Abstract: Using a ring-on-block wear test machine, friction and wear tests were carried out on a PSZ (partially stabilized zirconia) ceramic-steel pair under the lubrication conditions of paraffin oil and ...

Abstract: In order to elucidate the tribological behavior of the Si3 N4 ceramic used in automobile engine, a series of tests was carried out to measure the friction coefficient and wear resistance of ...

Abstract: This article develops a novel event-triggered sliding mode control (ETSMC) approach with variable threshold to deal with trajectory tracking matters of autonomous underwater vehicles (AUVs) accompanied by actuator saturation ...

Abstract: The operation performance of expansion joints is crucial to the driving safety of high-speed trains and the structural integrity of long-span bridges. However, the fact that displacement in expansion joints is influenced ...

Abstract: The surface roughnesses of two surfaces in a wear contact can change throughout the course of the wear process. This may or may not change the lubrication mechanism of the system depending ...

Abstract: Due to the designing characteristics of long span and low stiffness, the high-order vortex-induced vibration (VIV) of suspension bridges may occur under a special wind environment. The prototype monitoring data make it ...
