“…The frequencies and damping ratios are provided by the time and frequency domain. 29 The wheel was fixed and tested on a test bench to verify whether the FEA results were in agreement with the experimental values. The wheel was fixed from the bolts to the bench, and accelerometers were fixed on the rim area of the wheel to perform measurements, as shown in Figure 5.…”

The weight and modal performance of the vehicle wheels are two essential factors that affect the driving comfort of a vehicle. The main objective of this study is to present an efficient approach to reduce the weight and enhance the modal performance of the wheel by reducing the design time and computational cost. The alloy wheel rim is often used for lightweight wheel design. In this study, an approach is presented for the lightweight design of alloy wheel rims. An intelligent approach based on neural networks (NNs) is introduced to predict the optimum design parameters of the wheel rim during the wheel design phase and to improve the wheel optimization process. The Latin hypercube and Hammersley designs of the experimental methods were used to obtain a training dataset with finite element analysis. The NN and multiple linear regression (MLR) models were trained to predict the weight, first-mode frequency, and displacement values. A multi-objective genetic algorithm was employed to optimize the design decisions based on the predicted values. It was used to compute the optimum results with both the NN and MLR models for a better prediction accuracy of the wheel rim design parameters. The proposed approach allows designers to optimize design decisions and evaluate design modifications during the early stages of the wheel development phase. The surrogate-based optimization method plays an important role in the wheel rim optimization process, particularly when the optimization model is established based on computationally expensive finite element simulations, testing, and prototypes. The results show the effectiveness of the NN-combined genetic optimization approach in predicting the responses and optimizing the design decisions for the alloy wheel rim design by reducing engineering time and computational cost.

“…However, pneumatic tires have several fatal drawbacks, such as catastrophic tire explosions, complex manufacturing processes, and the need to maintain internal inflation pressure [2]. In addition, pneumatic tires are often unable to withstand severe impacts and uneven road surfaces in harsh road conditions such as mines and military operations, thereby affecting the performance of vehicles [3][4][5][6]. In order to improve and overcome the shortcomings of traditional pneumatic tires, major tire companies and research institutes have increased their investment in research and development of safety tires.…”

The static and dynamic properties of the honeycomb non-pneumatic tires (NPTs) are strongly influenced by the spoke structure. Due to the complexity of the honeycomb structure, an in-depth understanding of the influences of the design parameters related to the honeycomb structure on its mechanical properties is essential, particularly for designing NPT of desired properties. Inspired by the concept of functionally graded structure, this paper aims to design a novel non-pneumatic tire with honeycomb-spoke graded thickness. Firstly, the in-plane mechanical characteristics of the thickness-graded honeycomb structures were investigated theoretically. On this basis, the finite element technique was developed for the NPTs using the corresponding thickness-graded honeycomb structures were established, and their static and dynamic mechanical properties were investigated using simulations and experimental tests. The results show that a reasonable thickness design can effectively enhance the load-bearing capacity of the NPT. The deformation features of the spoke were analyzed under the static state, and the contribution of different honeycomb structure edges deformation on the spokes is also discussed. The stress of the spoke and the tread under the static and dynamic loading conditions were studied, and comparison with the NPT-4 with a uniform thickness honeycomb structure, the results show that the thickness-graded honeycomb structure in NPT-3 significantly amplifies its load-bearing capability while also providing effective cushioning and shock absorption properties. This work would provide a basis for innovative design and performance optimization of NPTs.
