Rails play a vital role in the bearing and guidance of high-speed trains, and the normal condition of rail components is the guarantee of the operation and maintenance safety.Fasteners are critical components for fixing the rails, so it is particularly important to detect whether they are in a normal state or not.The current rail-fastener detection

Simulation Analysis of Skew Collision of Needle Roller Bearing Used in Precision Cycloid Reducer
In order to improve the service life of the needle roller bearing used in a precision cycloid reducer, and to reveal the skew and collision phenomenon of the needle roller bearing, based on the force analysis of the transmission mechanism of the cycloid reducer and considering the friction between the cycloid wheel, needle roller, cage, and crank s
