چکیده
A hydraulic catapult system is proposed to simulate the movement of missile in launch tube, which mainly consists a high-speed cylinder, an accumulator group, main valve, servo valve and cable pulley mechanism. The key technical difficulties are that how improve response speed big flux increase limited stroke. An ingenious controlled designed mechanism applied lever. working principle design method discussed. Then mathematical model established, characteristics ejection process further investigated through numerical simulation. Theoretical results finally compared with experimental ones, it found they agreement. Finally, PID control system, show can accurately track velocity commands. This paper provides valuable reference for improving high performance aerospace field.
