基于熵权系数与TOPSIS法的航空发动机敏感性分析

Sensitivity Analysis of Aero-Engine Based on Entropy Weight Coefficient and TOPSIS Method

针对部分发动机试验中测量参数不足、无法满足建模过程中模型修正方程的问题,基于多目标决策问题的思想,提出了一种量化方式,将熵权法与TOPSIS法相结合,对发动机部件特性修正因子与试验测量参数的综合敏感性进行量化,并通过实例验证,证明该方法合理有效。

Aiming at the problem that the measurement parameters in some engine tests are insufficient and cannot meet the model correction equation in the modeling process,based on the idea of multi-objective decision-making,a quantitative method is proposed,which combines the entropy weight method and the TOPSIS method to evaluate the characteristics of engine components.The comprehensive sensitivity of the correction factor and the experimental measurement parameters are quantified,and the method is proved to be reasonable and effective by examples.
