Based on variable density topology optimization design theory, a numerical computation is carried out to optimize the chassis structure of new energy vehicles.
In the structure of new energy vehicles, the power battery pack structure is the most important power component, thus, it needs to be designed with a safer and more reasonable structure to meet the requirements of shock resistance and durability.
The optimized design of the chassis structure is to use advanced CAE technology to optimize the structure and size parameters of the parts, improve the utilization of materials, and remove unnecessary parts and components under the premise of ensuring or improving the performance of components and controlling the design cost.
According to the different function of the chassis structure spaces, the finite element model of chassis structure is divided into three parts: the front is the engine or motor mounting area; the middle is the battery system installation area, which also bears the mass of passengers; the rear is the trunk area.
After the optimization design of the battery box structure, the weight of the box is reduced by 0.62kg, and the maximum deformation of the whole vehicle in the collision is reduced from 239.1mm to 235.3mm, which means that structural design can realize the goal of weight reduction and safety improvement. 4. CONCLUSIONS
The design mass is fully loaded with 600 kg, and the mass is equally distributed in the middle of the chassis structure. So the chassis structure is a combined deformation of bending and torsion.
