Abstract. Aiming at the actual demand of wide-frequency vibration isolation and low-frequency shock resistance of the vibration isolation system for complex external excitation of the aircraft turboprop engine. The dynamic performance of a certain type of turbo-propeller engine vibration isolation system at a 1.5–2000 Hz vibration frequency is investigated by combining simulations and experimental research. Firstly, an equivalent test device for the vibration isolation system of an aircraft turboprop engine is designed, and the reliability of the device structure is verified by finite-element analysis. Then, based on the trial model, sweep frequency vibration tests in three vibration directions are carried out, and the vibration isolation performance of the vibration isolation system under random excitation is analyzed. Finally, the transfer functions of the vibration isolation system in three vibration directions are calculated, and the vibration amplification of the vibration isolation system subjected to low-frequency resonance is analyzed. It provides a test basis and idea for the optimization design of the aero-engine vibration isolation system.
