| 摘 要： | 利用ANSYS软件研究了用于舰船基座抗冲击的计算方法，包括静g法、谱分析法（BV043／85规定谱、DDAM）和时间历程法。从改变系统固有频率出发，对单自由度系统和多自由度系统的位移响应和加速度响应结果进行了比较分析，对几种计算方法的优缺点进行了总结，并得出了相关结论。

| Abstract: | This paper studies the calculational methods of shock resistance of equipment foundations on ships with ANSYS software including static g method, spectrum analysis method (the prescribing spectrum in BV043/85, DDAM) and temporal signal method. Comparing the results of displacement response and acceleration response of the SDOF and MDOF at different natural frequencies, the advantages and the disadvantages of the three calculational methods are summarized and relative conclusions are drawn. |
