In order to verify that the peak pressure in cluster bombs cabin affecting the reliability of spreading process, based on the dispersal 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.
Key words： cluster bomb; piston model; dispersal reliability; strength simulation
