The invention discloses a catapult-assisted take-off and arresting landing impact load simulation device and method. The catapult-assisted take-off and arresting landing impact load simulation devicecomprises a catapult-assisted arresting impact waveform control unit, a servo control unit, a sensing unit, an impact load loading device and a hydraulic power unit. In the catapult-assisted take-offand arresting landing impact load simulation method, through waveform preprocessing, the test loading feasibility of a reference waveform in a hydraulic servo driving mode is realized, and through a waveform correction control method, the control precision is improved. The method is based on a hydraulic driving mode, the loading and control problems of damping sine waves and time history waveformsspecified in an impact test program VIII of an eighteenth part which is an impact test in a GJB 150.18 A-2009 military equipment laboratory environment test method are solved, and the repeatability is good, and the test efficiency is high.
