A Rotational Order Vibration Reduction Method Using a Regular Non-Circular Pulley

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors The paper is very interesting. I am not clear on several aspects related
to the experimental results: how the input excitation was obtained and
how the phase shift between the excitation and the variation law of
the elliptical profile was varied;
are the graphs in figures 19 and 20 purely theoretical or experimentally validated. Comments on the Quality of English Language Some sentences are not formulated correctly. It is recommended to have it checked by a person familiar with English.

Comments and Suggestions for Authors

1. Some symbols in this research need to present the meanings, otherwise, it will affect the readers' reading experience. Besides, the layout of the paper is very poor.

 

2. During the process of model establishment (Eq. (1)-Eq. (17)), the Ref. [22] is the main reference source. Will it cause repetition? If so, the derivation process can be simplified.

 

3. The quality of the diagrams in the research is poor. It is recommended to enhance their accuracy and expressiveness.

 

4. To thoroughly review the most recent results on bio-inspired vibration isolation system, the authors should cite literatures from the last several years.

Comments and Suggestions for Authors

The paper deals with using a method with a regular non-circle active pulley to counteract the regular order excitation and the regular load excitation in the transmission systems. The toothed belt drive system with second-order excitation is taken as an example. According to the existing analytical model of the tooth belt drive system, the modeling process and analytical solution algorithm of the system are derived. The experimental verification is carried out. The method can provide new ideas for the vibration reduction optimization process of systems with primary order wave excitation.

The paper contributes to the knowledge base. The paper is written in an appropriate way.

I do not suspect the authors of plagiarism, fraud or other ethical concerns. The English language is understandable but should be partially improved.

 

Specific comments on the paper are given below.

 

Comments:

1. The label “Figure 5” is used twice in the paper for figures. In addition: Caption of the first Figure 5: Write “Figure 5.” in bold letters and write dots “.” after “5.” and after the caption.
2. Equation (13): The meaning of torque “Mf” is not introduced.
3. Equation (17): The meaning of angle “alpha t” is not introduced.
4. Line 238: Horizontal axis X is not shown in Fig. 4.
5. Equation (27): “d phie” should be after the square root and write “d” in Roman letter.
6. Equations (31) and (32): It is not clear how these equations were arrived at. Or it is not referred to where they were taken from.
7. Figure 8: In the label of the horizontal axis should be “min-1” (i.e. “-1” is missing).

 

Formal comments:

1. Unify writing references to Figures with “Figure” or with the abbreviation “Fig.”.
2. Unify writing references to Equations with “Equation” or with the abbreviation “Eq.”.
3. Unify writing references to Sections with the small first letter “s” or with the capital first letter “S”.
4. Use the multiplication sign “·” in all relevant cases instead of the dot “.”.
5. I recommend unifying the writing of physical units for speed “rmin” or “r/min”.
6. Line 24: Write “Experimental” with the small first letter “e”.
7. Subchapter 1.2: Do not write the first names of authors nor their abbreviations in references to literature.
8. Line 85: Write “drive” instead of “dirve”.
9. Equation (3), lines 177, 217: Write “psi” in italics.
10. Line 130: Write “sigma” in italics.
11. Line 136: Write “friction” instead of “frictin”.
12. The caption of Figure 2: Write “Figure 2.” in bold letters and write dots “.” after “2.” and after the caption.
13. Figure 7: In the label of the vertical axis write “Oscillation” instead of “Oscilaltion”.
14. Figure 11: In the label of the vertical axis write “Oscillation” instead of “Osciilation”.
15. Figure 12: In the labels of the vertical axes write “Tensioner” instead of “Tenisoner”. (2 times)
16. The caption of Figure 12: Write “Figure 12.” in bold letters and write dots “.” after “2.” and after the caption.
17. Figure 15: In the label of the vertical axis of the right graph write “Fluctuation” instead of “Flutuation”.
18. The caption of Figure 15: Write “Figure 15.” in bold letters and write dots “.” after “2.” and after the caption.
19. Figure 17: In the label of the vertical axis of the right graph write “Fluctuation” instead of “Flutuation”.
20. The caption of Figure 17: Write “Figure 17.” in bold letters and write dots “.” after “2.” and after the caption.
21. The caption of Figure 19: Write “Figure 19” in bold letters and write dots “.” after “2.” and after the caption.
22. Figure 20: Write “Case II(Elliptical ” instead of “Case II(Ellitical ”.
23. The caption of Figure 20: Write “Figure 20” in bold letters and write dots “.” after “2.” and after the caption.
24. Table III: Remove dot “.” after the second “orientation”.
25. References: Write all references to the literature in compliance with the requirements of the Actuators.
