading cause of enhancing train-track coupling vibration and, therefore, should be studied in detail for safety requirements. In this study, the differences between existing rail irregularities without being subjected to an earthquake between different countries were first studied. Results show that existing power spectrum density and time-domain displacement samples of rail irregularities in the American code are the largest, while the irregularities of the Germany railway are higher than those of China in a specific range of rail wavelengths. Afterward, the effects of earthquake intensity, soil site, and duration on the rail irregularity of a Chinese typical high-speed railway bridge were investigated. For this purpose, a finite element model was established and validated by the shaking table test of a 1/12-scaled high-speed railway bridge experimental specimen. The calculation results indicated that the influences of earthquakes on the rail alignment irregularity were evident.
