拖曳式声纳收放架抗冲击能力时域分析
Time-domain Analysis of Shock Resistance Ability of Retractable Equipment of Towed Sonars
摘要
Abstract
The retractable equipment used for winding and towing sonars is an important equipment to guarantee the normal working condition of the sonar and the other important equipment. In this paper, the shock resistance ability of the retractable equipment was simulated in time-domain under different working conditions. The results show that the retractable frame can meet the anti-shock requirement under different working condition, but in the sonar recovery process, the peak value of the stress near the located hole on the base is close to the allowable stress, thus, the hole needs to be reinforced. Then, the acceleration responses of the propulsion system and the headstock system were studied. The results show that the suspended equipment can yield a secondary oscillation phenomenon, which can cause the peak response acceleration to exceed that during the shock.关键词
