The topological parametrization of load-bearing batteries and chassis structures is first introduced in Sect. 2, including the construction of the non-overlapping constraint with a minimum battery spacing control. Then, the concurrent TO model is constructed in Sect. 3.
control only changes the location of the batteries and the neighboring local topology of the chassis frames to satisfy the manufacturability for a specific connection technique, but has little impact on the overall load-bearing capacity due to the consistency of the entire structural weight and the material usage of each component.
On the basis of the mentioned approaches, Zhang et al. (2021) optimized the load-bearing battery layout and the structural topology simultaneously for a solar-powered drone, where each battery is regarded as an invariable dimension component and tightly installed on the wing structure.
The battery arrangement affects the load-deformation curves as the mechanical integrity in width and length direction is altered. Both Model W and Model L exhibit permanent plastic deformation at the end of impact events. Fig. 6.
Sensitivity of the mechanical behaviors and electrical failure to battery arrangement were discussed as well as the structure design on energy absorption capacity. These results hold significant potential for the safety and lightweight design of energy storage composite structures incorporating lithium-ion batteries. 1. Introduction
The load-bearing chassis structure can be designed throughout the whole design domain except for the wheels ( e = 0 , red solid line), the electric motors ( e = 0 , blue solid line) and the bumper beams ( = given region in the center of the EV chassis (dashed line). Three boundary conditions are taken into account with a same weight.
