Abstract: The functional parts of a machine tool determine its reliability level to a great extent. The failure prediction of the functional part is helpful to prepare the maintenance scheme in time, in order to ensure a stable ...

Abstract: Recently, some researchers have studied the frequency characteristics of a quartz crystal resonator (QCR) covered with micropillars to measure the physical and geometric parameters of the micropillars. A recent study showed ...

Abstract: Acting as an important internal excitation, sliding friction can cause the vibration and noise of the planetary gear set. In this paper, a dynamic model is developed to study the influence of sliding friction on the dynamic ...

Abstract: Based on the assumption that the hydrostatic pressure is maximum at half the total groundwater level, which improved the groundwater pressure distribution in the slope body, the safety factor expression for anti-slide ...
