Abstract
A 3-D elastic-plastic dynamic finite element model for the generation of incident pulse in the rotating disk indirect bar-bar tensile impact apparatus is established in the present paper. The numerical simulation is solved by ANSYS/LSDYNA. The numerical result thus obtained is in good agreement with that from the experiment, which confirms that the model and the method are effective. Based on the numerical results of different working cases of the indirect connection system and the result comparison between the indirect and direct connection systems, the process and the mechanism of the generation of smooth and stable incident pulses in the apparatus are discussed. The mechanical filter function of elastic-plastic deformation till fracture of the prefixed short metal bar is also discovered. Furthermore, the effect of geometry of the short metal bar and impact velocity on the rising time, amplitude and duration of the incident pulse is demonstrated. The matching condition of producing a long-duration incident pulse is proposed.
