Design of shock simulation system for shipborne weapons based on electrohydraulic servomotor

The variety of shipborne weapons as well as the importance and affect of naval gun mounting servo system are narrated. The existing conditions and problems of naval gun mounting servo system in type approval test are introduced. A new kind of shipborne weapons shock simulation testing system based on electrohydraulic servomotor is given, which could simulate all levels of ocean wave strokes, weapon system inertial moment and shooting strokes. The nominal pressure and flow of both high-power low-frequency hydraulic motor and miniwatt high-frequency hydraulic motor are confirmed by analytical calculation. The experiment demonstrates that the performance of this simulation system meet with the designed technical requirements.
