摘要

摘 要: 介绍了舰船设备抗冲击计算的动态设计计算法(DDAM)和时域模拟法,根据舰船动力机组各组成设备的结构特点,分别采用DDAM方法和时域加载法在频域和时域上对其进行抗冲击计算分析。计算分析结果表明,不同设备对冲击载荷的响应与设备本身的结构特点有关,且与冲击加载方向有很大关系。对于主汽轮机组和主减速齿轮装置,由于各个构件之间存在连接关系,螺栓、销钉及其连接结构的动态响应更为敏感。所得分析结论可以对开展舰船设备抗冲击计算分析以及新型舰船设备的抗冲击设计提供一定的参考。

Abstract

Abstract: The dynamic design calculation method DDAM and time domain simulating method are introduced in this paper. Basic on the structure characteristic of the ship power package parts, the DDAM method and time domain load method are introduced respectively in frequency-domain and time –domain to analyze the shock resistance. The result indicates that the responses of different devices are relationship with the structure characteristic and the shock load direction. To the main turboset and the main reducing gear device, because of the connecting relationship between the parts, the dynamic response of the bolt, dowel and the connecting structure of them is more sensitively. The results can give certain reference to the analysis and calculation of the ship device shock resistance and the shock resistance design of the new ship device.
