Mechanical Behavior of Crimping Composite Post Insulator: Experimental and Simulation Study

Round 1

Reviewer 1 Report

1.         It is necessary to use the traditional scheme of the manuscript (Introduction, Materials and methods, Results and discussion, Conclusion).

2.         Correct the word "comp006Fsite" (line 34).

3.         Decipher the abbreviation MPC.

4.         Check the captions of the figures 1, 2, 5, 6, 10, 11.

5.         Provide a reference to the literary source for the data in Table 1.

6.         Check that all parameters in formulas (1) – (5) are described in the text.

7.         It is recommended in section 1.2. Finite element model to describe in more detail the finite element mesh (type of elements, size of elements). How were the calculations carried out in the ANSYS program?

8.         It is recommended to add a sketch and a photo of the testing stand in section 1.3. Experimental verification of statics. Specify the location of sensors and the direction of action of the load.

9.         Describe in more detail how the results are obtained in Figure 8. Since section 2.2 describes the calculation of natural frequencies.

10.       In section 2. Optimization Design of Flange Structure Parameters, it is necessary to add mechanical requirements to the insulators. To compare the obtained calculation results with the design requirements.

11.       In the text, it is necessary to discuss the practical significance of the obtained results in the design of post insulators.

12.       How is the continuation of this work planned? For example, the use of other pultruded materials for mandrel.

Reviewer 2 Report

In the reviewed paper, the Authors proposed a finite element simplified model of crimped composite post insulator based on Multi-Point Constraints, which simulates the crimping area of mandrel and flange in engineering practice. It verifies the model's reliability through static tests and characteristic vibration tests. The results show

that the difference between the finite element simulation and test results is within the error border. In my opinion, the paper can be considered for publication, after taking into account the following remarks:

- is like follows "0. Introduction", should be like follows "1. Introduction",

- before paper publishing the paper text needs carefully checking by a professional Native Speaker,

- in the keywords section, a keyword connected with "Buildings" should be also added,

- at the end of the Introduction section, the Authors should add a short information what was the main aim of the paper as well as what was contained in each paper section,

- there is a lack of section (usually it is section number 2) dedicated to a literature review on the subject presented in the paper,

- equations (1), (2), (3), and others: there is a lack of explanation of used variables/acronyms in the equations,

- the title of the figures did not precise the figure content, e.g. "Figure 3. Cantilever", but what cantilever?

- "Figure 8. The mandrel under a horizontal tension of 4.5 KN"- the legend is too small and because of it difficult for reading,

- there is a lack of discussion in the paper dedicated to the presented optimization design of flange structure parameters,

- is like follows "3. Conclusion", should be like follows "3. Conclusions",

- the conclusions section is poor in content and should be developed by adding some detailed conclusions from the presented in the paper research.

 

Before paper publishing the paper text needs carefully checking by a professional Native Speaker.

Reviewer 3 Report

Dear Authors,

Very interesting article, but please correct minor errors:

- please add this experimental research methodology,

- please describe more clearly the data selected in the numerical analysis,

- introduce a table with the differences of experimental, theoretical and numerical results,

- enter photos from experimental studies.

Minor editing of English language required
