Abstract:

Through researching the change of the target’s motion law under the influence of swaying, the mechanism of the effect of swaying on firing accuracy has been analyzed, and the increase of the target’s motion model error and deviation of advance point have been figured out to be the principal cause. The model for solving firing data based on iteration has been analyzed and built based on the research on model of projectile’s movement out of barrel. What’s more, the model for compensating swaying has been built, and the swaying motion of the ship and board has been effectively compensated. The simulation model and example have been designed to verify the effectiveness of the whole model, and the rationality of the analysis on the mechanism of influence on firing accuracy caused by swaying has been proved. The model and the conclusion can be used for improving the firing theory and firing technology.
