Optimization of shotcrete manipulator motion trajectory based on AIWCPSO algorithm [PDF]

Gong-kuang zidonghua
To address issues in traditional shotcrete manipulator trajectory planning algorithms, such as abrupt transitions between multiple path segments and low shotcrete efficiency and uniformity caused by frequent starts and stops, an optimized motion ...

Preventive measures of fretting wear in contact surfaces of inner ring and backing ring of railway axle journal bearings (Combined effect of grooving and segment‐structured DLC coating towards backing rings)

Nihon Kikai Gakkai ronbunshu, 2019
Fretting wear is surface damage caused by repeated slight relative slips between two contact surfaces. In railway applications, fretting wear may occur between the inner ring and the backing ring of an axle journal tapered roller bearing.
