The exposed platform is the main component of precision instruments such as pyrotechnic separation devices and load adapters, and its dynamic response characteristics are a key factor affecting the stability of aircraft. When the pyrotechnic separation device explodes, the exposed platform will be subjected to high-frequency, transient and high-order pyrotechnic impacts. High order pyrotechnic impacts can easily cause damage to sensitive components in onboard equipment, resulting in incalculable losses. Filling the honeycomb core cavity inside the exposed platform with a flexible boundary particle damper can effectively attenuate the pyrotechnic impact load after experiencing a large number of discontinuous structures. A numerical model of a flexible boundary particle damper and an exposed platform honeycomb panel was established through the coupling of discrete element and multi body dynamics. The effects of particle material, particle size, filling rate and flexible boundary film thickness on the impact reduction performance of the flexible boundary particle damper were analyzed, and the optimal characteristic parameters of the flexible boundary particle damper were obtained. The impact test was conducted on the honeycomb panel of the exposed platform using a light gas gun impact experiment, verifying the impact reduction effect of the flexible boundary particle damper and the accuracy of the numerical model. Finally, a pyrotechnic impact experiment was conducted on the exposed platform honeycomb panel with the optimal parameter flexible boundary particle damper. The experimental results showed that the impact reduction effect of the flexible boundary particle damper with this parameter reached 55.52%.
