铁路事故现场数字化建模及动态仿真分析系统

Research and development of three dimensional data acquisition and dynamic simulation analysis system for railway accident scene

为提高传统事故现场调查的效率,便于后期事故分析,借助现代信息技术手段,研究开发一套铁路事故现场数字建模及动态仿真分析系统,主要包含事故数字信息采集、事故场景仿真建模、事故过程分析演练等3个模块,实现了事故现场数字化二维及三维建模、事故过程动态仿真等功能。将系统应用于实际事故案例,验证其有效性和实用性,结果表明:事故过程仿真动画和现场模型除用于铁路事故分析外,还可以用于铁路安全教学培训。

The use of modern information technology can significantly improve the efficiency of the traditional accident scene investigation and provide great convenience for the analysis of late accident,so a railway accident scene digital modeling and dynamic simulation analysis system were developed,including accident data collection,accident scene simulationmodeling and accident analysis and simulation which realized the accident scene data collecting,2 D and 3 D modeling,the accident process dynamic simulating and some other functions. The results show that digital modeling and dynamic simulation can be applied to railway accident analysis and railway safety teaching and training.
