3. Thank you for stating the following financial disclosure: 

   "This work was supported by the National Natural Science Foundation of China ( 51874158 ), the National Natural Science Foundation of China Youth Science Foundation ( 51904142 ), "

Please state what role the funders took in the study.  If the funders had no role, please state: "The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript." 

If this statement is not correct you must amend it as needed. 

Please include this amended Role of Funder statement in your cover letter; we will change the online submission form on your behalf.

4. We note that your Data Availability Statement is currently as follows: All relevant data are within the manuscript and its Supporting Information files.

Please confirm at this time whether or not your submission contains all raw data required to replicate the results of your study. Authors must share the “minimal data set” for their submission. PLOS defines the minimal data set to consist of the data required to replicate all study findings reported in the article, as well as related metadata and methods (https://journals.plos.org/plosone/s/data-availability#loc-minimal-data-set-definition).

For example, authors should submit the following data:

- The values behind the means, standard deviations and other measures reported;

- The values used to build graphs;

- The points extracted from images for analysis.

Authors do not need to submit their entire data set if only a portion of the data was used in the reported study.

If your submission does not contain these data, please either upload them as Supporting Information files or deposit them to a stable, public repository and provide us with the relevant URLs, DOIs, or accession numbers. For a list of recommended repositories, please see https://journals.plos.org/plosone/s/recommended-repositories.

If there are ethical or legal restrictions on sharing a de-identified data set, please explain them in detail (e.g., data contain potentially sensitive information, data are owned by a third-party organization, etc.) and who has imposed them (e.g., an ethics committee). Please also provide contact information for a data access committee, ethics committee, or other institutional body to which data requests may be sent. If data are owned by a third party, please indicate how others may request data access.

5. PLOS requires an ORCID iD for the corresponding author in Editorial Manager on papers submitted after December 6th, 2016. Please ensure that you have an ORCID iD and that it is validated in Editorial Manager. To do this, go to ‘Update my Information’ (in the upper left-hand corner of the main menu), and click on the Fetch/Validate link next to the ORCID field. This will take you to the ORCID site and allow you to create a new iD or authenticate a pre-existing iD in Editorial Manager. Please see the following video for instructions on linking an ORCID iD to your Editorial Manager account: https://www.youtube.com/watch?v=_xcclfuvtxQ

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 study addresses an important problem, and it contains an interesting and in-depth mathematical, experimental and simulation analysis regarding stability during cutting process of the boom-type roadheader. The authors have collected a unique dataset using cutting edge methodology. Hence, the proposed method in this paper can be useful precursors of further progress in this field. Overall, the manuscript is well thought out and written, the objectives clearly stated, applied methods are advanced, data statistically analyzed, the conclusions well supported by the data presented. The reviewer recommends its acceptance after considering some relatively minor corrections/clarifications improving the clarity of presentation as follows:

1. The article is based on the vibration data under steady cutting condition as input and output signals, and further explanation on the selection of working conditions is suggested (smooth working conditions are used in the theoretical analysis part, and extreme working conditions are used in the fatigue analysis part). The author needs to unify the working mode of manuscript research.

2. The specifications of the accelerometer are missing. Please check.

3. The manuscript carried out response surface optimization for the rotary table ; considering that the number of initial optimization parameters is large and the number of multi-objective optimization samples is complicated, it is suggested that the author carry out parameter sensitivity analysis before optimization.

4. Manuscript references need to be further standardized ; it is suggested that the author unify the reference format of the manuscript to meet the requirements of the journal format.

Reviewer #2: By establishing a spatial mechanical model of the cantilever roadheader, the variation law of the load at the hinge ear of the rotary table is obtained; Based on the analysis method of working condition path transfer, establish a model for analyzing the working condition transfer path of the rotary table, simulate the vibration of the rotary table during the cutting process, and determine the main vibration source of the rotary table; Furthermore, the correctness of the theoretical model was verified through cutting experiments; Finally, finite element analysis combined with response surface optimization was used to optimize its structure, improve the service life of the rotary table and enhance its operational stability.

1.under ideal conditions, the rotary table can run for 10.45 years. Not 10.6!

2.it can be seen from the curve results that the maximum positive amplitude of the turntable is not 3.4751mm!

3.the hinge ear B2 under the rotary table is greatly affected by the vibration of A4 and A5 excitation points. Not A3 and A5!

In addition, it is not that A3 and A5 lack explanations for maximum stress I1 and maximum strain I2.

4.in the finite element analysis section, the location of adding boundary conditions is not shown in the image.

5.only solve the fatigue life of the turntable under symmetric cyclic loading; Lack of research under irregular load conditions.

6.for the sake of consistency, replace "turntable" with "rotary table" in the title of Table 1.

7. Missing keyword section, formula not centered, paragraph not indented on first line, and formula numbers is chaotic.
