Short summary
A thermoelastic hydrodynamic lubrication (TEHL) model with interface micro-texture (IMT) evaluates load-bearing capacity. The model characterises the textured interface with micro-convex peaks (MCPs) by introducing an equivalent scale factor and an optimised distribution density function. A mathematical framework quantifies anti-scuffing load-bearing capacity (ASLBC) under steady-state TEHL, revealing coupled stiffness–damping in a micro-textured meshing interface (MTMI) under dynamic loading.

An electrohydraulic servo four-legged heavy-duty (FLHD) robot has been designed and developed. An integration layout cylinder design scheme for a non-lightweight hydraulic servo four-legged robot with high loads and torque of the hip joint is proposed, and the mathematical element analysis model for a parallel-executed cylinder (PEC) system is derived. A design idea of a force–position hybrid control scheme is determined for the PEC.

Short summary
A comparison between the results obtained by the MsP method and the numerical integration method proves that the former is ideal and credible in most regions. The effects of the time-varying parameters and the nonlinear deenthing caused by the gear teeth clearance on the amplitude–frequency characteristics of TsSCS components are studied. This is a part of research on transmission gears' thermal deformation for application in warship power rear drive systems.

This study performs an analytical study of the modal and natural frequencies and the vibration types of each order of the gearbox housing structure of a planetary gear reducer (PGR). An optimal housing structure for a PGR with lower acoustic vibrations is designed, and a composite housing structure with damping vibration attenuation and acoustic absorption is proposed. The radiation acoustic characteristics without acoustic protection and damping materials are analyzed.

Short summary
This study examines deep-sea gear lubrication challenges under extreme conditions, including high pressure, with a focus on EHL (elasto-hydrodynamic lubrication) theory and interface texturing advances. Critical gaps remain in multi-physics coupling and synergistic texture-coating interactions. The paper proposes a research roadmap integrating multi-scale modelling, surface engineering optimization, experimental validation, and industrial implementation to enable robust deep-sea transmission systems.
