摘要
文章主要推导了可用于描述大型降落伞绳帆和抽打现象的一般绳索三维动力学连续模型,及弦坐标系下可用于求解绳帆现象的两点边值问题(BVP)模型,并采用某型号大型降落伞的空投录像和杆件算例对模型进行验证对比,说明了模型的正确性,采用这一连续模型能够更直观地对大型伞的绳帆和抽打现象进行定性和定量分析。
The rope continuous dynamic models for large parachute's linesail and bullwhip were discussed in this paper.A simple pole example was used for the validation of the bullwhip dynamic model,and a flight test video got from a large parachute recovery system was used for the validation of linesail model.The well matched results demonstrated that the models were suitable for the qualitative and quantitative analysis of large parachute's linesail and bullwhip.
