“…The load path method based on * U index has an exceptional advantage for structural analysis (Pejhan et al, 2017;Takahashi et al, 2013) that can give a general awareness regarding the load-bearing performance. Therefore, the load-bearing performance of the structure can be determined by * U along the load path, and the design criteria is defined by authors (Wang et al 2021). The potential regions need to be optimized and the optimization suggestions can be identified by the criteria: when the * U along the main load path decreases too fast in some regions or when the load path in some regions has a larger curvature, the regions need to be optimized; while the regions with singular * U value, the materials need to be removed or the size needs to be decreased.…”

The existing bionic design methods are based on the similarity theory, but it is difficult to find a bionic prototype with high similarity for the control arm. In this paper, a design method combining load path analysis and biological characteristics is proposed to realize the lightweight of control arm. The load path is used to visualize the load-transferred law in structure and identify the load-bearing performance. Then, the structural improvement suggestions are given and a new control arm with the coupling load of bending moment and pressure is established. Then, the cross-section of wheat-stalk is selected as the cross-section of control arm from four kinds of plants including Bamboo, Wheat-stalk, Juncus, Brazilian Horsetail because of its good bending-resistance and torsion-resistance. The bionic model is designed and the mechanical performance is analyzed and verified by Finite Element Analysis. The results show that the stiffness and strength of the control arm are improved by 65.6% and 22.5% respectively, and its weight is reduced by 32.7%, which show the feasibility and efficiency of the proposed method.

“…However, the method is mainly applied to evaluate and improve the loadbearing performance of a given structure, and still lacks a detailed optimization method for structural design. 20 In this paper, a shape optimization method for wheel rims is proposed. The outstanding contributions include: (1) The load-transfer law in the wheel rim section is revealed to guide the structural design for the first time; (2) A detailed optimization strategy based on load path analysis is established, which points out the design and optimization direction for a given structure.…”

The wheel rim is an annular and thin-walled structure with complex structural features and working conditions. Guaranteeing its safety and lightweight are two major concerns in wheel rim design. In this study, a shape optimization method based on load path analysis is proposed to evaluate and optimize the structure of the wheel rim. The load-transfer law of the wheel rim is identified based on the load path visualization. Two design criteria are put forward to evaluate the load-bearing performance and give the improvement suggestions. Then, the shape optimization problem is simplified to a parameter optimization problem, and the optimal size combination performance-oriented is obtained using the non-dominated sorting genetic algorithm II (NSGA-II). As a case study, a wheel rim is redesigned and the optimization result shows that the stiffness and strength are improved under bending and radial fatigue simulation, while the weight is reduced by 3.78%. Two stages of experimental studies are carried out to verify the optimization method. The static pressure test shows that the bending resistance performance of the wheel rim is improved by 4.57%, and the load transfer is more uniform. The radial impact test shows that the impact deformation at a high energy level is reduced by 13.77%, indicating that the impact resistance performance is significantly improved.
