| 目的 研究软式飞艇着陆时，艇身弹性对起落装置的影响。方法 建立软式飞艇艇身和起落装置的等效模型，并在LMS仿真平台中建立虚拟样机，仿真出考虑艇身弹性时起落装置着陆的动态响应。结果 仿真结果显示出弹性艇身能够起到吸收和耗散能量的作用，减轻着陆时起落装置的过载和回弹次数。结论 艇身弹性可以降低起落装置载荷，延长起落装置寿命，增加飞艇的安全性。 |

| Objective To study influences of flexible fuselage on landing gear when a blimp airship lands. Methods An equivalent model of blimp airship with landing gear and flexible fuselage was established. An airship model with flexible fuselage using virtual prototype was applied in LMS simulation platform. Dynamic responses in landing of landing gear were simulated when the flexible fuselage was considered. Results Flexible fuselage was able to contribute to absorbing energy of shock absorber, alleviating overload and reducing rebound times during landing appropriately. Conclusion Flexible fuselage can decrease the burdens on landing gear, extend the life of landing gear, and improve the safety of the airship. |
