Abstract

Breechblock operating force is one of the key test parameters of the shock test bed for gun breechblock system. With the design principle determined, the dynamics principle model of the shock test bed is established based on the virtual prototype technology. The kinetic energy theorem is used to calculate the minimum theoretical force F, a standard value for shock test bed to open breechblock. As both the mass of breechblock operating cam and the breechblock operating distance are fixed, the simulation experiment is performed based on the principle model when the breechblock operating force is F.. The results show that the test bed fails to open breechblock under the working condition for energy loss during the impact. By the research, it is better to grasp the dynamics characteristics of test bed before the physical entity experiments, which is benefit to choose a suitable breechblock operating force.
