摘要
为满足某智能弹药的车载状态改型需求,设计集成与弹药平台相匹配的车载发射装置。基于振动分析理论和有限元法,分析发射装置的振动及响应特性。基于有限元法建立了发射装置的有限元分析模型,以弹药的实际发射工况作为计算分析的载荷边界,对发射装置开展了瞬态力学及刚强度分析。基于振动分析理论搭建发射装置的试验系统,通过采集发射过程中发射装置的结构动态响应数据,分析了其振动特性。结果显示,冲击作用下发射装置最大应力位于前安装卡箍过渡圆角处,其最大等效应力为选用材料屈服强度的83.3%,最大变形区域位于后安装卡箍端面处,最大变形量为0.2247mm,表明智能弹药发射装置集成结构设计及选材合理。
In response to the modification requirements of a certain vehicle-mounted smart ammuni-tion,the paper proposes an integrated design of the vehicle-mounted launching system matching the ammunition platform,and analyzes the vibration and response characteristics of the launching device based on vibration analysis theory and the finite element method(FEM),then establishes a finite element analysis model of the launching device based on the finite element method.Taking the actual firing conditions of the ammunition as the load limit for the calculation analysis,transient mechanics and rigidity strength analyses of the launching device are performed.A test system for the launching device is built based on vibration analysis theory.Its vibration characteristics are analyzed by collecting the structural dynamic response data of the launching device during the firing process.The results show that under the launch impact,the maximum stress of the launching device occurs at the transition fillet of the front installation clamp,with the maximum equivalent stress being 83.3%of the yield strength of the selected material.The maximum deformation area is located at the end face of the rear installation clamp,with the maximum deformation amount being 0.2247 mm,indicating that the integrated structural desian and material selection of the smart ammunition launching device are reasonable.
