摘要: 针对火炮输药机构在小射角非满装药输药过程中到位一致性差的问题,提出基于稀疏混沌多项式展开的输药过程稳健优化设计方法。建立输药机构的动力学模型,并通过试验验证模型的正确性和有效性;基于稀疏混沌多项式展开求取不确定性输入参数对输药到位的代理模型;以模块药到位以及到位标准差最小为目标,建立输药过程的稳健优化设计模型,采用NSGA-Ⅱ优化算法对优化模型进行求解。计算结果表明:输药到位一致性得到了提高,且到位均方差较初始减小了26.74%,验证了该方法的有效性。

Abstract: For a propellant transport mechanism with small-angle propellant transport and non-full charge transport, a robust optimal design method for propellant transport mechanism based on polynomial sparse chaos expansion (SPCE) is proposed. A dynamic model of a propellant transport mechanism is established, and the correctness and validity of the model are verified through experiment. A surrogate model of uncertainty input parameters for position of propellant transport is obtained using SPCE. Finally, a robust optimal design model of a propellant transport process is constructed with the target of minimizing the in-place and standard deviations. The optimization model is calculated with NSGA-Ⅱ algorithm. The results show that the in-place consistency is improved after optimization, and the standard deviation is reduced by 26.74% relative to initial deviation, thus proving the effectiveness of the method.
