- Abstract:
- Since there are as many as nine vehicle collision conditions and the collision forces of different conditions vary greatly, the final overall topology configuration will be more inclined to the conditions with large collision forces when performing multi-condition parallel topology optimization on the car body, and the front, Due to the different collision forces in the passenger area and the rear of the vehicle, the optimal optimal mass ratio is also different, so the multi-condition crashworthiness topology optimization of the entire body cannot be carried out at the same time. In order to obtain a vehicle configuration with a reasonable and effective material distribution, the same The model conducts a comparative analysis of the overall topology optimization and sub-area topology optimization, and proposes a topology optimization of the seating area first, and then optimizes the topology of the front and rear of the vehicle when the structure of the seating area is known, and finally assembles the topology of the entire vehicle. Topology optimization design method for crashworthiness of body-in-white based on optimization model.
