Preliminary Selection of Road Test Sections for High-Mobility Wheeled Vehicle Testing under Proving Ground Conditions

Round 1

Reviewer 1 Report

Dear author, 

I am glad to review your submitted paper that foucs on high mobility wheeled vehicle test. In genral, this paper gives clear methods on how to improve vehicle's performances during the test, such as speed. But the delivered results are not enough and not so clear to support your applied methods. From my perspective, some corrections (see below) should be done to apporach final submission:

1. This is accademic paper, which should aovid ethical concerns: war or invasion, which is not a friendly word in the paper, please aovid it.
2. A lilttle bit of concern on militaristic information shown in paper (such as Figure 5), which should get promission or approval from relative institute in your country before you submition. 
3. Tests on different roads (not clear information on those road), please define the road in your results: specifications of road 1-16 with a table
4. Additional information shold be given: test photos on different roads
5. High-quaility figures are needed, such as Figure 6 and Figure 8 (it would be better to focus on samll range of loading and give another figure to show data in large range
6. There may have other English language and style errors, please have a double check before the submission.

Best wishes,

Chao

Dear Reviewer

I would like to kindly thank you for all the valuable comments to the submitted paper. In the revised version of the paper, I have taken into account the comments and added the necessary information and clarifications:

• The topic of the article is not limited to military vehicles only, but to the group of high mobility wheeled vehicles. I have changed the context in the introduction by pointing to other, civilian application areas of the mentioned test method
• The information presented in this paper is unclassified and does not require permission to be published from the vehicle manufacturer or any other party
• The road test sections used in the study were off-road class roads, which do not have a stable surface and cannot be parameterized in a permanent way. Therefore, it is not possible to present detailed parameters describing those roads. The method presented in the paper is concerned with the quick classification of selected test road sections and the assessment of their suitability for testing vehicle. In the revised paper, I have added additional data in Table 3 and pictures with examples of the road sections used in the study (Fig. 5)
• The figure with unclear data has been changed. In the current version the data are better presented
• I have done my best to eliminate some language errors. I hope that the submitted version can be accepted

 

I hope that the corrections made to the paper and the explanations provided will be accepted by the Reviewer

Reviewer 2 Report

This study presents a method for evaluating the suitability of selected test road sections for durability tests of a special military high mobility wheeled vehicle. Unfortunately, this manuscript could not be published in the present form.  The major concerns are
1) the presented method is specifically targeted at military vehicles, which may be not suitable to the social vehicles. Regarding this, the method and the findings have no universal values for reference by others.

2) lots of information about the vehicle, roads, test results are not given, which are essential parameters for verification and convinced by the reviewers.

3) the Introduction has refered many reports, some may be also classified, this seems unfriendly to the readers.

4) The outline of this paper is suggested to add in the last paragraph of Introduction, to make this article more readable.

5)  There is a lack of implementation steps of the presented method.

6) Figure 5 is duplicated.

7) The information about the 14 test roads should be given to make the results convinced.

8) The results in Figs. 6,7 and 9 have no strong support to the effectiveness of the presented method, please argue.

Dear Reviewer

I would like to kindly thank you for all the valuable comments to the submitted paper. In the revised version of the paper, I have taken into account the comments and added the necessary information and clarifications:

• The topic of the article is not limited to military vehicles only, but to the group of high mobility wheeled vehicles. I have changed the context in the introduction by pointing to other, civilian application areas of the mentioned test method
• Additional technical data on the vehicle are shown in Table 2. The road test sections used in the study were off-road class roads, which do not have a stable surface and cannot be parameterized in a permanent way. Therefore, it is not possible to present detailed parameters describing those roads. The method presented in the paper is concerned with the quick classification of selected test road sections and the assessment of their suitability for testing vehicle. In the revised paper, I have added additional data in Table 3 and pictures with examples of the road sections used in the study (Fig. 5)
• The list of references attached to the paper is unclassified. Only item [1] is confidential, but it is not necessary to view its contents in order to understand the meaning of the paper
• In the Introduction paragraph I have added supporting information to the body of the article to make the paper more readable
• In the Conclusions, the main steps of the implementation of the proposed method are presented
• Numbering of figures has been corrected
• As mentioned before, the road test sections were off-road class - their surfaces were not solid and they were not parameterized. Additional data for the test sections, including section 14, have been added to Table 3.
• Figures 6 and 7 (in the revised version 7 and 8) refer to the derived speed distributions for a preliminary verification that the required ranges are appropriately represented during the tests. Based on the data presented, it can be indicated that the higher speed contributions generally have a low representation in the tests. Figure 9 (revised version 10) indicates whether the excitations recorded in the left and right tracks are symmetric. The data presented demonstrate that the loads generated under the wheels on the right side are between 1.5 (road 5) and 8.3 (road 14) times greater than under the wheels on the left side. This results in excessive loading of the components on the right side of the vehicle and underestimation of the loads on the left side. A solution in this case could be to change the direction of drive on each road test section and recheck whether load balance has been achieved.

 

I hope that the corrections made to the paper and the explanations provided will be accepted by the Reviewer
