The paper presents an application of reassigned wavelet scalogram for rotor system fault diagnosis. It is a topic of interest to the researchers in the related areas but the paper needs very significant improvement before acceptance for publication. My detailed comments are as follows:

1. The wavelet method (reassigned wavelet scalogram) used in the paper works very well for the underlying fault diagnosis problem. On the other hand, this wavelet method is a

well-established method, and the present research is a direct application of this method without new contribution in methodological research.

2. For the above reason, the presentation should be focused on the results. Unfortunately, the presentation is far from acceptable for publication. The material was not properly organized and it is strongly suggested that the authors check carefully the English writing and use standard terminologies in the technical area.

3. The title of the paper should be more specific since numerous studies have been done on the fault diagnosis of rotor systems using wavelets and time-frequency methods. Also, remove the word "research".

4. On Section 1:

· This section listed many references that are mainly related to rotor dynamics and are not directly related to rotor system diagnosis. If the authors would like to keep these references, some discussions on the relevance of these refs to the present research are needed.

· Review on the directly relevant refs will be more helpful for the reader. Also, time-frequency and wavelets are mainly for non-stationary and transient analysis. The author may discuss in more detail what types of transients and non-stationary components would appear in rotor system vibration.

· A few sentences on the organization of the paper will be helpful.

5. On Section 2:

· Since the major method used in the application is reassigned wavelet scalogram, it is not needed to give the details of three other methods (only give a few words and give the refs). Instead, the authors may discuss more on the relationship between traditional wavelet scalogram and the reassigned wavelet scalogram, and explain why the latter is better than the former.

· Eq (2): the right-hand-side is wrong and "2" is missed.

· The description after Eq (2) is not clear. See Cohen's book for details about the cross-terms.

6. On Sections 3 and 4:

The description needs to be improved. The material in Section 3 should be organized in several paragraphs.

7. On Section 5:

· The authors did a good experiment and some of the phenomena presented in the

time-frequency planes are also very interesting. However, the observations should be described concisely, and the authors should focus more on: 1) whether these phenomena are general characteristics, and 2) if possible, explain the reason of the phenomena and the advantages of reassigned wavelet scalogram over other time-frequency methods.

· In fact, it is possible to interpret most of the phenomena in the time-frequency planes using
