Special Issue Information

Dear Colleagues,

The safe and reliable operation of mechanical systems requires sufficient structural strength and accurate interface behaviour due to concerns over the structural failure of mechanical parts, surface and interface science, and tribology. Accurate control of extreme manufacturing and complex equipment under various external field conditions, multi-form energy transmission, multi-level information operation, and multi-interface coupling act to guarantee the accurate and stable operation of complex systems. In extreme or special environments, the failure of precision machinery may not be a result of geometric or traditional mechanical problems, but rather stem from changes in physicochemical processes at the interface of mechanically active joints. However, there is no correlation between material surface research and mechanical motion design, and high-end equipment remains in the stage of multi-scale mechanical design, which is separated from micro interface science and macro mechanical science. Therefore, breaking through the barriers between interface science and mechanics, and introducing modern interface physics results into mechanical design, has become an urgent need for the development of high-end equipment and intelligent manufacturing. Coating is one of the important means of modifying the physical and chemical environment of a mechanical surface boundary and is a key field of material surface research. Therefore, it is of great significance to carry out research on surface interfaces and coatings in mechanical system engineering and establish the facts of their mechanical operation, with perspectives ranging from the micro scale of the surface interface to the macro scale.

This Special Issue focuses on coatings and surface interfaces in cross-scale mechanical system engineering. Topics of interest in this special issue include (but are not limited to):

  • Surface interface science and coating technology in mechanical systems;
  • Surface interface behavior and coating technology under extreme environment service, such as space environments, radiation, etc.;
  • Precise control of surface interface in the field of machine forming manufacturing;
  • A cross-scale combination of existing inspection technologies for efficient and accurate coating defect detection;
  • Modelling and predictive research to establish the relationship between detection data and coating performance to effectively achieve coating health monitoring;
  • Simulation and intelligent design of surface interface and coating.

Grinding technology exerts an enormous effect on the surface quality of double helical gears, which are subject to stringent requirements in the aviation industry. This study presents a novel gear-gap-space-borrowing grinding method that diverges from existing techniques. Unlike conventional approaches, this method mitigates the design–manufacturing conflict by exploiting the opposing gear gap space. By borrowing space, the grinding wheel’s size can be enlarged to enhance machinability, diminish the width of the undercut, and align with the lightweight design imperative of double helical gears. The relationship between the grinding wheel diameter and the design parameters of double helical gears is analytically established, leading to the formulation of design rules. These rules facilitate the rapid selection of appropriate grinding wheel sizes for the space-borrowing method. Additionally, through geometric modeling and experimental validation, the optimal gear undercut width and the maximum wheel diameter are determined. The validity and accuracy of the proposed method are verified by simulations and experimental investigations. The study quantitatively evaluates the benefits of this method, including the expansion of the grinding wheel size, the reduction in double helical gear weight, and enhancements in processing efficiency and quality, providing a comprehensive comparison and discussion of these improvements.
