水声对抗子母弹抛撒过程结构强度仿真

The Structural Strength Simulation of Dispersal Process of Water Acoustic Confrontation Cluster Bombs

为了验证子母弹发射舱内峰值压力对抛撒过程的可靠性,在子母弹活塞式抛撒内弹道模型的基础上,应用LS-DYNA对抛撒部件结构强度进行数值模拟,得出了在装药等量增加时的压力变化规律及抛撒机构动力冲击响应,分析论证了部件强度失效模式,并对稳定性差的部件,给出了可行性设计方案。

In order to verify that the peak pressure in cluster bombs cabin affecting the reliability of spreading process, based on the dis- persal interior ballistics model of the cluster bombs dual piston combustion , the strength of critical components of the dispersal structure was emulated by LS-DYNA. When the charge mount increased, the changes rule of pressure cabin and impulse response of the separation mechanism were obtained The failure mode of the components strength was analyzed and the feasibility of the design scheme for components with poor stability was demonstrated.
