弹箱滑移电液随动系统建模仿真与特性研究OA

To mitigate the impact of shock forces on the launch frame and ammunition box during the firing process,an electro-hydraulic servo system for ammunition box sliding,based on a hydrostatic actuator,is proposed.The system configuration,operational modes,and working principles of the electro-hydraulic follow-up system for container sliding are described.A hydraulic circuit model of the system is established,and the influences of structural parameters such as system pipeline length,pipeline diameter,and orifice diameter on performance metrics(including follow-up time,reset time,and contact impact force)are investigated.The results indicate that the orifice diameter affects the contact force between the ammunition box and the baffle.As the size of the orifice diameter decreases,the contact force reduces correspondingly,while the follow-up time increases significantly.When the orifice diameter increases to 3.6 mm,the contact force exhibits approximately 20%oscillation,and the reset time of the ammunition box decreases.Therefore,within the structure of the follow-up container sliding system,the orifice diameter can be adjusted according to the requirements of rocket launch to achieve the tailored follow-up characteristics during the launcher's operation.
