Abstract: The emergency recovery simulation vehicles integrated tamping, stabilization and measurement devices were developed by finite element analysis. Through the analyses under ten working conditions, the rigidity and strength of the car bodys may meet the requirements and the load distributions are reasonable. During the development processes some technical challenges such as whole machine layout, multiple working devices sharing the one car body, repeated derailment and recovery were solved. The simulation vehicles might provide training for rail and infrastructure maintenances, as well as fault simulation of emergency repairs for the large-scale track maintenance machines and functional simulation of rapid off-track and recovery, which might train rail maintenance and emergency rescue personnels economically, effectively with high quality. It is ensured that the whole processes of entry, construction and evacuation of large-scale track maintenance machines are completed within the “skylight” blockade time when the line is busy.
