To the widely used simple symmetric bevel gear differential, a fuzzy reliability-optimization mathematical model of a pair of bevel gear transmission is established, which used the bevel gear transmission as the research object, used the smallest volume of the gear transmission as the objective function, and used the end face module, the number of teeth and the coefficient of tooth face width as the design variables. Considering the randomness and fuzziness of the design parameters, an genetic algorithm control scheme was proposed for the optimal design, the numerical simulation results show that the volume of the gear transmission can be decreased by 3.36%, and the optimization design algorithm is more corresponded to engineering practice.

Bumper System

The bumper system always directly causes the injury of the pedestrian leg in the car–pedestrian accidents. Therefore, it is of practical significance to optimize the bumper structure to enhance the protective effect of the pedestrian leg. Based on the original bumper system, this work proposes a novel negative Poisson’s ratio energy-absorbing forepart with inner hexagonal cellular structure, which is designed at the lower leg impact zone between the bumper beam and the cover. The parametric model of the negative Poisson’s ratio forepart, the lower legform impactor model, and the car–pedestrian collision model are firstly established. Then, through integrating the response surface method, second-order reliability method, and archive-based micro genetic algorithm, a reliability optimization design is further conducted for the negative Poisson’s ratio forepart based on the deterministic optimization results. Simulation results show that the optimized negative Poisson’s ratio forepart not only can significantly enhance the reliability and robustness, but also improve the protective effect of the pedestrian leg.
