摘要
首先利用ANSYS程序分析了潜艇内部弹、刚性连接平台在受到静载荷和谐响应激励作用下的响应,然后利用LS-DYNA对潜艇典型舱段在受到水下近场爆炸冲击作用时弹、刚性连接平台的响应进行了研究,并进行了弹、刚性连接平台的静动态响应对比分析。
The platform within submarine is the structure by which the equipments and foundations are to be supported and also the place for activities of crew. The weapon system and navigation-communication system installed are more sensitive to any shocks. The study of static and harmonic response of the inner platform for improving the survivability and combat capability of submarine is of significance. The responses excited by the static load and harmonic response of the inner platform with elastic and rigid supports via the finite element code ANSYS are analyzed. Then by using the nonlinear explicit dynamic element code LS-DYNA,the response of the elastic and rigid platforms of typical submarine compartment subjected to near-field underwater blast is investigated. The comparison results of the response between elastic and rigid platform tells the necessity of elastically supported platform in improving the survivability of submarine.
