Experimental Investigation of the Dynamic Response of a Sliding Bearing System under Different Oil Pressure Levels
Round 1
Reviewer 1 Report
In this paper, the system response of rotor test benches simulating single-rotor and two-rotor systems with different rotational speeds and oil pressures under various operating conditions is experimentally investigated. Also, the relationship between dynamic response and oil pressure conditions was investigated. The study is innovative in these aspects.
1- Absract should be rewritten more clearly and the results should be emphasized in the other section.
2- In the 2nd part, the error text about the figure source is available in the text.
3- References should be given to generally accepted statements. Like the Poincare cross-section map...
4- In Figures 8 and 9, figures related to different angular velocities and power spectrums can be shown with a single graphic. The comparison is more easily seen by the reader.
5- Section 3.1.2. It is not clear what (e) and (f) below define.
6- Figure 10 should be explained in detail in the text.
7- What is the difference between Figure 10 and Figure 11 and 12?
8- Figures 17 and 18 titles are the same. Why is it repeated? These titles should be corrected.
9- No Table available? With the table, the results can be stretched to compact.
8- Figures 21 and 22 titles are the same. Why is it repeated? These titles should be corrected.
10- In the conclusion part, the calculation method and the test device are mentioned.
This part should only include the results of the study in substance. It should be rearranged.

Reviewer 3 Report
The paper is devoted to a rather important topic. The authors conducted an experimental study on the study of operating modes with the use of lubrication.
On lines 105–110 you write briefly about your work in the article. Please write in more detail what exactly is new you use, and what innovative technologies were used to build stands for modeling rotor systems.
In Figure 1, there are no captions under the arrows. There is an error in the text instead of links to figures.
If possible, it is better to present a sharper photograph in Figure 3.
Figure 4 is very small, the labels for the axes and the values on the axes of the graphs are not visible. If these graphs are given as an example, then it may be possible to remove them altogether.
Lines 160–162 are redundant.
On lines 178–183 you write about lower and higher oil pressures. Write the numerical values of these pressures in the paper. Also, when you talk about higher or lower pressures in the paper, it's a good idea to indicate the ranges of these pressures at least in part of the cases.
You have done a lot of work and got a lot of experimental results. When writing conclusions, add specific numerical values to them.

Dear,
The authors improved their manuscript according to the suggestions. There are still minor text flaws to be considered. Please check the necessity of lines 172-174 and 345.

Reviewer 3 Report
The authors corrected the article and responded to my comments. Thanks to the authors.
When corrected, you have two identical captions for Figure 1 (Fig. 1 and Fig. 2).
