Parameter optimization of curing kinetics model of epoxy based on Ant-Lion Optimizer

摘要

For the sake of accurately obtain the reaction rate constant and reaction order in the curing kinetic model of epoxy resin, aiming at the problem that it is difficult to determine the parameters of the curing kinetic model of epoxy resin, the fitting problem is transformed into a multi-objective optimization problem, the coefficients to be solved are put into a vector into the fitness function, and the ant lion algorithm is used to iteratively optimize the optimal solution vector. Through coarse search and detailed search, the size of solution space is reduced, and the optimal roulette roulette strategy is added to prevent the algorithm from falling into the local optimal solution. Finally, Nash efficiency coefficient was used to test the fitting results. The test results show that the ant lion algorithm has high accuracy and application value in determining the parameters of epoxy resin curing kinetics model.
