The invention provides an unmanned aerial vehicle vibration reduction undercarriage based on SMA, and relates to the technical field of vibration reduction. Each vibration reduction device comprises a first barrel, a vibration reduction rod, a first elastic assembly, a second elastic assembly and at least one SMA assembly, one end of each SMA assembly is connected with the stress end of the corresponding first elastic assembly, and the end, away from the corresponding first elastic assembly, of each SMA assembly is connected with the stress end of the corresponding second elastic assembly. According to the unmanned aerial vehicle vibration reduction undercarriage based on the SMA, the SMA assembly is matched with the first elastic assembly and the second elastic assembly to provide large elastic force and damping force, so that the energy dissipation capacity of the vibration reduction device is effectively improved, stable supporting of the unmanned aerial vehicle vibration reduction undercarriage is guaranteed, and the safe landing requirement of an unmanned aerial vehicle is met.
本公开提出一种基于SMA的无人机减振起落架,涉及减振技术领域,其中,无人机减振起落架包括:底座;多个减振装置,减振装置包括:第一筒体、减振杆、第一弹性组件、第二弹性组件和至少一个SMA组件,SMA组件的一端与第一弹性组件的受力端相连,且SMA组件远离第一弹性组件的一端与第二弹性组件的受力端相连。在本公开的一种基于SMA的无人机减振起落架中,SMA组件配合第一弹性组件和第二弹性组件能够提供较大的弹力和阻尼力,从而有效提升了减振装置的耗能能力,进而保证了无人机减振起落架的稳定支撑,满足了无人机的安全降落需求。
