Reviewer 2 Report
Dynamic modeling of a flexible-link flexible-joint system with tip mass considering stiffening effect
Dear authors
It is a complete work, which presents valuable results for the scientific community. It has satisfactory results that meet the objectives of the study.
Here are some observations that could improve the content of the study. So that various technological areas understand the importance of your research.
· In the introduction, you can mention the main reason for your study, detail why its development is important, and also mention its possible applications.
· Lines 26 -32. You mention the importance of flexible materials. Here you can expand your explanation by mentioning new trends such as soft exoskeletons and flexible materials. You can be guided by the following article: Soft Exoskeletons:
“Pérez Vidal, A.F.; Rumbo Morales, J.Y.; Ortiz Torres, G.; Sorcia Vázquez, F.d.J.; Cruz Rojas, A.; Brizuela Mendoza, J.A.; Rodríguez Cerda, J.C. Soft Exoskeletons: Development, Requirements, and Challenges of the Last Decade. Actuators 2021, 10, 166. https://doi.org/10.3390/act10070166”
· Lines 56 - 57 - You mention that AMM is preferable to control in real-time. Here you could mention the reasons.
· Figure 4,5,6,7 - Some of the text is very blurry, so it might be a good idea to increase the font size or remove the blur.

Reviewer #1 Comments
- I still believe that the derivation of the dynamics modeling (Eqns. (1)–(26)) may be split further and move intermediate equations into Appendix A.
Response: Thanks for the reviewer’s constructive comment. 19 equations are left in the main context. Other equations in the derivation of the dynamic modeling are removed into Appendix A.
- Equations are now very dense and tightly integrated into the text. White space before/after aligned equations is less than in the previous revision. I recommend increasing the space again for easier readability.
Response: All the equations throughout the paper have been revised with white space for better readability.
We would like to thank again for your constructive comments which help us to improve the paper.
Best Regards,
Lewei Tang
