The purpose of this paper is to clarify the mechanical strength of bolted joints from the both sides of experiment and theory when the joints are subjected to dynamic load. Therefore, the impact testing machine is produced experimentally. The analytical model is a bolted joints with filler plate which is fastened by a set of bolt and nut when joints are subjected to impact tensile load. In the theoretical analysis, the fluctuation in axial bolt force and stress distribution produced in the bolt are analyzed using the equation of motion including a damping ratio and other parameters. Corresponding to this theoretical analysis, experiments are performed in order to examine the strength properties of bolted joints subjected to tensile impact load. The analytical results are in a fairly good agreement with the experimental ones.
