摘要/Abstract

摘要： 针对某自动装填系统弹丸提升装置在使用过程中出现的性能下降问题，提出一种考虑区间不确定性的提升装置参数优化方法。基于动力学分析软件ADAMS建立提升装置的机电液耦合模型，将液压系统参数和摩擦系数作为区间不确定量，利用区间数序关系将构件载荷及其波动区间最小转化为确定性优化目标。采用拉丁超立方抽样(LHS)技术进行抽样仿真，基于径向基函数(RBF)神经网络方法构建了提升装置的近似模型，大大提高了优化求解效率。基于多岛遗传算法和序列二次规划法的双层嵌套优化方法求得系统的鲁棒解，仿真结果与试验结果均验证了该方法在解决自动装填系统等复杂问题中的有效性和适用性。

Abstract: An optimization method for shell elevating device with interval uncertainties is proposed to solve the problem of performance degradation during operating. A multidisciplinary model based on ADAMS is established. The parameters of hydraulic system and the friction coefficient are regarded as the interval uncertainties, and the minimal loading and fluctuation on the mechanism are set as the objectives by using the interval theory. Simulations are carried out on Latin hypercube sampling (LHS) points. An approximate model of shell elevating device is constructed based on radial basis function (RBF) neural networks to improve the efficiency. The nested optimization method based on multi-island GA and NLPQL is used to obtain the robust solutions. The simulation and experimental results demonstrate the efficiency and adaptability of the proposed method for solving the complex problems in automatic loading system.

Key words: ordnance science and technology, automatic loading system, elevating device, parameter optimization, interval uncertainty, radial basis function neural network
