| 目的 研究拦阻和着舰过程中拦阻钩的动态响应，为拦阻钩的多冲动力学分析提供依据。方法 运用PAM-CRASH软件建立着舰拦阻冲击动力学的有限元模型，将整个过程分解为着舰和拦阻两个不同的阶段，考虑柔性体的建模方法。结果 通过仿真分析，得到拦阻着舰过程中响应最大的位置，得到绳索拦阻的最大载荷。结论 针对飞机拦阻钩结构动力学模型，就其啮合过程进行了动力学仿真，考虑飞机的航向及下沉速度综合作用下拦阻绳索的动态响应，探索了柔性拦阻绳索结构的动力学模拟方式。 |
| 英文摘要: |
| The work aims to study the dynamic response of the hook during arresting and landing, so as to provide the basis for the multi-impact dynamics analysis of hook. PAM-CRASH software was used to establish the finite element model of impact dynamics for landing arresting to divide the entire process of decomposition to two different stages, and the modeling method of flexible body was considered. Through simulation, the maximum response of the position in the process was obtained and the maximum load of rope was gotten. For the dynamics model of aircraft arresting hook, the dynamics simulation is carried out on the meshing process. Considering the dynamic response of arresting rope under the action of aircraft heading and sinking speed, the dynamic simulation method of flexible arresting rope structure is explored. |
