Multi-objective optimization of airship structures based on genetic algorithm

WANG Yali;SAN Bingbing;ZHU Zhaoquan;College of Civil and Transportation Engineering,Hohai University;  
First,a multi-objective optimization model is proposed for airship structures. Three objectives and four variables are established according to the characteristics of airship structures. There are three objectives: minimum stress,minimum displacement and minimum weight. There are four variables: membrane thickness,membrane material elastic modulus,the internal pressure of airship and slenderness ratio. Secondly,weighting method is introduced to combine the three objectives into a single objective and a genetic algorithm is applied to solve this optimization problem. Finally,an example is provided to illustrate the proposed model and method. The study shows that the proposed multi-objective optimization model is feasible and efficient for airship structures; the desired optimal airship structures can be obtained by the weighting method and genetic algorithm. Reasonable suggestions are provided through the multi-objective optimization in the process of design.
