Grease is extensively used in rolling bearings due to its inherent sealing properties. However, mechanical degradation typically occurs, resulting in a significantly shorter lifespan for the grease compared to the bearing. Investigating aging mechanisms
Energy absorbing efficiency is a key determinant of a structure’s ability to provide mechanical protection and is defined by the amount of energy that can be absorbed prior to stresses increasing to a level that damages the system to be protected. Here,
Engineering simplification algorithm Assuming that the contact surface of the spherical hinge is a flat disk, the radius is R, and the upper transfer load is F, the contact pressure of the spherical hinge interface can be calculated by formula (1), which is also a calculation method generally...
Along the axial direction of the face milling cutter, the flank edge participating in cutting is discretized into the microelement cutting force model with axial heights of dz, as shown in Figure3(b). Each part can be considered as an oblique cutting state. Throughout the cutting process, the...

Initial residual stress is the main reason causing machining deformation of the workpiece, which has been deemed as one of the most important aspects of machining quality issues. The inference of the distribution of initial residual stress inside the bla
