Aiming at the potential edge bearing problem of the helipad deck,as well as the contradiction between the deck weight and the bearing capacity,a multi-objective optimization design method is proposed in this paper.On the condition of avoiding the most dangerous taking off and landing situations,carrying out the layout of the plane size ranges and the static analysis of the current size by establishing plane coordinate system and deck size constraint inequality.The deck design variables are confirmed based on the deck weight,processing capacity and other constrains,so as to establish the quadratic polynomial response surface model(RSM)of the objective function,and experimental design sample points which uniformly distributed in the design space are obtained through Latin square hypercube sampling(LHS)method.The multi-objective optimization of the deck is performed using the Screening method to obtain the pareto feasible solutions and the response relationship between the design variables and the objective function,which provides the basis for the design of deck size and connector.
