喷雾干燥制备含能材料的神经网络模拟

摘要

含能材料降感一直是该研究领域的热点问题，其中喷雾干燥是一种有效的降感方

法。研究表明，喷雾干燥可以得到微米级的含能材料且能够实现连续化生产。但是由于

实验具有很大的危险性且实验过程较为复杂。而采用人工神经网络（ANN）对喷雾干燥

制备含能材料（CL-20、RDX 和 HMX）进行模拟，极大的降低了操作风险，对研究喷

雾干燥制备含能材料具有重要的意义。本文的主要研究内容如下：

（1）以气体流量、液体流量、入口温度、质量分数、相对分子质量和粘度为输入，

（3）对 GA 中的算子（选择算子、交叉算子和变异算子）进行优化，得到最佳参

数：选择算子为两两竞争法、交叉算子为均匀交叉和变异算子为均匀变异，其中交叉概

率为 0.8，变异概率为 0.1。并基于 Matlab GUI 建立平均粒径和粒径分布的预测界面。

（4）对比 GA-LR 和经验关联式的性能，考察了操作条件（气体流量、液体流量、

入口温度、质量分数和粘度）对平均粒径和粒径分布的影响规律，为定量计算提供理论

基础。

Artificial Neural Network Simulation of Energetic Materials

Abstract

The desensitization of energetic materials is a hot topic in this field, and spray drying is

(1) An artificial neural network model for energetic materials prepared by spray drying

was established with gas flow, liquid flow, inlet temperature, mass fraction, relative molecular

weight and viscosity as inputs and average particle size and particle size distribution as

outputs.

(2) Artificial neural networks were optimized by different types (Feed-forward back

propagation neural network (FFBPNN), Cascade-forward back propagation neural network

(CFBPNN), Elman-forward back propagation neural network (EFBPNN), Layers Recurrent

neural network (LR) and Nonlinear autoregressive neural network (NARX)), and different

algorithms (Levenberg-Marquardt algorithm (L-M), Momentum gradient descent and

adaptive learning rate algorithm (GDX), Genetic algorithm (GA) and Particle swarm

Based on the Matlab GUI, a prediction interface for the average particle size and particle size

distribution is established.

(4) By comparing the performance of GA-LR and empirical correlations, the effects of

operating conditions (gas flow, liquid flow, inlet temperature, mass fraction and viscosity) on

average particle size and particle size distribution were investigated, which would provide a

theoretical basis for quantitative calculations.
