Short summary
This study explores the actual demand of wide-frequency vibration isolation and low-frequency shock resistance of a vibration isolation system for complex external excitation of the aircraft turboprop engine. The performance of a type of turbo-propeller engine vibration isolation system at a 1.5–2000 Hz vibration frequency is investigated by combining simulation and experimental research.  It provides the test basis and idea for the optimization of the aero-engine vibration isolation system.
