The invention provides a follow-up belt rotation device, a drop test bench and an undercarriage drop test method. The follow-up belt rotating device comprises a first machine frame, a lifting device ascending and descending in the first machine frame in the Z direction, a translation device transversely moving on the lifting device in the X direction and a driving mechanism arranged on the translation device and moving along with the translation device, and the driving mechanism outputs the rotation freedom degree. The power output end of the driving mechanism is provided with an electromagnet used for clamping the airplane wheel and enabling the airplane wheel to move along with the airplane wheel. The electromagnet is in contact with the radial side face of the airplane wheel, a stable and reliable connection mode is provided, the rotating speed of the airplane wheel can be accurately controlled, the airplane wheel is withdrawn in time before being in contact with the second platform, and a high-precision drop test is achieved.

    本发明提供一种随动带转装置、落震试验台及起落架落震试验方法。所述随动带转装置包括第一机架、沿Z方向升降于所述第一机架内的提升装置、沿X方向横移于所述提升装置上的平移装置、及设于所述平移装置上并与所述平移装置随动的驱动机构,所述驱动机构输出旋转自由度,且所述驱动机构的动力输出端上设置用于夹持机轮并使机轮随动的电磁铁。本发明利用电磁铁与机轮的径向侧面接触,提供一种稳定可靠的连接方式,并能够精准控制机轮的转速并在接触第二平台前及时撤出,实现高精度的落震试验中。
