We consider a boundary-value problem for the beam equation, in which the boundary conditions metal-anal mean that the beam is embedded at one end and fastened with a sliding clamp at the other end.Some priori estimates to the positive solutions for the boundary-value problem are obtained.Sufficient conditions for the existence and nonexistence of p
Ball screw preload is an important factor in maintaining repeatably, rigidity, and in reducing or eliminating backlash in feed drive systems.Ball screw feeds drives are used in computer numerical control (CNC) machine tools to manufacture high-quality, precision parts.Many fault detection and condition monitoring (CM) methods have been proposed for
