Dear Dr. Liu,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Mar 20 2025 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org . When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.

We will only publish funding information present in the Funding Statement section of the online submission form.

Please remove any funding-related text from the manuscript and let us know how you would like to update your Funding Statement. Currently, your Funding Statement reads as follows:

“The author(s) received no specific funding for this work”

Please include your amended statements within your cover letter; we will change the online submission form on your behalf.

6. 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.

Additional Editor Comments:

Comments from PLOS Editorial Office: We note that one or more reviewers has recommended that you cite specific previously published works. As always, we recommend that you please review and evaluate the requested works to determine whether they are relevant and should be cited. It is not a requirement to cite these works.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

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: Overview and general recommendations:

This is an article about the application of corrugated structure in impact absorbing advanced support hydraulic pillar. According to the national design standard for advanced support hydraulic pillars, the corrugated energy-absorbing components of the support beams are optimised and their cushioning and energy-absorbing characteristics are investigated. The manuscript is interesting and the reviewer recommends acceptance with modifications. Specifically, the following points should be noted for improvement:

1. The expression of several proper nouns in the manuscript is inconsistent, so please check it carefully. For example, the expressions related to the three energy-absorbing components are inconsistent.

2. In subsection 1.2, it is mentioned that ‘When the reaction force exceeds the initial peak crushing load and after hydraulic support safety valve failures, the deformation displacement is considered effective if the reaction force is less than 1.3 times the initial peak crushing load.’ What is the basis for this, please include necessary explanations or references.

3.The introductory part deals with only about 20% of the references in the last three years, which should be increased appropriately to enrich the study. (Recommended as follows: https://doi.org/10.1016/j.tws.2024.112415

https://doi.org/10.1007/s43452-024-00895-9

https://doi.org/10.1016/j.engfracmech.2024.110009)

4. Figures 3.2 and 3.3 seem to lack the necessary textual descriptions in the manuscript; moreover, the titles of the figures are inconsistent with the contents of the figures (e.g., energy absorption vs. specific energy absorption in Fig. 3.2; relative energy absorption vs. specific energy absorption in Fig. 3.2).

5. The curves in Figure 4.8 are interesting and, unlike the other two structures, the reader may expect a more in-depth analysis.

Reviewer #2: The paper has produced some meaningful results, but there are still many issues that need to be revised.

1. The structural layout is not good enough and the readability is poor.

2. Innovation needs to be emphasized. Is it just a matter of different application scenarios? Is there any innovation in the corrugated structure itself?

3.The ANSYS version should be provided. I didn't see the introduction and steps of calculation by using ANSYS in the article, please provide detailed information.

4.What is the purpose of the experiment listed in the article, and is it to verify the calculation results? I did not see the verification process and results. If it's not for verification, is it using experiments as a means of research? So what is the connection with the previous calculation, and what is the logic behind putting it into a paper?
