Reviewer 2 Report
(
Thanks for your peer-review invitation for the paper titled “Analysis and optimization of a microgripper driven by linear ultrasonic motors”. The end-point positioning accuracy for the microgrippers is critical to the various applications. At this point, this study is significant to positioning accuracy for precision engineering. After careful checking, some concerns about this study are provided in the following comments for further revision.
(1) Both fig 4 and fig 5 are so simple, that they may be combined.
(2) The effects of materials properties and designed structures are important. However, it is inappropriate to discuss them together as influencing factors.
(3) All parameters should be normalized in the section on sensitivity analysis, even if it is necessary to discuss the influence of both materials and structural parameters at the same time.
(4) In section 3 Structure optimization, whether the influence analysis of material parameters is suitable or not. This question should be concerned carefully by the authors.
(5) The logical connection of the work carried out in this paper has not been explained in the article. Especially for the mixed research work of analytical method, finite element method, and experimental method, if there is no strict verification relationship between them, this logical explanation is very necessary.
(6) In addition, there are several hyperlinks in the pdf text, the reason is unknown, please edit the reference. (e.g., “lower power consumption” p1 line37; “excited vibration”, p2, line50; “velocity profiles”, p2, line57)
