Research on Material Viscoelasticity and Its Influence on Indentation Rolling Resistance
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors present results regarding the influence of viscoelasticity on indentation rolling resistance. However, the quality and coherence of the text require improvement.
Some sentences lack context, making it challenging to discern the authors' intended message. An introductory section explaining the core concepts of the problem would enhance clarity. Additionally, there shouldn't be a distinction made between foreign and domestic research; all relevant work should be integrated seamlessly.
Furthermore, equations should be properly introduced (with references to other works) to facilitate evaluation of the manuscript.
While the work may have potential for publication, significant reformulation of the manuscript is necessary to meet publication standards.
Comments on the Quality of English Language
The text must be thoroughly revised. There are several confusing sentences, and plenty of typos can be found along the text.

Title: Research on Material Viscoelasticity and Its Influence on Indentation Rolling Resistance.
This paper presents a study on the characterization of a viscoelastic material model and its influence on indentation rolling resistance. However, some problems must be addressed and corrected by the authors for the paper to be accepted for publication:
1) Drums and rollers are distinct components of a belt conveyor. Therefore, there should be a slight correction in line 38.
2) All the information described in lines 39 to 45 needs references
3) Correct sentence on line 44.
4) At the end of the Introduction section, from line 45 onwards, the statements need further explanations, references and corrections for a better understanding of the justification for the article's proposal, which should be explicit in this Introduction section and not in the Related Studies section.
5) In the Related Studies section, all references only mention the first author. The second author should be referenced and "et al." should be used for more than two authors.
6) Also in the Related Studies section: In descriptions of domestic research, the emphasis should be on the findings and not on the software used in the studies.
7) Explain the text in lines 89-90. The statement about the use of the model in the specific situation is confusing. What specific situation?
8) You cannot start a section (subsection 3.1) with a figure. There should be an introductory text about what the section is about and then mention figure 1 in the text before presenting it.
9) Rewrite the equations by adjusting the size of the variables and exponents. The exponents are difficult to understand. Improve the technical rigor of the descriptions of the variables in the equations.
10) Correct the logarithm symbol throughout the text. It is not "lg".
11) In Table 1, is it necessary to have all the decimals shown?
12) Line 292: the word "where" should not start paragraphs when the text is explaining meaning of variables in an equation.
Comments on the Quality of English LanguageSome sentences in the text need corrections for a better understanding, according to comments and suggestions to the authors.

Reviewer 3 Report
Comments and Suggestions for AuthorsThe paper discuss the relaxation characteristics of viscoelastic materials.
Some comments:
1.The author discusses the generalized Maxwell model and claims it is not unique. It is correct. However, the generalized Maxwell model is for modeling the time-depedant behavior of viscoelastic materials in the real world applications. For example, in stress-strain analysis, the response of viscoelastic materials is usually lower than pure elastic materials. Thus, the prony constants do not have to be theoretical unique. It just needs to be a good approximation for real world applications. Moreover, the author has not proved the uniqueness of your model.
2. The key of characterization of viscoelastic materials is to capture the glass transition region, the second stage of creeping, the transition and final stage of stress relaxation. The author has not discussed about this.
3. The author proposes some models of viscoelasticity, but the experimental validation should be included.
4. There are no units for figure 2-6. The format of figures are not consistant. The author should pay more attention on paper writing.
Comments on the Quality of English Language
The paper is hard to follow. Please improve the language.

It just needs to be a good approximation for real world applications. Moreover, the author has not proved the uniqueness of your model.
Response 1: Thank you for your comment. The core of my paper is to prove that the 2N+1Maxwell model is affected by the test time interval, so the 2N+1 model with limited test time interval is correct, and the conclusion is that the 2N+2 model is not affected by the test time interval and is more universal.
I added” A Maxwell model of 2N+1 element within a specified testing time range is correct and unique“ in line 127 and “because the 2N+2 Maxwell model does not impose restrictions on the testing time range” in line 153.
Point 2: The key of characterization of viscoelastic materials is to capture the glass transition region, the second stage of creeping, the transition and final stage of stress relaxation. The author has not discussed about this.
Response 2: Thank you for your review. The focus of this paper is to analyze the expression of relaxation modulus of viscoelastic materials under Maxwell model. Creep compliance is not the focus of this paper, and some stages such as glass state in relaxation stage are mentioned in the part of indentation rolling resistance, but it does not seem to be the focus of this paper.
In the introduction part, I have revised the lines from 46 to 60 to make readers better understand the core work of this article.
Point 3: The author proposes some models of viscoelasticity, but the experimental validation should be included.
Response 3: Thank you for your review. Several models I proposed are ideal models of virtual materials, so I only did simulation analysis, and the experimental part of real materials is my last paper published in this journal, which introduced the design of experimental device and the measurement of relaxation modulus, which is not the focus of this paper.
I added” The proposed relaxation time spectrum models are all virtual ideal spectral lines, so this section presents simulation and analysis of only these ideal materials. The relaxation spectra of these ideal virtual materials are regular, whereas the relaxation spectra of real materials typically demonstrate irregular variations. Therefore, the experimental testing on real materials is not the primary focus of this study“ in line 185.
Point 4: There are no units for figure 2-6. The format of figures are not consistant. The author should pay more attention on paper writing.
Response 4: Thank you for your review. I have added the units in Figure 2 to Figure 6, and changed the format of all the pictures to be unified.
Point 5: The paper is hard to follow. Please improve the language.
Response 5: Thank you for your review. I have polished all the sentences in this article under the guidance of my English teacher.
