Abstract

The invention discloses a railway freight train operation safety assessment method and system, and the method comprises the steps: firstly, calculating the mass, t, the centroid position and the rotational inertia parameters of each carriage after loading goods according to the data collected by a data collection device arranged on each carriage; T; then, t, the mass of each carriage is adjusted after the cargos are loaded; i; inputting the centroid position and the rotational inertia parameters into the built dynamic model of the corresponding freight train; T; the method comprises the stepsthat firstly, t, the dynamic response of each carriage is calculated, corresponding safety indexes are calculated according to the dynamic response of each carriage, t, then whether the safety indexesof the carriages meet the safety operation condition or not is judged, and only if the safety indexes of the carriages do not meet the safety condition, it is considered that the safety indexes of the freight train are unqualified. Therefore, whether the safety index of the multi-section marshalling freight train loaded with the goods is qualified or not can be accurately and effectively evaluated, and therefore potential serious accidents such as derailment are avoided.

Description

technical field [0001] The invention relates to the technical field of railway transportation safety, in particular to a method and system for assessing the operation safety of railway freight trains. Background technique [0002] The safety of railway transportation is the top priority in the field of rail transportation. With the significant increase in the speed and load of freight trains, the safety of freight trains has become the focus of attention. [0003] At present, the monitoring of the running status of traditional freight trains mainly adopts the monitoring method of overweight and overrun. Usually, the data module transmits the received information to the monitoring module, and then sends a signal to the alarm module through the monitoring module to realize the alarm. However, the monitoring method of overweight and overrun can only effectively monitor the running state of a single-section freight train. However, the multi-section high-speed freight train adop...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to propose a method for assessing the safety of railway freight train operation in view of the problems that multi-section freight trains are prone to unreasonable distribution of cargo loading and may cause potential serious accidents such as derailment due to excessive longitudinal impact , it can evaluate whether the distribution of cargo loading in multi-carriage freight trains meets the requirements of operational safety, so as to avoid potential serious accidents such as derailment caused by excessive longitudinal impact due to unreasonable distribution of cargo between cars
