Analysis of the Mechanical Properties and Study of Influential Factors of Different Materials in Tape Spring

Round 1

Reviewer 1 Report

This paper use ABAQUS to simulate the mechanical properties of composite   laminated tape springs. Minor issues need to revise in the manuscript. 

3.Numerical Analysis

In figure 10, The author should discuss the reasons why the composite material spring  is better than the ordinary spring and the negative Poisson ratio honeycomb  structure spring. 

Figure 12 results should explain more contents or chart to explain the maximum stress values for different type of structure.

 4.conclusions

Suggest use 1,2,3 listed the important finding. The reader will easy to know the conclusion for this paper.

Reviewer 2 Report

This work is certainly interesting and has important potential consequences. But the manuscript needs the following modifications:

1.      Page 10, Line 170 (Figure 8): Authors are recommended to add the units of the reciprocal of curvature radius, and the composite springs ply thickness.

2.      Page 10, Line 176 (Table 3) and Line 177 (Table 4): Authors are recommended to add the units of ply thickness, steady-state bending moment, critical bending moment and central angles.

3.      Also, authors are recommended to add the units for the different parameters in Table 5 (Page 11, Line 190).

4.      It is recommended to improve the resolution of figures specially Fig. 7 (Page 9, Line 167) and Fig. 10 (Page 11, Line 188).

5.      Authors are recommended to discuss more the “Numerical Analysis” section to clarify and highlight research findings.

The manuscript is well organized and is easy to read and comprehend

Reviewer 3 Report

This is an article that fits within the scope of this Journal. The significance of this paper is reflected in attempt of research team to analyze mechanical properties of tape spring structures with different structures and materials, optimize the design of tape spring structures, and seek the optimal mechanical performance of tape spring structures. However, to my point of view, there are several points that need to be addressed prior to publication. Terminology as well as language is acceptable, but text improvement is necessary.

 My comments/suggestions are given hereafter:

• In the chapter 1 provide better visibility of the Figure 1.
• My suggestion is to put under each figure only numeration (a) and (b) and in the Figure title you can put as following: Figure 1. Assembly diagram, of solar panel: a) CubeSat System with main units, b) CubeSat System with exploded parts. This suggestion is because you have position from A to M on the figures too.
• Maybe to expand introduction with some results achieved in previous study. i.e. ref. [15].
• On the page 4, numeration on Figures 5 and 6 should be done following suggestion above (for Fig. 1). For example, on the Figure 6 you didn’t explain in the figure title what is on (a) and (b).
• It needs to be better defined finite element model in term of type of used elements, number of elements and nodes. The boundary conditions should be shown on some figure of finite element model if possible!
• The maximum stress values given in lines 212 and 213 weren’t discussed precisely.    
• General suggestion is to improve discussion on finite element numerical analysis – Chapter 5!

I encourage you to resubmit the paper with all necessary corrections and improvements.

Minor editing of English language required as well as text formatting in terms of type and size of used font.

Round 2

Reviewer 3 Report

I suggest you some corrections in order to improve this paper in term of text formatting like:

1) Figure 6 overlap down part of the table 2.

2) Text starting from the line 263 drop a little below table 6.

3) check and if necessary do renumbering of the equations
