The 3-D traction field in the pressure screw-pair of a 3 500 heavy and medium plate mill press down system is successfully calculated by applying the 3-D fricti
Based on a lot of numerical solutions to the problems of the thermal non-Newtonian elastohydrodynamic lubrication and some fatigue tests with rollers, the lubri
Several 2-D displacement sensing methods are reviewed. As to the cross diffraction grating,there is no absolute zero-reference. In regards to the optical fiber
