“…According to SAE J175, 22 the commonly used mechanical performance tests for automobile wheels include the bending fatigue test, 4 radial fatigue test, 23,24 13°side impact test, 25,26 and radial impact test. [27][28][29] The local regions of the wheel hub bear different loading modes under different tests, including the surface loads caused by tire pressure, the bending moment caused by tire installation load and axle, as well as the axial and radial impact loads caused by 13°side impact and radial impact tests.…”

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.

Composite materials are widely used in automobiles because of their small proportion, large modulus and high strength. In this paper, carbon fiber-epoxy (T300/5222) composite material is used to design the composite automobile wheel hub according to the general principle of laminated plate design. And the hub layer is finished with hypermesh 14.0. The stress and strain of the hub can be analyzed by Hyperworks14.0 according to the three kinds of conditions. Then the maximum stress layer is found out and the strength is checked. The composite wheel hub is compared with the same aluminum alloy hub. The results showed that composite materials of hub can be achieved in hub strength requirements. Because its ultimate stress is bigger than Aluminum Alloy of hub, obviously the strength of composite hub is higher than the Aluminum Alloy of hub. Because of the smaller strain, the impact of performance is better. The composite wheel hub reduces the weight of 11.3%.

“…In the literature, a certain number of papers dealing with the numerical simulation of such tests can be found. A large variety of numerical models of the 13 • side impact test have been proposed in the literature [14,15,16,17,18,19]. In all those references, finiteelement based models have been employed for the numerical simulations.…”

“…An accurate modelling of the tyre requires a deep knowledge of the actual structure and of the rubber materials that compose the tyre carcass [14]. To overcome this difficulty, some attempts have been made to develop a simplified approach for the numerical modelling of the 13 • side impact test [17,20]. In [17], the simplification consists in removing the tyre from the model and in reducing the kinetic energy of the striker by 20% to compensate the tyre absence.…”
