[养护维修装备]采用有限元法的捣固、稳定、测量一体化仿真车设计

运用有限元仿真分析，研发了集捣固、稳定、测量工作装置于一体的应急起复仿真车，通过对10种工况进行分析，以证明车体刚度、强度满足要求，以及受载分布的合理性。研发过程中解决了整机布局、多工作装置共用同一车体以及反复的快速脱轨、起复等技术难题，实现了钢轨和基础设施维修的应用培训，以及大型养路机械应急抢修的故障模拟和快速离轨与起复的功能仿真，能够经济、有效、高质地培养钢轨维修、应急救援人员，并确保线路繁忙时，大型养路机械的进场、施工、撤出全过程在线路“天窗”封锁时间内完成。

Design of Tamping,Stabilization, Measurement Integrated Simulation Vehicles by Using Finite Element Method

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.
