| 摘 要： | 针对固体火箭发动机环境载荷的诸多不确定性,提出了环境载荷FHW量化评估算法.对比分析了火箭发动机的典型环境条件及其影响,采用熵值法确定了指标权重,基于FHW方法建立了火箭发动机的环境载荷评估模型,根据环境因素的分布特征给出评估指标的隶属函数,并获取其相应的灰色关联系数.算例验证了不同环境载荷因素对火箭发动机的影响程度,结果表明FHW评估策略和算法简单易行、精度高,在装备环境载荷量化评估中具有参考和应用价值.

Environmental Load Evaluation of Rocket Motor Based on FHW |
| |
| Abstract: | Considering that environmental load of solid rocket motor has lots of uncertainties,FHW evaluation algorithm for environmental load was proposed.The typical environmental condition and its influence on rocket motor were analyzed firstly.Then,index weight was determined with entropy method.The evaluation model of environmental load was established based on FHW method,the membership function of indexes was obtained according to the distribution feature,and corresponding relevance coefficient was acquired.Finally,the example verifies different influence degree of environmental loads,results shows that FHW evaluation strategy and algorithm are simple and precise,which will be referential and applicable in quantitative evaluation for environmental load. |
