Response to Reviewer Comments

1. Section numbering should be revised.

Response 1:

We are sorry that we have made an error in the chapter number. Now we have revised the chapter number.

 

2. In the conclusion section, there is no talk about the limitations and the future of the work of the research, and this section needs to be rewritten.

Response 2:

Since the skyhook control method is more suitable for MRF damper output control force, this paper establishes a semi-active control method based on skyhook control, but the control effect on the suspension can be further improved, which requires further research on the control algorithm. Now we have explained this in the conclusion section. And we marked all the changes in revised manuscript in red.　

We tried our best to improve the manuscript and made some changes in the manuscript. Thanks again for your comments on our article!

Sincerely yours

Reviewer 2 Report

The article uses semi-active suspension module in the seat suspension system. It can be seen that there is a lot of work in this article, but English still needs to be improved.

 

Minor comments are as follows:

1.     It is better to proof reading English. Some sentences are too “Chinglish”, like “According to the inverse kinematics equation, the relative motion velocity of each leg of the Stewart mechanism can be obtained by the velocity of the center position of the upper and lower platform. On the other hand, the forward and inverse dynamic models of MRF damper are established, which lays the foundation for semi-active control of the seat suspension.”,” The Instron E10000 electronic dynamic testing machine to test the MRF damper is shown in Figure 2”,” Universal sections connect the lower platform and the lower rods of each leg, and a cylindrical section connects each leg's lower rod and upper rod. Universal sections connect the upper rods of each leg and the upper platform.”

 

2.     In page 3, “MRF dampers using an intelligent material”, it is better to use “smart” material not intelligent material.

 

3.     There are two serial numbers behind some formulas (page5, page9 etc.). Please see if it is a problem of typesetting.

 

4.     It is better to draw X, Y, Z coordinate axes in Figure 9.

 

5.     Do the two excitations mentioned in Figure 10 have directions? Like along x axis?

 

6.     In page 15, “As explained above, when the excitation frequency is 1.414 times higher than natural frequency,”, How to get the data of 1.414? Better write clearly.

 

7.     The latest reference is published in 2018, it is better to add some research in recent two or three years.

Reviewer 3 Report

In the Reviewer opinion, the present technical note could be of interest to the readers of Applied Sciences. Indeed, the topic is relevant and scientifically founded. However, some critical aspects, detailed in what follows, should be properly reconsidered by the authors before the paper can be accepted for publication.
