内埋弹舱弹射冲击载荷特性研究
|
摘要
内埋弹舱采用弹射方式投放武器,在弹射瞬间会对上部隔框、进气道等结构产生很大的冲击载荷,需要准确计算内埋弹舱的弹射冲击载荷以供结构设计使用。建立导弹弹射机构动力学模型,通过对舱体结构挂点处分别进行刚性或柔性化处理,得到挂点连接形式对冲击载荷的影响;研究了不同类型作动筒输出的作动力形式和峰值与冲击载荷特性之间关系,分析了弹射架改型设计后挂弹质量对冲击载荷特性的影响。研究结果表明,柔性化连接形式可正确描述冲击载荷的传递过程,且峰值前置的作动力形式提供了更好的弹射效果,挂弹质量与作动力峰值之间关系可指导改型弹射系统的任务包线。
An embedded missile bay launches weapons by ejection. At the moment of ejection,a great impact load is generated on the upper frame and air inlet. The ejection impact loads of embedded missile bay should be accurately calculated for structural design. A dynamic model of missile ejection mechanism is established. The influence of connection form of hanging point on the impact load is obtained through the rigid or flexible treatment of the hanging point of embedded missile bay. The relationship between peak output and impact load characteristics of different actuators is studied. The influence of the mass of a missile on the impact load after retrofitting the ejection frame is analyzed. The research results show that the flexible connection form can correctly describe the transfer process of impact load. And the peak prepower mode can provide better ejection effect. The task envelope of the modified ejection system can be guided from the relationship between the mass of missile and the peak value of power.
