configuration tunedmass damper(ACTMD). By continuously adjusting its operating state, it can cover most of the operating frequency range. As shown inFig. 7(b)), the ACTMD structure consists of a base, a pivot, a spring, a turntable, and a moving mass block. The frequency of the ACTMD...
The lumped parameter modeling techniques involve representing the drillstring as a mass-spring-damper system. In a lumped system the dependent variables of interest are a function of time only, making it possible to describe the system mathematically using ordinary differential equations thus making the...
