目的 为C型货包90 m/s撞击试验提供新的试验方法和手段。方法 采用基于压缩空气驱动和反向牵引的短距加速技术，以及基于阻尼缓冲缸–迪尼玛绳的短距拦阻技术，建立新型高速重载撞击试验方法，并形成试验装置。结果 实现了负载大于5 t、速度大于90 m/s的大质量试件短距发射和撞击。结论 该试验装置与以往常用于C型货包撞击试验的火箭橇和高空缆绳相比，具有占地少、建设成本低、可调性和重复性好、测试方便、运行经济安全等特点，为C型货包的空运事故场景模拟与考核提供了一种新手段，同时也可为其他类型货包或装备的公路、铁路等运输事故场景模拟与考核提供试验技术支撑。

The work aims to provide a new method for 90 m/s impact test of C-type package. The short-distance launch technique based on compressed air driving and reversed traction and the short-distance arrest technique based on damp buffer cylinder and dyneema rope were applied to establish a new high velocity impact test method for heavy load and form a test facility. The short-distance launch and impact of a large mass specimen with a load more than 5 t and a velocity more than 90 m/s were realized. Compared with rocket sled and high-altitude cable commonly used in C-type package impact test in the past, this test facility has the characteristics of less occupied land, low construction cost, good adjustability and repeatability, convenient testing, economical and safe operation, etc., which provides a new way for simulating air accidents and testing the performance of C-type packages and also supplies a new supporting technique for performance simulation and testing of other types of packages and equipment under other kinds of accidental transportation conditions on roads, railways, etc.
