The invention discloses a bionic clover negative Poisson's ratio car door anti-collision system and a layered optimization method thereof.The novel car door anti-collision system is designed by means of the advantages that a bionic clover negative Poisson's ratio structure is light in weight, high in energy absorption and easy to optimize, and the system comprises a car door anti-collision beam, a car door inner plate, a car door outer plate, a car door energy absorption block and a car door reinforcing plate; besides, the invention provides a hierarchical optimization method to perform optimization design on the novel vehicle door anti-collision system, and the hierarchical optimization method fuses a T-distribution-sparrow search algorithm T-SSA and a third-generation non-inferior sorting genetic algorithm ANSGA-III with a self-adaptive function, so that the comprehensive performance of the vehicle door anti-collision system is maximized, and the reliability of the vehicle door anti-collision system is improved. And the energy absorption and protection effects of the vehicle door anti-collision system are effectively improved.
