Research on the Influence of the Assembly Parameters of the Junction Surface of Ultrasonic Acoustic Components on the Acoustic Performance Parameters

Round 1

Reviewer 1 Report

1.        An extra space at line 46 causes the statement to break. Please correct it.

2.        In table 1, the word (specification) is split into two lines, please adjust the table.

3.        When vaseline oil lubrication is used, the effect of the medium variation between the junction surfaces on the acoustic transmission should be discussed.

4.        When discussing yield strength and tensile strength, please state the material of the part.

5.        When the instrument is used, please state the place and manufacturer of the instrument.

6.        Please correct the punctuation at line 318.

7.        Temperature has a certain impact on the performance and life of ultrasonic acoustic components. When discussing the temperature variation, attach the temperature distribution image at the junction surface and declare the temperature measuring equipment used.

8.        In Fig. 6 and 8, the coordinate division is too rough to read out in detail the image variation of the Pre-tightening torque between 0-20 N·M.

1. The problem has been corrected.
2. Table 1 has been modified as required.
   
   
3. The influence of lubricant change on the acoustic transmission performance of the interface is a complex scientific problem. At present, this paper only studies the influence of the junction surface with or without lubricant on the static performance parameters of the acoustic vibration component from a qualitative point of view, which is described in Section 4.1.2. The reviewer put forward a good research direction on the influence of the change of Vaseline lubricating oil on the interface acoustic transmission performance, which is also a difficult problem that the author wants to explore in the later research.

4. This problem has been modified by adding part material at lines 174 and 177. 

5.  The place and manufacturer of the instrument are indicated in line 243. 

6. The punctuation problem has been corrected.

7. The temperature measurement equipment has been supplemented, as shown in Figure 10.  Because this paper studies the temperature of the transducer, the temperature of the junction surface is not studied. So the temperature distribution of the transducer is supplemented, as shown in Figure 11. 

8. The coordinate scale of Figure 6 and Figure 8 has been refined.

Reviewer 2 Report

The article looks quite interesting and scientifically substantiated. However, there are a few small remarks.
1. Page 3, Line 115. The terms Joint surface in Figure 1 are incompatible with Junction surface in the text of the article.
2. Page 4, Line 134 and forward. The term Newton-meter must be abbreviated to the symbol N*m, the letter m is lowercase.
3. Page 4, Line 142 and forward. In the formulas, not all symbols are explained. Formulas 2.2 and 2.3 should be supported by references to the literature.
4. Page 4, Line 464, Figure 11 and Page 16, Line 514, Figure 14. The power symbol W must be a capital letter. From the text of the article it is not entirely clear what power is meant: the electric power supplied to the piezoelectric transducer or the acoustic power on the acoustic horn. What is the measurement purpose of the laser displacement sensor?

Author Response

1. The terms joint surface in figure 1 has been corrected.
   
   
2. The abbreviation of the term Newton-meter has been corrected to N * m.

3. In lines 140 and 145-147, the explanation of the missing symbols in the formula is supplemented. In line 604, we supplemented the reference [11] to support formulas 2.2 and 2.3.

4. In line 478, Figure 13 and 529, Figure 16，the power symbol W has been changed to capital letters. In lines 477 and 528, the measured power of acoustic vibration components (Power measured at transducer end) is added. As shown in Fig. 10, the laser displacement sensor can measure the end amplitude of the ultrasonic horn and the longitudinal vibration amplitude of the tool tip.  This paper needs to study the influence of the assembly parameters of the ultrasonic horn junction surface and the assembly parameters of the tool head junction surface on the dynamic performance under the fixed amplitude, which is described in Sections 5.1 ，Line 426 and Section 5.2, Line 494.
