Embodiment Construction
[0009] It uses the principle of similarity to design and manufacture the vibration table, and then monitors acceleration, displacement, earth pressure, etc. by inputting seismic waves and laying out test components, and uses high-speed binocular imaging equipment to monitor the phenomenon of train derailment, and finally obtains Threshold value of train derailment under high-speed railway earthquake. Reveal the influence of earthquake intensity on the safety indicators of high-speed trains on different structures.

The invention discloses a dynamic testing simulated analysis platform of a high-speed railway earthquake early warning system. As a high-speed railway model is designed and manufactured by utilizing asimilarity principle, and a high-definition binocular imaging device is used for monitoring bridges ballastless track roadbeds and ballast track roadbeds, derail threshold values of a running train on different structural materials can be obtained. The dynamic testing simulated analysis platform of the high-speed railway earthquake early warning system has advanced devices and instruments, has exact measured data, is convenient and easy to operate, can obtain derail threshold values efficiently through train derail phenomena.
Description
technical field [0001] The invention relates to a dynamic test simulation analysis platform for a high-speed railway earthquake early warning system, which belongs to the field of test technology. Background technique [0002] Earthquakes are an important hidden danger to the safety of high-speed railway operations. Japan, France, Germany, South Korea, and Taiwan, China, where high-speed railways are more developed, have established earthquake monitoring and emergency response systems to prevent or reduce the impact of earthquake disasters on railway transportation safety. . Due to the complex geology and diverse environment of our country, the existing foreign seismic monitoring systems cannot be fully applied to our country, so it is imperative to study the derailment threshold of different structures under the action of earthquakes. Contents of the invention [0003] Based on the research status at home and abroad, the present invention discloses a set of dynamic simul...
