The Analysis of Stiffness and Driving Stability in Cross-Member Reinforcements Based on the Curvature of a Small SUV Rear Torsion Beam Suspension System
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsAuthors presents research about the influence of reinforcements added to small SUV real torsion beam suspension system on stiffness and ride comfort.
The paper must enlarge the state of the art and including more recent references related to low weight vehicles and the evaluation of their ride comfort (ie: bicycles, e-scooters, and so on). At least 10-15 reference more are needed. Only 11 references are more indicated for congress papers.
The ride comfort in vehicles must be sound justified and explained the method used. In vehicles is used standard ISO-2631 and in railway, UNE12299 based on ISO2631.
Results should also be discussed with other ride comfort analysis.
I recommend that the paper should be rewritten and resubmitted after a deep review.

Analysis of Stiffness and Ride Comfort in Cross-member Reinforcement Based on the Curvature of a small SUV Rear Torsion Beam Suspension System
The article is dedicated to a very important issue in the area of the automotive industry, i.e. the study of suspension systems. The authors had added various shapes of cross member reinforcements to the existing torsion beam suspension and they analyzed the structural strength when subjected to arbitrary forces. For this purpose, analysis results were obtained for stiffness and ride comfort evaluation factors such as SRS, impact hardness, and memory shake. Owing to the obtained results the Authors found the optimal cross-member shape.
Due to the importance of the automotive industry for the development of the entire economy, the subject matter of the article is very interesting both from a scientific and practical point of view. It also seems that the article will be of interest to readers of the journal Applied Sciences.
The structure of the work is appropriate.
In the introduction, the authors presented some information about the research on suspension systems. I think authors should try to find more papers/documents concerning their research area
The method proposed by the Authors was presented clearly.
The drawings are generally legible and of good quality.
The experiments were properly planned and carried out.
My comments and recommendations relating to the manuscript are following:
- There are only 11 items in the literature. I don't think that's enough. In addition, the cited items come from practically one country. It would be worthwhile to try to find materials from non-Korean authors.
- In the abstract, the authors use the term "domestic". The journal "Applied Sciences" has an international reach, so the word "domestic" is inappropriate here.
- Table 1 – the unit of Young modulus should be GPa not „Gpa”.
- The values in Figure 6 are difficult to read
- Table 8 – all values in the table are the same, so I would suggest removing this table and providing these values in the text of the manuscript.
- Figure 9 – the diagrams in both drawings are very similar. I would suggest generating a diagram that would show the difference between the values obtained for the left and right wheels
- Fig. 11 – similar comment as this given to Figure 9.

Reviewer 3 Report
Comments and Suggestions for AuthorsThis paper discussed about stiffness and ride comfort in cross-member reinforcement based on the curvature of rear torsion beam suspension system. The manuscript is also well-written. However, some mistakes are found that should be clarified. My comments are listed below.
1. Table 1: The Young’s modulus value is too small. If you used this value, recalculation is required.
2. P of Pascal should be written in capital letter. Please check.
3. Type 4 has lowest bending stress and highest torsional stiffness. Authors should explain the reason in Discussion.
4. Type 1 has smallest SVSA angle. Authors should explain the reason (mechanism) in Discussion.
5. In the real situation, the loading condition is dynamic loading. However, some simulations were conducted under static condition. How can you be sure that the result will not change under dynamic loading condition? Please explain.
6. The difference of SVSA between type 1 and 4 is very small (less than 0.1). Can you explain the effect of 0.1 difference in SVSA on driver perception?

Round 2
Reviewer 1 Report
Comments and Suggestions for AuthorsAuthors have improved the paper in relation with the references of the state of the art.
However, the ride comfort is different than the a “stable ride”, the title does not respond to the presented research: “Analysis of Stiffness and Ride Comfort in Cross-member Reinforcement Based on the Curvature of a Small SUV Rear Torsion Beam Suspension System”.
I recommend to deeply change the paper clarifying the paper in this regard (also the title).
Also, results should be discussed with other similar research (stability of riding, not ride confort).

Comments and Suggestions for AuthorsAuthors have changed adequatelly the title and the use of "ride comfort" along the paper.
Now, the paper falls in a coherent research.
