Moreover, the influence of crack propagation conditions on the meshing stiffness of the planetary...

... rod structure. Conventional lubrication theory underestimates the gap width because it assumes that the structure is a rigid body, so it is necessary to perform analyses based on elastohydrodynamic lubrication (EHL) theory, which treats the structure as an elastic body [ 11 – 16 ]. In general EHL...
