Abstract:

Through the classical lamination theory and coordinate transformation, the material model is simplified, and the modeling of complex laminated composite is avoided. A multi-objective improved immune clonal cuckoo algorithm (MOIICCA) is proposed for the multi-objective optimization of fiber winding constrained structure of electromagnetic gun. The accuracy of MOIICCA algorithm is verified by 100 simulation calculations of ZDT1-ZDT3 test function, and the performance of MOIICCA algorithm is measured by inverted generational distance (IGD) evaluation index. By introducing the learning method of deep neural network and taking 646 groups of electromagnetic gun finite element calculation results as the training set, the deep neural network agent model which meets the engineering application requirements is trained to replace the finite element simulation, thus improving the computational efficiency of multi-objective optimization. Finally, MOIICCA algorithm is used to optimize the constrained structure of electromagnetic gun fiber winding, and the Pareto solution set is obtained. IGD results show that MOIICCA algorithm has higher computational accuracy and efficiency than the multiple objective particle swarm optimization algorithm and the non-dominated sorting genetic algorithm II, and has more advantages in solving the high-dimensional problems, and t. The test results also show that MOIICCA algorithm can get better Pareto set in a shorter time. The results of the first 10 sets of Pareto solutions show that the fiber layer 1 of the winding structure mainly improves the circumferential strength, and the fiber layer 2 mainly balances the circumferential strength and axial stiffness.
