Reviewer 2 Report

Comments and Suggestions for Authors

The aim of this study is to develop and validate a multi-physical field coupling model using FEM/BEM simulation to analyze the sawing noise radiation characteristics of circular saw blades in woodworking. This work is appropriate for publication in the Forests Journal; nevertheless, there are a few suggestions for the authors to make it better:

 

1- The abstract is unclear, unstructured, and fails to highlight crucial findings. It is overly focused on methods and does not clearly communicate the findings or their relevance.

 

2- I recommend making the figure titles more descriptive and informative to better reflect the content of each figure (Figure 5: "Modal Test; Figure 12: "Noise Directivity", and the same for the Section Title: "4. Test, line 269.

3- I want the authors to pay attention to the values of MOE and MOR for particleboards listed in Table 3.

 

4-the conclusion seems too long and repetitive. A conclusion should stress on key findings concisely, highlight the study's significance, and avoid repeating information already discussed in the results section.

Reviewer 3 Report

Comments and Suggestions for Authors

The authors submitted for review an article entitled: "Modeling the interaction of several physical fields and an experimental study of the characteristics of noise emission from circular saws in woodworking." It is already clear from the title that the article is trying to connect poorly related concepts. How are the physical fields related (by the way, which ones?) and the radiation characteristics? Remarks: 1) In the abstract and introduction, the authors state that the article is a "reliable theoretical basis." Tell me, what does the theoretical basis mean and why is it reliable? I note that the theoretical basis implies a contribution to the theory of the sawing process, as a rule, this is reflected in mathematical models. Have the authors made significant contributions to the mathematical description of processes or to the general theory? It can be seen from the presented material that section 2 has nothing to do with the ongoing research. The mathematical description in section 2 is unrelated and does not have any development in the article. The use of existing modeling tools is not a reliable theoretical basis developed by the authors.

2) In the thermomechanical model, expressions 1 and 2 describe the interaction of a thermal and a force field, but for this it is necessary that the coordinates of one expression be represented in the other and vice versa, but this is not the case. The interaction is not covered here. 3) System 3 has nothing to do with 1 and 2, and there is a gap in reasoning. Question: was this system obtained by the authors? 4) Equation 4 describes the passage: 4.1) It is not specified what does M mean? 4.2) It is not specified how the natural frequency of the saw blade is determined and why the scalar case is considered if the system is described in space. In other words, in which direction is the natural frequency considered? 4.3) It is not described on the basis of which system of equations the eigenvector is calculated. 5) In expression 5, the concept of excitation frequency is introduced, designated in the same way as the natural frequency. Further, according to expressions 6 and 8, this variable denotes a variable frequency external to the system. 6) In the integral 9 T is the duration of the signal, and in 1 it is the temperature. 7) In the results and conclusions, the authors come to obvious conclusions: 7.1) The main source of noise is the sawing process (line 341). 7.2) The distribution of sound pressure depends on frequency (line 357). However, the interaction of physical fields and the effect of this interaction on the sawing process are absent in the results and conclusions.
