Research on Mechanism of Fatigue Life Enhancement in Ball Bearings by Residual Compressive Stress

While the beneficial effect of residual compressive stress (RCS) on rolling bearing fatigue life is empirically well-established, the underlying mechanisms, particularly its influence on the subsurface stress field responsible for fatigue initiation, remain inadequately explored....

Physically Constrained Dual-Branch Front-End Optimization for DDH-Oriented Surgical Robot Navigation

Surgical robot navigation in a restricted pelvic workspace requires accurate target localization, directional consistency and robot-feasible execution. This study proposes a physically constrained dual-branch front-end network (PCD-Net) for DDH-oriented navigation using public CT...
