The invention discloses an unmanned aerial vehicle undercarriage buffer device which solves the problem of falling collision energy absorption in the landing process of an unmanned aerial vehicle in a manner of graded damage energy absorption deformation of a buffer. On the basis of the structural graded energy absorption damage concept design, the device is installed on an original unmanned aerial vehicle undercarriage, and the impact peak overload is effectively reduced and the impact kinetic energy transmitted to a fuselage is reduced in a graded damage energy absorption buffering mode during landing, so that the structural safety can be improved, and the crash survivability of the unmanned aerial vehicle is improved; meanwhile, the unmanned aerial vehicle undercarriage buffering device is simple in structure, low in cost and high in buffering energy absorption efficiency, can reduce the falling collision energy absorption requirement of the fuselage, and has positive significance in reducing the weight of the fuselage structure.
本发明公开了一种无人机起落架缓冲装置,以缓冲器分级破坏吸能变形的方式,解决无人机降落过程中的坠撞吸能问题。基于结构分级吸能破坏理念设计,通过安装在原有无人机起落架上,降落时以分级破坏吸能缓冲方式,将有效降低撞击峰值过载,减少冲击动能向机身传递,因而可增加结构安全性、提高无人机坠毁生存力;同时,该无人机起落架缓冲装置结构简单,成本低,缓冲吸能效率高,可降低机身坠撞吸能要求,对降低机身结构重量具有积极意义。
