The invention belongs to a test device in the field of rotating machinery, and discloses a dynamic characteristic test device for a high-speed flexible rotor system of a GTF engine, which comprises a driving system, a low-pressure shaft, a low-pressure compressor, a low-pressure turbine, a simulation transmission device and the like, the relative positions of a sleeve and a ball bearing of an equivalent rotor system are adjustable, and a squirrel-cage elastic support is replaceable. The disc shaft connecting shaft neck can be replaced; the gyro load of the wheel disc can be changed; the membrane disc shaft can be replaced; the interactive excitation effect of the flexible rotor and a transmission device can be changed; the contact type vibration exciter can apply complex excitation possibly possessed by a real gearbox to a transmission device supporting structure, the device is compact in structure and easy to disassemble, and the dynamic characteristics of a high-speed flexible rotor system of a GTF engine c
