“…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 maximum stress and displacement values of the wheel hub in equation ( 6) can be calculated by Finite Element Analysis (FEA), which has been studied by numerous scholars. 4,23,24 The maximum stress value and displacement value of the initial wheel hub are first calculated here. For the bending fatigue test, the load axle length of the wheel hub is 760 mm, and the remote force is 4539.47 N. The FEM of the load facing the valve hole is established in Figure 20.…”

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.

“…Due to road safety, the wheels are subjected to endurance tests [38]. The scope of the tests includes the measurements of stresses during the simultaneous action of bending and torsional moments as well as fatigue tests [39][40][41]. The next laboratory tests that the wheels are subjected to are impact tests.…”

The article presents the results of simulations using the finite element method (FEM) aimed at examining the extent of damage to the wheel rim as a result of hitting an obstacle. The obtained results can be used as comparative data during the performance of expert opinions to give an answer as to how the damage occurred. The data obtained from the FEM simulation can also be used in the process of geometric optimization of the rim, which aims to obtain a rim resistant to this type of damage.

“…The bending moment is applied through a rotating mass acting on a central shaft fastened at the wheel hub. In the biaxial fatigue test [7,8,9], the wheel and tyre assembly is left to rotate on a rolling drum; different combinations of vertical and lateral forces are applied according to well defined load sequences [10].…”
