Modeling of Acoustic Vibration Theory Based on a Micro Thin Plate System and Its Control Experiment Verification
Round 1
Reviewer 1 Report
This work focuses on the modeling of acoustic vibration theory and the single particle motion control technique. It is interesting. Figs. 1, 2 are not clear enough, it is better to make them clearer.

Reviewer 2 Report
1. The experimental section is not presented very clearly. I think the authors should add some details on the experimental setup.
2. The English of the paper needs to be corrected. There are many prepositions missing in the document
3. A separate discussion section may be added. Highlighting the main contribution of the results as compared to the previous research.

Reviewer 3 Report
The article deals with the modeling of acoustic vibrations based on a microfine plate system. Mathematical modeling, numerical and experimental studies of a thin plate were carried out. The material of the article deserves attention. But despite this, there are provisions in the article that do not disclose very important issues. There are also statements that are difficult to agree with or that require additional explanation. This is described below.
Abstract.
The abstract reveals the general content of the article, allows you to understand what area the work is devoted to. The main provisions of this article are indicated.
1. Introduction
In the introduction, the authors share the history of research on the distribution of micro-nanoparticles under the influence of an acoustic wave. It is indicated that there are difficulties in the process of numerical modeling of the continuous medium of propagation of acoustic waves and therefore it is proposed to discretize it into finite elements. The use of the Comsol software package for the numerical study of a square micro silicon thin plate is justified. The section ends with a paragraph of annotation of the content of the following sections, which is not appropriate, because there is a separate section for this. In addition, the problem that the authors propose to solve is not explicitly indicated.
2. Theoretical analysis of thin plate vibration
In the second section, the authors conduct mathematical modeling of a square micro silicon thin plate. As a result of mathematical analysis, the authors propose a function for responding to the vibration of a thin plate in combination with the Greene function. At the same time, it is not clear what limitations exist for a mathematical model? Is it possible to apply the results to plates with another material, what sizes of the plate are permissible?
3. Finite element simulation analysis
The third section is devoted to numerical modeling of a thin plate in the Comsol Multiphysics software package. The authors do not specify the type of modeling grid used, its number of cells. It is not clear how the optimal conditions for the grid were determined? It is known that the stability and convergence of the calculation depend on the listed characteristics of the grid. Moreover, the authors did not specify the number of iterations that allowed to obtain the convergence of the calculation. Analyzing the data presented, one cannot say with certainty about good coordination.
4. Experimental results
In the fourth section, the authors conduct an experiment with the vibration mode of a thin plate. The figures show the experimental setup as well as the results. The authors point out that: «The experimental results are obtained corresponding to the numerical analysis results in section 3 by Comsol Multiphysics within a reasonable error range». However, it is not indicated within what limits? How can this be analyzed? Moreover, there are doubts about the frequency of the experiment, because the authors do not indicate the number of experiments, as well as what is the error between experiments? If only one experiment was conducted, the results cannot be considered credible.
Further, the authors say: «The experimental vibration modes in Fig.11 correspond well with the simulation results in Section 3 and become more and more complex as the frequency gets higher». However, on what basis did the authors make this statement? How well do the results of numerical and experimental studies agree?
5. Conclusions
The final section contains provisions that are usually described in the initial sections of the article, for example, in the abstract and in the introduction. The results obtained by the authors are not explicitly given. The current section does not allow us to assert that these are the conclusions of a scientific study, it should be said that this is just a brief summary.

Round 2
Reviewer 3 Report
1. In numerical modeling, there is the concept of mesh convergence. The study of mesh convergence is carried out in order to establish the optimal number of cells. Therefore, any CFD calculation should be based on mesh convergence. This is an integral part. I recommend that you study this issue. For example, here is an article: https://www.researchgate.net/publication/321665096_Case_Study_of_Laser_Hardening_Process_Applied_to_4340_Steel_Cylindrical_Specimens_Using_Simulation_and_Experimental_Validation. Figure 4 (b) shows a graph of the mesh convergence of the calculation.
2. In scientific research, a comparison is usually made between the results of experimental and numerical studies. I can see that visually the results converge. However, despite this, the error can be large. Therefore, usually show the percentage of convergence of numerical and experimental results, graphs are given for comparison.
I ask you to take note of these provisions.
