摘要
姿态控制系统减压阀采用收缩喷嘴节流结构进行减压过程中,产生压力脉动,可能诱发调节系统低频或高频振动。调节系统的低频或高频振动进一步可能产生共振,引起减压阀失效。分析认为采用控制激振因素、控制系统固有频率、消减压力脉动和消耗振动能量的方法可以控制大幅度的振动。
The regulator of the attitude control system is designed to decrease vessel pressure through the convergent nozzle. The regulating system has found low or high frequent vibration due to the pressure oscillation, and the sympathetic vibration can occur and induce regulator invalidation. The vibration can be reduced by controlling the triggering factors and intrinsic frequency, restraining pressure or draining kinetic energy.
