Abstract: A new type of irregular lattice structure base floor was proposed, and its blast resistance was characterized and optimized. The parametric modeling program for the lattice structure base floor was developed, the blast responses of the base floor were analyzed based on the finite element method, the surrogate model between the lattice structure geometrical parameters and the blast resistance responses was established, and the rapid solution of the fitness function was realized. A multi-objective optimization design method for the blast responses of the lattice structure base floor was developed, and the lightweight design of the lattice structure was achieved The finite element analysis results show that, the optimized design of the lattice structure base floor achieves a 24.1% weight reduction and a 41.7% blast resistance improvement at the same time. This study provides methodological support and technical guidance for the design and application of irregular blast-resistance equipment such as armored vehicle base floors.
