Reviewer 2 Report

This paper analyzes the mechanical properties of the four-star type crank linkage mechanism. The modeling and analysis process are illustrated in details with abundant data support. However, there are still some problems needs to be improved.

(1) Overall, the paper focus the mechanics performance analysis of the mechanism, through modeling, simulation, and experimentation. But it seems to be limited to this. As a research paper, this is not enough. First of all, it is difficult to judge what is the innovation of this paper? Is this four-star type crank linkage mechanism novel? As the author wrote in the abstract, the purpose is to improve the performance of the mechanism. Then improvement methods should be proposed for the performance defects after analyzing the performance.

(2) Is the “specificity analysis” in the title appropriate? Specificity analysis is the concept of statistical analysis of product quality. It would be better to change to “mechanical performance analysis” or some other words.

(3) The introduction part of this paper is not sufficient and not very relevant to the content of this paper.

(4) The length of this paper is too long and the focus is not prominent. It is recommended to delete some contents and clarify the key content. For example, the contents of Fig.4.2 and Fig.4.3 do not make much sense.

The english language of this paper is acceptable.
