摘要
针对中间轴承抗冲击性能，建立某型舰用中间轴承抗冲击数值仿真模型，基于现代冲击基础理论，采用频域法对其进行抗冲击性能仿真，计算得到不同冲击载荷作用下中间轴承各部件的应力分布，为其抗冲击设计与评估提供参考依据。研究结果表明，该型舰用中间轴承符合GJBl060．1—199l抗冲击要求。
According to requirements of GJB1060.1--1991, a numerical anti-shock model of a kind of intermediate bearing was established. Based on modem impact theory, the anti-shock performance of the intermediate bearing was simulated in fre- quency domain. The stress was obtained, which could be used for anti-shock design and evaluation. The results indicated thai the design of intermediate bearing met the anti-shock requirements of GJB1060.1--1991.
