轨道救援车辆作为轨道交通事故救援中的重要设备,需要应对复杂而多变的环境。通过分析轨道交通事故及环境状况特点,确定改进设计的方向。运用模块化设计方法,拆分并重构了轨道救援车辆的各功能模块,对各个功能模块进行了改进设计,给出了最终设计方案,为我国轨道救援车辆的自主研发提供参考。 As an important equipment in the rescue of orbital accidents, orbital rescue vehicles need to deal with complex and ever-changing environment. By analyzing the characteristics of rail accidents and environmental conditions, determine the direction of improving the design. The modular design method was used to split and reconstruct the various functional modules of the orbital rescue vehicle and to improve the design of each functional module. Finally, the final design was given to provide a reference for the independent research and development of China’s orbiting rescue vehicles.
