Dynamic Modelling of a Novel Design of 120mm APFSDS Training Round.

摘要

A novel design for a low cost, high volume production, APFSDS training round has been proposed for use in 120 mm tank gun systems. The design of this round is unusual because of the method of support between the penetrator and the sabot, and also in the way in which the forces are transmitted to the penetrator in order to accelerate it up the bore. This has meant that the standard gun dynamics model has required modifying in order to produce meaningful simulations. This paper describes the design concept and the way in which an existing gun dynamics simulation package has been used to model the round in order to optimise its design parameters. The results from these simulations have been successfully used to assist the design iterations during development, and achieve the project requirements.
