Opis

The goal of this book is to present general methodologies for dynamic analysis of mechanical systems with imperfect, that is, considering joint clearances and their tribological characteristics and surface compliance properties. Two and three- dimensional comprehensive methodologies for imperfect kinematic joints with and without lubrication are proposed. In the sequel of this process, different contact-impact force models are revisited in face of their suitability to represent collision between the bodies connected by imperfect joints. The incorporation of friction forces, based on the Coulomb friction law, is also discussed. Moreover, a general methodology, which accounts for squeeze-film and wedge-film actions, including the cavitation effect, for modeling dynamically loaded journal bearings is also presented. The equations that govern the dynamical behavior of the general mechanical systems incorporate the contact-impact forces due to the collision between the bodies that constitute the imperfect joints, as well as the hydrodynamic forces owing to the lubrication effect.
