摘　　要：法兰式液压联轴器作为船舶动力传递的关键部件,在造船工业中得到了越来越广泛的应用,但目前对其抗冲击特性研究较少。本文基于非线性接触理论,建立某法兰式液压联轴器接触模型,获得最大负载工况下联轴器各部件的应力分布。在此基础上,基于现代冲击理论,分别采用频域法和时域法进行抗冲击特性分析。计算得到液压联轴器在冲击载荷作用下的应力分布,为舰载设备抗冲击性能评估和设计提供依据。研究结果表明,该型液压联轴器符合抗冲击性能要求。Flanged hydraulic couplingis an important junction and is being widely used in modem naval shaftingsystem. However, few researches have been studied on its anti-shock performance. Based on nonlinear contact theory, a finite element model of a flanged hydraulic coupling was built in this paper. The distribution of the contact stress was obtained in the working condition of maximum load. Furthermore, based on modern impact theory, its anti-shock performance was studied in both frequency and time domain withthe consideration of the contact stress. The stress was obtained from the anti-shock simulation which could be useful for anti-shock design and evaluation. The results indicated that the design of flanged hydraulic coupling met the requirement of anti-shock.
