Reviewer 2 Report
Comments and Suggestions for AuthorsDear Authors,
I have reviewed your paper titled "Design and experiment of adaptive profiling header based on MBD-DEM coupling" and would like to provide you with feedback and comments. Overall, the study presents a design for an adaptive profiling header that aims to maintain consistent stubble height during the mechanized harvesting of the first season of ratooning rice.
The paper describes the design and experimentation of an adaptive profiling header for rice harvesting. The profiling mechanism is capable of adjusting the height and level of the header, thus ensuring a consistent stubble height during the ratooning season. The study includes theoretical analysis, simulation experiments, and bench tests to optimize and validate the profiling mechanism. The results demonstrate that the profiling mechanism achieves high accuracy in ground profiling, and the structural design is reasonable. The paper also discusses the working principle of the adaptive profiling header and the key component design of the profiling wheel.
Feedback and Comments:
The introduction provides a good background on ratooning rice and the importance of maintaining specific stubble height. However, it would be helpful to include more information on the existing methods or technologies used for stubble height control in rice harvesting and highlight the limitations or challenges associated with them, research gaps and novelty
The description of the adaptive profiling header and its components is clear and well-illustrated. The figures provided in the paper effectively support the understanding of the design.
The experimental approach using MBD-DEM coupling and the mathematical regression model are appropriate for optimizing and evaluating the profiling mechanism. However, it would be beneficial to provide more details on the simulation setup and methodology for better reproducibility.
The results presented in the paper demonstrate the effectiveness of the profiling mechanism in achieving accurate ground profiling. However, it would be valuable to include more comprehensive quantitative results, such as statistical analysis of the data and comparison with existing methods or technologies.
The discussion on the fuzzy PID control algorithm and the utilization of a three-position, four-way proportional valve for adaptive adjustment of the header is interesting. It would be helpful to provide more insights into the control strategy and its advantages over traditional control methods.
The conclusion provides a concise summary of the study's findings. However, it would be beneficial to include a discussion on the potential limitations or future directions of the research, along with suggestions for further improvement or optimization of the adaptive profiling header.
overall, the paper presents a valuable contribution to the field of agricultural machinery and the design of adaptive profiling headers. The experimental results and analysis support the effectiveness of the proposed mechanism. However, I recommend addressing the points mentioned above to enhance the clarity, comprehensiveness, and impact of the paper.

Round 2
Reviewer 1 Report
Comments and Suggestions for Authors1. About Reply 17：Through the author's description, it is intended to reflect the frictional force between the soil and the profiling wheel through the support force, and it is believed that the smaller the value, the easier it is to drive the wheel. At present, the expression in the article is still not very clear, and the author needs to consider the language expression. In addition, based on the current author's approach, should the slip of the profiling wheel be considered in future research? Here, only the reviewer's suggestion is expressed.
2. About Reply 18：This response should be added to the manuscript briefly for readers to understand.
3. About Reply 20：Because the value of Y1 does not have a significant impact on the performance of the mechanism, in the analysis section, it is only necessary to prove that the wheel can operate normally. It is more meaningful to focus the analysis on the other two indicators.
Comments on the Quality of English LanguageThe presentation should be further improved by native speakers, especially for those grammatical errors, and bad structure sentences.
