摘要/Abstract

摘要： 为了提高弹丸卡膛一致性，以减小弹丸卡膛起始点运动参数波动即提高输弹一致性，根据输弹机工作原理和输弹实验，归纳了输弹系统中的随机参数。基于ADAMS软件建立了考虑参数随机性的某输弹机输弹过程动力学模型。以弹丸卡膛起始点运动参数标准差最小为目标，以卡膛速度下界达到3 m/s为约束，建立了面向输弹一致性的输弹机稳健优化模型。采用全局和梯度组合优化算法以及描述抽样，提高了优化计算效率。数值算例结果表明，优化后输弹机卡膛速度满足要求，输弹机的输弹一致性得到提高，验证了所提方法的有效性。

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.
