This study investigates the stability and phase difference of a shaft Screens mounted a dry friction damper with effects of viscous internal damping and gyroscopic moment.The equations of the system with the vibration reduction effect of the dry friction damper on the shaft are derived in the form of the rectangular coordinate and polar coordinate
There have been numerous studies on dinosaur biogeographic distribution Hoodie patterns.However, these distribution data have not yet been applied to ecological questions.Ecological studies of dinosaurs have tended to focus on reconstructing individual taxa, usually through comparisons to modern analogs.Fewer studies have sought to determine if the
