摘要
以某项目研制过程中,减速伞提前分离故障为切入点,探讨了吊带在非正常位置受力导致的吊带断裂问题。根据相关视频资料及落地现场的检查情况,以及采集到的测试数据,对故障机理进行了全面分析,并结合减速伞下吊带静态拉伸试验及动态冲击试验结果,借鉴国内外吊带系统的相关设计经验,提出了从工作程序、结构及强度3方面采取措施,解决吊带在非正常位置受力导致的吊带断裂问题。
A sever problem that the parachute separates in advance can impede a successful rocket recovering.This paper analyzes the advanced separation and targets broken slings that function in abnormal positions un⁃der parachutes.We inspected the separation fault in field,and gleaned video and test data.Then,we conduct⁃ed a simulated experiment on the parachute sling under both static tension and dynamic impact conditions,and identified the causes of the broken sling.The results inspired us to develop a scheme to prevent slings from breaking,including three measures from the perspectives of working procedure,structure and strength.
