Fractional Modeling and Characteristic Analysis of Hydro-Pneumatic Suspension for Construction Vehicles
Round 1
Reviewer 1 Report
The research design is appropriate. The methodology is very well explained. The title of the paper reflects its content.
The document must be checked as there are inaccuracies and style errors.

Reviewer 2 Report
Overall comment:
The reviewer finds the article well written and structured, and no major comments are considered. However, the authors must revise tome typos in the paper and correct other minor comments listed below.
Minor comments:
- Include a final paragraph in the introduction to describe the structure of the paper.
- Unify the references to figures: sometimes they are referred as Fig. X, and others as Figure X.
- There are some typos to correct:
- Abstract: char-
- Introduction, 1st pragraph: hy-dro-pneumatic (2 times).
- Introduction, 3rd paragraph: pa-rameters and hy-dro-pneumatic.
- Section 2.2, 1st paragraph: neglect → neglected, studied., → studied,
- Section 2.2, 2nd paragraph: “between the piston rod and the piston assembly and the cylinder barrel is required.” → replace the first “and” with a coma.
- Page 6, 3rd paragraph: “damped vibration equation system [16], After sorting…” → replace the coma by a point.
- Conclusions, 2nd paragraph: equa-
- Conclusions, 3rd paragraph: frac-tional-order model, im-
- Introduction: indicate the number of reference of Michele and Gao, SunTao et al. and Wang Hanping.
- Section 2.1 after equation (1): the Greek letter that refers to the integral variables is not the same in the equation and the later explanation.
- Write : in the line before presenting the equations.
- Section 2.2, 1st paragraph, last sentence: I believe it is not well written, there must be any verb or linker missing.
- Page 5 after equation (5): use only one -.
- Page 6, 1st paragraph: write the equation in math environment.
- Section 3, 1st paragraph, last sentence: I believe it is not well written, there must be any verb or linker missing.
- Suppress the last part of the conclusions, where it says “6. Patents”.

Author Response
Point 1: Include a final paragraph in the introduction to describe the structure of the paper.
Response 1: I have added a paragraph to the introduction as required to describe the structure of the paper.
Point 2: Unify the references to figures: sometimes they are referred as Fig. X, and others as Figure X
Response 2: I have modified as required to use "figure X" uniformly
Point 3: There are some typos to correct:
Abstract: char-acteristics.
Introduction, 1st pragraph: hy-dro-pneumatic (2 times).
Introduction, 3rd paragraph: pa-rameters and hy-dro-pneumatic.
Section 2.2, 1st paragraph: neglect → neglected, studied., → studied,
Section 2.2, 2nd paragraph: “between the piston rod and the piston assembly
and the cylinder barrel is required.” → replace the first “and” with a coma.
Page 6, 3rd paragraph: “damped vibration equation system [16], After sorting…” → replace the coma by a point.
Conclusions, 2nd paragraph: equa-tion.
Conclusions, 3 rd paragraph: frac-tional-order model, im-provement.
Response 3: I have corrected the above spelling errors as required, please refer to the paper revision mode for details
Point 4: Introduction: indicate the number of reference of Michele and Gao, SunTao et al. and Wang Hanping.
Response 4: Michele [1] and Gao [2] have modeled and simulated the active hydro-pneumatic suspension of heavy vehicles, Sun Tao et al. [3] established a long-hole turbulence damping model of a hydro-pneumatic suspension and simulated its stiffness and damping characteristics, Wang Hanping [4] conducted a modeling study based on the theory of heat transfer.
Point 5: Section 2.1 after equation (1): the Greek letter that refers to the integral variables is not the same in the equation and the later explanation.
Response 5: The Greek letters in the explanation have been corrected.
Point 6: Write: in the line before presenting the equations.
Response 6: I have modified as required
Point 7: Section 2.2, 1st paragraph, last sentence: I believe it is not well written, there must be any verb or linker missing.
Response 7: I have modified the last sentence as follows. The same instantaneous pressure is equal everywhere in the enclosed area under study.
Point 8: Page 5 after equation (5): use only one -.
Response 8: I have modified to use only one-.
Point 9: Page 6, 1st paragraph: write the equation in math environment.
Response 9: I have writen the equation in math environment.
Point 10: Section 3, 1st paragraph, last sentence: I believe it is not well written, there must be any verb or linker missing.
Response 10: I have modified the last sentence as follows. A number of sensors such as displacement, acceleration, tension and pressure are installed to test the output characteristics of the hydro-pneumatic suspension when subjected to external excitation and load.
Point 11: Suppress the last part of the conclusions, where it says “6. Patents”.
Response 11: I have deleted “6. Patents”
