Reliability Analysis and Test of Rudder Deployment Mechanism

舵翼展开机构是在弹箭寻求小型化的发射装置以使发射、运输、贮存简单方便的情况下发展起来的。其中舵翼展开机构的可靠性是制约弹箭作战能力的关键因素之一。本研究从舵翼展开机构可靠性研究的国内外状况出发,对各类可靠性指标的理论分析、可靠性仿真及试验的方法流程进行介绍,从而了解当前舵翼可靠性研究的整体进展,然后通过传统可靠性理论、仿真的分析与试验成果,引出了当前舵翼展开机构可靠性分析与试验中存在的一些关键问题。诸如可靠性分析方法的不完善、建模的精确度不高、仿真与试验无法高度契合等。最后就这些问题和不足进行归纳总结,并在此基础上提出一些改善建议及研究热点。进而为舵翼展开机构可靠性中若干研究方向的系统及整体化提供重要的理论意义和应用价值,同时也为其他类似展开机构的可靠性研究奠定基础。

The deployment mechanism of the rudder wing was developed for small-sized launch devices of missiles to make the launch,transportation and storage easy. The reliability of rudder wing deployment mechanism is a key factor for the combat capability of missiles. This paper starts from the domestic and foreign research on the reliability of the rudder wing deployment mechanism and introduces the theoretical analysis,reliability simulation and test method of various reliability indexes to know about the overall progress of the current rudder wing reliability research. Through the above-mentioned traditional reliability theory,simulation analysis and test results,some key problems are put forward on the reliability analysis and experiment of the current rudder wing deployment mechanism. For example,the reliability analysis method is not perfect,the accuracy of modeling is low,and simulation and test cannot be highly fit. Finally,these problems and shortcomings are summarized,and on this basis,some suggestions are put forward,which are of important theoretical and practical value for the system and the integration of several research directions in the reliability of the rudder wing,and they also lay a foundation for the reliability research of other similar deployment mechanism.
