5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The manuscript entitled ‘Research on Dynamic Characteristics of Large Deformation Shearer Cable Based on Absolute Node Coordinate Formulation’ applies ANCF（Absolute Node Coordinate Formulation） method to study the dynamic characteristics of cable with large deformation. The topic is interesting and needs to be investigated. For the cables of composite materials and complex structural bodies, the equivalent mechanical parameters are reasonably calibrated by finite element method and tensile test method. A rigid-flexible coupling virtual prototype co-simulation model of the cable dragging system of coal mining machine was established to study the dynamic gradual changes of the cable in different working areas to solve the problem that the actual stress state of the cable in the mine is not easy to obtain, which has some theoretical significance and engineering application value. However，some of the following issues need to be discussed and modified for its improvement.

1.The introduction and chapter 4 mentioned the inability of the conventional finite element method to explain the large deformation motion of the cable, which needs to be briefly explained here in comparison with the current methods for studying such large deformation multi-flexible body dynamics.

2.The names of the industrial simulation analysis software used in the text should be reflected in the text.

3.The latest references need to be supplemented.

4.The English language expression can accurately use the proper nouns of the discipline, but there are also some small errors in word spelling and grammar, please check the context carefully.

5.Please read the PLOS ONE journal's instructions for formatting papers carefully, such as title and abstract， and revise them as required.

Reviewer #2: The research method is innovative and explores the solution of large deformation multi-flexible body dynamics problems in engineering practice. Coal mine explosion-proof requirements, complex occurrence conditions, and severe loads make it very difficult to do experiments on site. The manuscript used the ANCF （Absolute Node Coordinate Formulation）method to simulate the real movement and force state of the cable in the coal mine, which has certain advantages. At the same time, the analysis method of geometrically accurate modeling of the cable and the dynamic characteristic laws of each area of the cable have some guidance for the optimal design of the cable and the arrangement of the coal mining machine cable at the working face. But there are some problems that need to be discussed and modified.

1.There are some minor errors in the format of the references.

2.The expression for cable area delineation on page 14 of the main text should be consistent with that in Figure 15, and the same should be consistent with it in the analysis. For example Area (a).

3. The overall English language expression is fluent and accurate, but there are some small errors in the text, such as on page 14,“ is” repeatedly expressed, and on page 17, “curve ”should be used in the plural form, suggesting that the author should check carefully the spelling and grammatical errors.

4.In the chapter 3.2 of equivalent calibration of cable , for the finite element simulation of the cable, whether the spiral structure of the conductor is retained or the equivalent simplification, please show the specific.

5.In the lower label of Figure 17, the initial letters of the subheadings in (e) and (f) should be kept in line with the previous ones and only lowercase.

Reviewer #3: The object of study in this paper is the dynamic characteristics of the mobile rubber-sheathed flexible cables for coal mines, subjected to complex and severe loads. Unlike the static load of laying cable and the periodic load of submarine cable, its deformation will be large when following the coal mining machine for many short round trips.This manuscript uses the ANCF（Absolute Node Coordinate Formulation） method to better model and analyze the dynamics of the cable with large deformation and realize the simulation of simulated movement.The composite material and complex structure of the cable body make it more reasonable to use a combination of experimental, theoretical derivation and simulation analysis research methods.The research in this paper is useful for the simplification of large-deformation multi-flexible systems and complex structural bodies, and is innovative to a certain extent. However, there are also some problems that need to be discussed and modified:

1.The abbreviation of "Discrete Element Method Multi-Flexible Body Dynamics" in the last paragraph of page 3 should be changed from "EDM-FMBD" to "DEM-FMBD". The manuscript should ensure that the proper nouns and abbreviations of the scientific and technical paper are correct, and it is recommended to double-check other proper nouns.

2.The English language expression is overall more fluent, but there are some minor grammatical errors. On page 16, in analysis (1), the sentence "The cable and the 35th cable clamp..." is not clear enough. On page 17, in analysis (3), the word "perspective" should be used in its adverbial form.

3.In chapter 4.1, the "rodrigues formula" is mentioned in equation 5 for the derivation of the dynamics modeling process of large deformation cables.Please give a brief description of its application.

4.On page 13, why bushings are used between adjacent cable clamps rather than revolute joints? Please briefly discuss the advantages of this choice as well as the rationality.

5.It is recommended to add some updated references from year 2022 and revise the format with reference to the journal’s requirements.
