摘要
本文通过实艇的强度、稳定性分析,论述了丧失舱段总稳定性是潜艇耐压壳体在深潜时的主要破坏模式,振动固有频率是表征其稳定性储备的特征量。模拟实际潜艇结构、装载、安装的设备、制造公差及腐蚀等进行了一系列的计算和实验验证。所有结果证明通过振动固有频率进行稳定性监测的可行性,据此提出了监测装置的组成。
By analyzing the strength and stability of a real submarine, it is concluded that instability is the main case of submarine damage. With Finite Element Method, a series of stability analysis for a cylindrical shell, which is similar to the real construction of a submarine hull is carried out. The monitoring of its natural frequencies is proved to be an effective way to safety monitoring. The stability monitoring system is proposed and discussed.
