柴油机是舰艇上的重要动力设备,其抗冲击能力对舰艇的航行能力和作战能力影响较大.通过建立的某型柴油机主要部件的有限元模型,计算了柴油机在动态运行时整机和各部件的响应,然后在柴油机动态运行状态下加载冲击载荷,得到了柴油机动态条件下的冲击响应,最后分析了动态运行条件对柴油机冲击安全性的影响.
The anti-shock capacity of marine diesel engine affects the shipping capacity and campaign capacity of navy ship, as the most important power equipment of navy ship. The finite element model of diesel engine is established, and the response of each diesel engine component is computed at the dynamic operation. Then, the shock load is taken to the model at the dynamic operation, and the shock response of diesel engine on dynamic operation is present. Finally, the influence of dynamic operation on shock security of diesel engine is analyzed.
