Simulation on Torpedo Water Cooling Support System with a Spring Piston Damper

为了降低鱼雷冷却水供应分系统压力脉动,防止振荡加剧,采用集中参数法建立了带弹簧活塞式缓冲器的鱼雷冷却水供应分系统的压力振荡模型,应用电液模拟方法得出了使用弹簧活塞式缓冲器后冷却水输送管路系统的频率,通过试验验证了弹簧活塞式缓冲器在鱼雷能供系统冷却水输送中的降幅变频特性,获得了很好的降幅效果,可为缓冲器在鱼雷海水供应中的设计、试验和使用提供参考。

To reduce the pressure oscillation of torpedo water cooling subsystem and avoid oscillation aggravation, a pressure oscillation model for torpedo water cooling support subsystem with a spring piston damper is established by using centralized parameter method. The frequency of the water cooling system with a spring piston damper is obtained by electro-hydraulic analogy. Experimental results verify that the spring piston damper can reduce pressure oscillation amiglitude and change frequency of the water cooling system.
