Abstract:
Water resistance is a major factor affect ing the law of motion of the automatic mechanisms in underwater firearms. The total kinet ic resistance of a moving part( a firearm bolt) was acquired by experiment because water resistance was difficult to be got accurately. The method is described as follows: the velocity of the moving part and the gas chamber pressure were measured with a dynamic test measurement system; a dynamic model was built on force analysis of the moving part; the total kinetic resistance replaced the horizontal frict ion and water resistance; then the resistance-velocity relation curves at moving stages were obtained; with the empirical formula of the gas chamber pressure and the resistance-velocity relat ion curves, the preliminary dynamic characteristics were analyzed and the structural form and key parameters of an underwater assault rifle were determined. The results show that the proposed method for dynamic analysis based on experiment is feasible.
