Abstract
The crashworthiness and energy absorption optimization of automobile structure is an important research content of the modern automobile industry. Facing the problem that traditional optimization methods are difficult to find the optimal solution for multi-objective parameters of vehicle structure crashworthiness problem, a multi-objective optimization method of vehicle crash safety based on improved particle swarm optimization is proposed. Through the collection and optimization of vehicle collision safety parameters, the vehicle structure performance is improved, and the vehicle regression model is constructed. Using this method, the front-end structure reinforcement of the vehicle is taken as the design variable. In order to realize the multi-objective optimization design method of vehicle collision safety, the multi-objective optimization parameters of vehicle frontal collision and offset collision are taken as the objective function. Finally, the simulation results show that the multi-objective optimization method based on an improved particle swarm optimization algorithm has an obvious effect on the optimization of vehicle structure crash safety.
