Abstract: A mathematical model of time-varying thermal elastohydrodynamic lubrication (EHL) is developed using a sleeve chain as the object of study. The effects of thermal effect, load, speed, rest time, and equivalent radius of ...

Abstract: To improve mechanical efficiency, the tribological performance of short-period intermittent motion needs to be investigated. Based on the theory of thermal elastohydrodynamic lubrication (EHL) and considering the influences ...

Abstract: Intermittent motion is a complex process that involves constant speed, deceleration, static stages, and acceleration. Theoretical analysis suggests that shortening the period of intermittent motion can increase the film ...

Abstract: The nondestructive characterization and monitoring of defects in composite structures by ultrasonic guided waves are hindered by the complexity of the interaction. Efficient computational modeling of propagating ultrasonic ...
