摘要
参照德国军标BV043/85[1]及文献[2]的设备冲击谱公式,研究了舰船基座在水下非接触爆炸条件下的冲击载荷,并对某柴油机基座进行了抗冲击计算。文章分别计算了基座在静载荷和冲击载荷作用下的应力及变形,其中冲击计算采用了静G法和时间历程法两种方法。计算结果表明,水下非接触爆炸造成的冲击载荷对舰船基座应力、变形产生重大影响,在基座设计中不容忽视。
The shock load of equipment pedestal in the naval ship is researched when explosive occurs under water. To the detail, the shock resistance ability of one diesel engine pedestal is calculated referring to the shock spectrum formulations from German military specification BV043/85 and literature[ 2 ], The stress and deformation of the searing are separately calculated when the pedestal endures static loadings and shock loadings. There are two ways to calculate the results of shock loadings: static G method and temporal signal method. The results shows the indirect under water explosive make sever influence to the pedestal it can never be neglected during the process of design,
