Abstract: Abstract. A novel dynamic model of ball bearings including all of bearing parts with full degrees-of-freedom is developed, in which the relative positions of bearing parts are used to calculate iteratively the real-time ...

Abstract: It is of great significance to study the dynamic movement of temperature and pressure during depressurization mining process of hydrate reservoir. This paper first obtains the formula for calculating the temperature and ...

Abstract: An improved nonlinear dynamic model of high-speed ball bearings with elastohydrodynamic lubrication is adopted to predict the movements of balls and power loss of ball bearings for defining the boundary conditions of a ...
