TY - JOUR PY - 2021// TI - Topology optimization for crashworthiness and structural design of a battery electric vehicle JO - International journal of crashworthiness A1 - Zhang, Junyuan A1 - Ning, Linan A1 - Hao, Yumin A1 - Sang, Tao SP - 651 EP - 660 VL - 26 IS - 6 N2 - Electric vehicles have become the main trend of the future development of the automotive industry due to their advantages such as energy conservation and environmental protection, strong acceleration capability, and low noise. This paper uses a volume-produced fuel passenger vehicle P5 as a prototype. Based on the given driving mode and traction battery pack layout of a battery electric vehicle (BEV) EP5, considering the static stiffness and crashworthiness simultaneously, the equivalent static load (ESL) method is used to perform multi-load topology optimization on the body-in-white (BIW) of the BEV. Then the load paths of EP5 are proposed. The front-end structures of the vehicle body are redesigned by using topology optimization and size optimization, which improve crashworthiness and fully tap the lightweight potential of EP5.
