摘要
针对液体火箭箭体结构的安全性问题,提出一种利用置信规则库(belief rule base, BRB)和鲸鱼算法(whale optimization algorithm, WOA)模型来进行安全状态评估的方法。该模型基于BRB方法对液体火箭结构安全进行安全状态评估,最后基于WOA优化算法对构建的BRB模型的参数进行优化。由实验可知,所提出的模型能够有效解决液体火箭箭体结构安全性评估的问题,同时能够充分进行半定量分析,并保持较高的实验精度。
Aiming at the safety problem of liquid rocket body structure,this paper presents a method to evaluate the safety state by using belief rule base(BRB)and whale optimization algorithm(WOA)model.The model evaluates the structural safety of liquid rocket based on BRB method,and finally optimizes the parameters of BRB model based on WOA optimization algorithm.It can be seen from the experiments that the proposed model can effectively solve the problem of structural safety evaluation of liquid rocket,and can fully carry out semi-quantitative analysis and maintain high experimental accuracy.
