Abstract

Abstract: The fluctuation of projectile motion parameters before bayonet-chamber is reduced, i.e., improving the consistency of ammunition ramming, to improve the consistency of bayonet-chamber. The random parameters in the ramming system are summarized according to the operating principle of ramming mechanism and the experimental results. Based on MSC.ADAMS, a dynamic model for ramming process of a ramming mechanism, in which the parameter randomness are taken into account, is constructed. A robust optimal design model of ramming mechanism for consistency of ammunition ramming under the constraint of minimum 3 m/s bayonet-chamber velocity is established for minimizing the standard deviation of the motion parameters before bayonet-chamber. The optimization calculation efficiency is improved by using the global and local combinatorial optimization algorithms, and the descriptive sampling. Numerical examples show that the bayonet-chamber velocity meets the requirements, and the consistency of ammunition ramming is improved after optimization, which verifies the effectiveness of the method.
