Reviewer 2 Report

This study used a modified Archard wear model to investigate the wear patterns of different tooth surfaces in a complex tenon connection structure. Some comments are listed as follows:

 

1.     The flowchart in Fig. 1 is not clear. Some parameters are not introduced in the manuscript such as KMESH, time to change the finite element mesh. What is DeltaN<N?

2.     Some many reference errors: Error! Reference source not found.

3.     Why use 20 µm to simulate the fretting motion of disk? More importantly, how to determine the positions of RP1 and RP2? Their positions will have significant effects on the fretting wear.

4.     The load of aerodynamic load on the blade shown in Fig. 21 is too simple. A pressure distribution is more reasonable.

5.     The effect of fretting wear on the contact behavior between the disk and blade is not studied. Please refer to some references such as International Journal of Fatigue 2021;142:105928.

6.     The wear coefficient is not provided.

7.     No validation of the numerical approach
