The invention relates to the technical field of unmanned helicopters, and provides an unmanned helicopter gravity center adjustment and energy absorption damping device which comprises a vibration absorber structure, a translation structure, a guide part and a driving mechanism. The vibration absorber structure comprises a vibration absorption connecting structure, airborne equipment and a plurality of elastic connecting pieces, the airborne equipment is installed on the vibration absorption connecting structure, the vibration absorption connecting structure is connected to the translation structure through the elastic connecting pieces, and the driving mechanism is used for driving the translation structure to move along the guide piece. A dynamic gravity center deploying system and a vibration absorption system are integrated into one system, the connecting rigidity of the system is adjusted to be matched with frequency doubling of a main rotor of the unmanned helicopter, and airborne large-mass equipment (an airborne storage battery) is used for constructing a local single resonance system for dynamic energy absorption and vibration reduction and the dynamic gravity center deploying system. Therefore, introduction of extra counterweight mass is avoided, the damping effect is achieved, the effective load weight and space of the helicopter are not occupied, and the range of the gravity center can be dynamically adjusted.

    本发明涉及无人直升机技术领域,本发明提供了一种无人直升机重心调整及吸能减振装置,包括:吸振器结构、平移结构、导向件、驱动机构;吸振器结构包括:吸振连接结构、机载设备和若干弹性连接件,机载设备安装于吸振连接结构上,吸振连接结构通过若干弹性连接件连接在平移结构上,驱动机构用于驱动平移结构沿着导向件移动。本发明将动态重心调配系统与吸振系统整合与一个系统当中,将本发明连接刚度调整到与无人直升机主旋翼倍频相匹配,利用机载自有的大质量设备(机载蓄电池)构造局部单一共振系统进行动力吸能减振与动态重心调配系统,从而避免额外配重质量的引入达到减振效果,不占用直升机的有效载荷重量与空间,可动态调整重心的范围。
