Abstract: Abstract. This study investigates the effects of zinc dialkyldithiophosphate (ZDDP), molybdenum dialkyldithiophosphate (MoDDP), and potassium borate (PB) on the replenishment performances and vibration resistance of polyurea ...

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: AbstractHeavy equipment operators on construction sites are required to remain seated in the cockpit for prolonged periods while performing work with high psychological intensity. Cognitive abilities are essential for these ...

Abstract: AbstractSlip, trip, and fall (STF) events remain the primary cause of reported injuries in the construction industry, highlighting the crucial necessity of efficient monitoring systems. Conventional monitoring approaches, ...

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 ...
