In order to study the work principle and separation features of an explosive separation device used in aerospace craft, this research establishes a three-dimensional finite element model based on ABAQUS software. Through simulation of separating process, the work principle is made clear, the separation time and maximum separation velocity are respectively 2.4 ms and 8.9 m/s. Meanwhile, a measurement system is designed for experiment and verifying the simulation results. The tested separation time and maximum separation velocity are respectively 2.8 ms and 7.5 m/s, which shows that the proposed finite element model and simulation can provide references for the research and development of explosive separation devices in aerospace crafts, as well, it is also an effective way to analyze and evaluate the feature of explosive separation device.
