雷达型空空导弹陶瓷天线罩结构设计与失效分析
|
摘要
雷达型空空导弹研制过程中，天线罩的设计技术是关键技术之一。在某雷达型空空导弹天线罩研制中，其最初方案在地面静热强度试验时，天线罩结构被破坏而导致设计方案失败。本论文通过有限单元法对试验过程进行了模拟，计算结果解释了试验现象。并且通过最初方案的应力有限元计算与分析，找出了结构设计的薄弱环节，为产品的完善设计指明了方向。在接着进行的改进方案天线罩静热强度有限元计算中，不仅得出了与试验结果一致的结论，而且天线罩位移的计算值与试验数据得到了比较好的吻合，验证了有限元计算的精度及其结果的可信性；并且通过对天线罩温度与应力的研究与分析，得出了一些有价值的结论与建议，为导弹天线罩可靠性进一步提高打下了坚实的基础。最后，在前面工作的基础上，提交了一个新型导弹天线罩的结构设计方案，并对该新方案进行了导弹飞行中静热联合载荷作用下的强度分析，结果表明，新方案结构可靠性有了较大的提高，但包括改进方案在内的雨蚀头的连接设计存在一定不足及隐患。本论文的工作，对雷达型空空导弹天线罩型号研制具有一定的参考价值。
The radome design techonic is one of the key techonics in development of a radar-homing air-to-air missile, In development of the radome, the initially designed radome was structurally failed in a ground thermal-structural test. This paper models the failed test by using the finite element method and the results explained the reason of the test failure. By computing and analyzing the stresses on the initially designed radome, the weak point of the radome structure is identified, shedding light on improvement of the radome. In the following finite element computation of thermal-structural strength of an improved designed radome, not only a result consistent with the tests are achieved ,and also obtained displacement of the radome is well meeting the test data, well demonstrating a high accuracy of the finite element method and confidence of its results; And studying on the temperatures and stresses on the radome leads to some valuable conclusions and suggestions to further development, laying a sound foundati
on for further improvement of structural reliability of the radome. Finally, a structural new radome is developed and the new radome is analyzed in strength under structural and thermal loads in missile flight . The results show that the new radome has a much improved structural reliability but with the connection design of the metal tip leaving much to be improved. This paper has a reference value for development of air-to-air missile radomes.
