Static and Modal Models of Automotive Wheel Hubs Based on Lightweight Design and Cost-Effectiveness
Round 1
Reviewer 1 Report
The article is devoted to the static and modal analysis of automobile wheel hubs based on lightweight design and economic efficiency. The results of the modal analysis of the oscillation frequency of the optimized wheel hub are presented. The article carried out a further analysis of the effect of lightening the wheel hub and proposed a scheme for replacing the lightweight material. However, there are some remarks about the work:
1. In the title of the article, analysis should be replaced with models.
2. The structure of the article is not presented in the introduction, and the purpose of the study is not distinguished by scientific novelty.
3. Figure 7 is hard to read, it needs to be made clearer, the inscriptions are not visible.
4. On Figures 8,9, 11, 12 the inscriptions are not readable, it is necessary to correct the drawings.
5. There is no Discussion section, which allows characterizing the obtained models and obtained scientific results.
6. The article provides simulation modeling in the ANSYS ICEM environment, there are no experimental studies, as well as comparisons with other information sources, confirming the effectiveness of the presented model and solutions.
7. It is necessary to bring a mathematical model of the behavior of the disk and hub for static and dynamic loads.
8. Conclusions should be structured, highlighting the main scientific and practical results obtained, supporting them with quantitative information.

Reviewer 2 Report
In this paper, the authors perform basic static and modal deformation analysis of rims.
To demonstrate a scientific approach to rim design, consider the following
- author should use at least low-cycle, if not high-cycle, deformation stress response of the material
- consider the influence of the tires in the modal analysis
- perform a dynamic analysis of the rim during normal operation
- perform a safety analysis against the occurrence of permanent deformations or cracks
- only on this basis can the geometric optimization of the rims be carried out

Reviewer 3 Report
This study aims to optimize automotive wheel hub designs by considering lightweight and cost-effective factors. Static and modal analyses were conducted using finite element analysis to understand the wheel hub's response to loads. Optimization techniques were employed to improve its strength and stiffness while reducing its mass. The optimized wheel hub's deformation, stress distributions, and vibration frequencies were analyzed and met design requirements. The study also explored lightweight materials and validated the optimized wheel hub's performance through comprehensive static and modal analyses. The following comments and recommendations may be helpful to improve the paper:
Q-1: In the introduction, the optimization of automotive wheel hub structures is a critical aspect of enhancing vehicle performance, efficiency, and overall design. In recent years, there are different solutions to be proposed to enhance the efficiency of wheel hub mainly from two perspectives, one focus has shifted towards lightweight and cost-effective solutions that maintain or improve structural integrity; the other angle is that the efficiency of the wheel hub has been improved through the application of optimization control algorithms, which needs to be discussed briefly in this part to strengthen your motivation: hierarchical energy efficiency optimization control strategy for distributed drive electric vehicles; comprehensive chassis control strategy of FWIC‐EV based on sliding mode control.
Q-2: In column 76, wheel hubs are complicated, so their performance is influenced by multiple factors. So, more review should be conducted to make the paper more comprehensive, and to provide strong evidence, such as the factor errors in the mechanical structure when utilizing the different motors, for example: research on synchronous control strategy of steer-by-wire system with dual steering actuator motors.
Q-3: Most figures, like Figure 1,2 ,7, are not clear, it is better to be improved by providing the results with high quality, which make the paper more readable.
Q-4: It is better to summarize your conclusion into four bullet points from the different perspectives according to your simulation and validation results, for instance, the first point is Static analysis of the wheel hub, second one is modal analysis of the wheel hub, the third one is optimization design of the wheel hub, and the last one is lightweight analysis of the wheel hub.

1. No optimization method was used, only carried out the static and modal analysis for two specific hub design;
2.The hub geometry parameters should be pointed out and their effect on the stress and deformation should be investigated.
3. The quality of figures should be improved, the numbers on the figure are not clear.
Generally, the quality of english is acceptable.

Round 2
Reviewer 1 Report
In general, the authors have finalized the article.
But I would like the answer to my 6th remark to be given in the text of the article.
Also strengthen the discussion section a little more, according to the fifth remark.

Reviewer 2 Report
For a scientific article, it is necessary to present an in-depth study or a new scientific approach to the dimensioning of rims, which is not discussed in the paper. Only the basic method of modal behaviour of rims is presented.
