| 摘 要： | 考虑到设备冲击极限载荷作为舰艇抗水下爆炸冲击设计与评估的重要基础,为了获取舰用设备冲击极限载荷特性,建立了某舰用齿轮箱的有限元模型,采用容许应力法分析了该设备的冲击极限载荷特性.结果表明,容许应力法是一种直接、有效获取舰用设备冲击极限载荷的计算方法,舰用齿轮箱的冲击极限载荷与输入载荷的加速度峰值和脉宽相关.

| Abstract: | Considering the shock-resistance threshold of equipment on board as the important base for ship shock-resistance design and assessment, a finite element model of marine gearbox was established to get the characteristic of shock-resistance threshold. The shock-resistance threshold was analyzed using endurable stress method. Results indicate that endurable stress method is a direct and effective computational method for getting shock-resistance threshold of marine equipment. The shock-resistance threshold of marine gearbox is related to the peak value of acceleration and pulse width of input load. |
