Failure analysis and improvement measures of hypervelocity monorail rocket sled
-
摘要:
探讨了国外火箭橇高速运行失稳现象和原因，针对近期超高速单轨火箭橇试验失败现象，从光电经纬仪、遥测、轨道不平顺和靴轨间隙等实测数据方面展开了故障分析，采用橇轨耦合动力学分析方法对故障进行复现，提出了有效解决措施，对系统进行了改进，并进行了试验验证和振动数据对比。结果表明：火箭橇系统在
1100 m/s速度附近发生剧烈共振，导致产品橇舱体在薄弱处发生破坏；靴轨间小间隙加剧了火箭橇在低速条件下的振动，而高速条件下熔融磨损使间隙增加，又加剧了单轨火箭橇滚转扭转效应，导致系统发生局部失效破坏；调整轨道不平顺度、增加产品橇结构强度和刚度、改善靴轨间隙可以有效提升系统运动稳定性。Abstract:To analyze the failure of the recent hypervelocity monorail rocket sled test, the instability phenomenon and causes of foreign high-speed rocket sleds were discussed, and failure analysis was carried out in terms of measured data such as photoelectric theodolite, telemetry equipment, rail irregularity and boot-rail gap. The sled-rail coupling dynamics analysis method was used to reproduce the failure, and effective solution measures were proposed. The system of the rocket sled was optimized and improved. The test verification and vibration data comparison were carried out. The results of the study showed that the rocket sled system resonated violently near the velocity of
1100 m/s, leading to destruction of the sled at weak points. The small gap between the slipper and rail exacerbated the vibration of the rocket sled at low speeds, while melt wear increased the gap at high speeds. This exacerbated the monorail rocket sled roll torsion effect, causing localized failure damage to the system. The system motion stability can be effectively improved by adjusting the rail irregularity, increasing the structural strength and stiffness of the sled, and improving the slipper-rail gap.-
