Design of hydraulic power subsystem in shock simulation system for shipborne weapons

The category of shipborne weapons as well as the importance and effect of naval gun mounting servo system are described. The status and difficulty in type approval test of naval gun mounting servo system are introduced. A shock simulation testing system for shipborne weapons based on electrohydraulic servomotor is put forward, which can simulate all levels of ocean wave shocks, inertia moment and shooting shocks. Performance of hydraulic power is analyzed according to power requirement of simulation system, mechanical structure of subsystem is confirmed, and diameter calculation for hydraulic oil supply pipe as well as type selection for power accumulator are accomplished. Experiment result shows that this simulation system meets with the technical design requirements.
