Abstract

Abstract:

In order to improve the inadequate firing accuracy of the existing prototype of a 30-mm caliper gun overhead weapon station, a triple-index constrained optimization model with damper is developed with the consideration of a real-world operating environment. Furthermore, a method of deriving the characteristic parameters of the damper is proposed based on the triple indices, and the optimal damping parameters are obtained. Simulation results show that the dynamic characteristics of the automatic-firing muzzle of the overhead weapon station with the proposed damper have been significantly improved, where the dispersion variances of horizontal and pitching are decreased by more than 30%, indicating that the firing accuracy is considerably enhanced. The result can be applied for the development of overhead weapon stations in the future.

Key words: the overhead weapons station, optimization of dynamic characteristics of muzzle, the damping buffer device, triple-index constraints
