【 摘 要 】

Aiming at the problems of slow opening speed and high power of hydraulic system for traditional special opening and closing mechanism, a gas-driven opening scheme is proposed. Combined with the working environment of the special opening and closing mechanism, the opening mode and principle of the opening and closing mechanism were analyzed. The gas ejection system was designed, and the dynamic model of the opening and closing mechanism was established according to the actual mechanical structure. The focus is on the design of the internal ballistics of the system, and the relevant parameters of the gas ejection system are finally determined based on the simulation results. The numerical test results show that the method can be opened within the specified requirements of the opening and closing mechanism. Compared with the traditional method, the opening time is greatly shortened, which has theoretical feasibility and can provide reference for the opening of the special opening and closing mechanism.
