Of An Automatic Mechanical System Dynamics Analysis

The firing technology of double cyclic systems and variable firing rate is an effective technical method to enhance the hit probability of rifles. In this paper, the overall design scheme of one assault rifle prototype with double cyclic systems and variable firing rate is illuminated in brief and the related analytical models of one DOF and two DOF by the basic theory of dynamics of multi-rigid-body system is established. The calculating analogue program in VB computer language for analyzing the movement regularities of floating body of the assault rifle prototype with some universal property and function of man-machine conversation is completed. The comparison between the calculating results and the experimental results is conducted also. Therefore the mathematical and physical models are verified. With the Pro/E software, three-dimensional models of the assault rifle prototype have been constructed and the whole assault rifle prototype has been assembled. With the ADAMS software, simulation of the assault rifle prototype has been .done. The primary factors influencing on the movement regularities of the floating body are obtained. The existing problems and the corresponding improvement opinions are pointed out. This paper provided a certain theoretical basis and method for the study of firing technology for rifles with variable-firing-rate and double cyclic systems and is of great value.
