Influence Analysis of Lubricant Recesses on the Working Capacity of the Bridge Span Spherical Bearing
Round 1
Reviewer 1 Report
The analysis of the influence of sliding surface lubrication recesses made of polymeric materials on bridge structure has been paid much attention in transport industry. In this study, numerical algorithms for the automated creation of mathematical models of bridge bearings and investigation of their contact deformation behaviour with automated processing of the results were constructed. The influence of the geometry and location of the recesses on the deformation behaviour of the bridge bearing structure was evaluated. The paper can be considered for acceptance if the following minor questions could be addressed seriously.
(1) In Abstract, a brief description of the background and difficulties is recommended so as to facilitate understanding of the need for the study when reading.
(2) The parameter selection is crucial for model building and mathematical simulation, especially in this study. Therefore, in Section 2.1, the selection of specific values of parameters is listed. Meanwhile, the presentation of the reasons for the selection is also necessary.
(3) At line 149, a flowchart of computational experiments is exhibited. It is suggested that the text in the flowchart could be more concise and that the different processes could be represented in blocks.
(4) At lines 151 to 154, the input parameters are listed centrally. All input parameters should be listed directly, not just partially important ones as in Abstract with 'etc'.
(5) In Results, the phenomena due to the variation of geometric parameters are mentioned. In Discussion, limitations and materials are mentioned. A systematic overview of the intrinsic or mechanistic relationships between parameters and phenomena in Discussion is expected.
(6) Too much text and content in Conclusions.
At line 368, Nomenclature is displayed, however, it does not seem to include all the abbreviations proposed in this article.

on paper “ Influence analysis of lubricant recesses on the working capacity of the bridge span spherical bearing “ (lubricants-2003763) by authors Yuriy O. Nosov , Anna A. Kamenskikh submitted to Lubricants
This is interesting paper. It reports the contact deformation of the elements of the spherical bearing through an antifriction polymer layer with different geometrical configurations of recesses for the lubricant: annular grooves and spherical holes. The influence of the arrangement of filling sliding antifriction layer by recesses for the lubricant in the form of spherical holes on the contact deformation behaviour of bridge bearings has been considered. The reduction of the lubricant volume in the sliding antifriction layer with the geometry of recesses in the form of spherical holes ranging from 26 to 48,4 % depending on the filling scheme has been found. I have no doubts about the reliability of the information presented and its analysis. However, I have some comments and additions. I would like to note a few points to improve the paper before it can be published:
1. The authors should mention in 1. Introduction some information about composite materials are perspective for practical applications:
