Abstract: Preload, which is widely applied in linear motion ball guide (LMBG) to eliminate clearance and increase stiffness, gradually decreases owing to wear, resulting in the degradation of the load-bearing capability and dynamic ...

Abstract: Owing to the measurement difficulty and the required time needed to analyze wear processes of ball screws, very few studies have been reported. Here, on the basis of a test bench and a Taylor Hobson surface profilometer, ...

Abstract: The flow compression process design is critical for enhancing the efficiency and overall performance of hypersonic airbreathing propulsion. Many studies have sought to solve the challenging problems that inlet design ...
