Abstract: The bolted/riveted joints are widely used in spacecraft structures, and their impact resistance is vital for the safety of the whole structure. This paper builds a theoretical model of the electromagnetic force driving based on the RLC circuit, and a system for testing the impact property of bolted/riveted joints. Two loading methods are proposed, namely, the direct loading and the impact loading. The former is suitable for medium strain rate impact test with high impact energy absorption and a strain rate of less than 150 s^-1 under the impact loading, while the latter is suitable for medium strain rate impact tests with a low impact energy absorption and a strain rate of less than 500 s^-1 under the impact loading. The device and the method are tested and verified. It is shown that the device and the method can be used to test the impact mechanical properties of joints under medium- and-low strain rate loading with the advantages of small volume and low cost. The result of the study can be applied to the assessment and the optimization of the impact properties of spacecraft joining structures.
