Abstract: To solve the problem of long erection time and high installed power of vehicle borne missile launcher, a quick erection scheme based on accumulator auxiliary power source was proposed. Firstly, a simulation model was established based on AMESim and Simulink software for the vertical system of multistage cylinder, and the energy distribution strategy and control switching strategy of the system were formulated. Then, the vertical speed and power characteristics of the system were simulated and studied, and the comparison of the system with the valve control system and the pump valve compound speed control system was carried out. The results show that the system can provide rapid and stable erection of the equipment, and can significantly reduce the system power, possessing reference significance for the upgrading of the erection equipment.
