On the Efficacy of a Novel Optimized Tuned Mass Damper for Minimizing Dynamic Responses of Cantilever Beams

Round 1

Reviewer 1 Report

The followings should be addressed to improve the quality of the paper:

 

1.  The contributions of this paper should be highlighted in introduction.

2.  It is better to list the parameters of the TMD as a table.

3.  Please check the sub-icon number carefully, for example, Figure 11.

4.  In section of numerical example, some comparisons should be made to show advantages of the proposed scheme in this paper.

5.  The reference should be updated, and some relevant references should be covered to enrich the literature review. In addition, the format of the references should be checked and modified.

6.  English writing should be further polished.

Reviewer 2 Report

This paper studies the vibration control of a cantilever beam using tuned mass damper. The following issues should be addressed before it can be recommended for publication.

1. The novelty and motivation of this paper are not clear. There are a lot of studies on vibration control using tuned mass damper. What is the new finding of this paper? The optimization of TMD is also well understood. Why is it important to optimize the TMD parameter using the Differential Evolution optimization algorithm.

2. Fig 1 needs more explanation. The total energy dissipated in (b) is higher than that dissipated in (a).

3. It is suggested to compare the present optimization method with existing methods or design formulas.

 

4. It is suggested to include some recent advances on TMD optimization, e.g., Tuned mass damper for self-excited vibration control: Optimization involving nonlinear aeroelastic effect.

Reviewer 3 Report

The paper "On the Efficacy of a Novel Optimized Tuned Mass Damper for Minimizing Dynamic Responses of Cantilever Beams" reports a study about the optimum design of TMD in a frequency domain considering cantilever beams. The manuscript appears well-organized in its different sections and the approach proposed by the authors is clearly described in the text. Furthermore, the results obtained from the numerical example reported in Section 4 are adequately presented, highlighting the original aspects of the method proposed. For these reasons it is opinion of this reviewer that the manuscript can be considered for the publication in applied sciences journal after the following minor correction/improvements;

-        Figure 2 and 3: improve the quality with particular attention to the cross section.

-        Line 299: the sentence “Figure 3 shows the six-node finite element cantilever beam with a TMD” is a repetition than that reported in lines 289-290.

-        Improve the quality of the legend of the Figures 7-10.

-    In the introduction add some references which highlight the use of TMDs in structures characterized by cantilever behaviour as reported in 10.1016/j.istruc.2021.02.053, 10.1002/tal.1068, 10.1016/j.engstruct.2016.06.006

-        In the conclusions, add the future developments of the work.
