| 摘 要： | 降落伞开伞过程存在的偏差因素可能会导致开伞动压峰值及开伞力峰值出现极大值,从而对回收过程可靠性造成影响.文章以开伞动压峰值及开伞力峰值为试验指标,采用正交试验方法对比分析了不同水平数情况偏差因素对试验指标的影响度大小,得到了试验指标极值及对应的偏差因素取值条件,并分析了忽略系统初始偏航角、初始滚转角、初始角速度等次要偏... |

| Abstract: | The peak dynamic pressure and the peak opening force,which have important influence on the recovery and landing subsystem’s reliability,would reach their extreme values during the parachute’s inflation process.This paper takes the peak dynamic pressure and the peak opening force as targets,then factors with different levels based on orthogonal experimental method are tested and some important results such as the sensitivity of the factors,the targets’ extremums and the factors’ extreme scheme,are compared with each other,and the result of orthogonal experiment without 7 unimportant factors such as initial yaw angle,initial roll angle and initial angular velocity is also analysed.The research indicates that the results of factors with different levels are consistent with each other in the specified testing conditions |
| Keywords: | Orthogonal experimental method Parachute Inflation process Factor’s level Recovery technology |
