Control of Stick-slip Oscillations in Oil Well Drill Strings Using the Back-stepping Technique
This paper deals with the problem of suppression of stick-slip oscillations in oil well drill-strings. The backstepping technique is used to design two control schemes for the system. The first controller is a typical backstepping controller; the second controller is a sliding back-stepping controller. Moreover, a reduced order observer is proposed to estimate the unmeasurable states of the sys...
متن کاملOptimization of a Roller Levelling Process for Al7001t9 Pipes with Finite Element Analysis and Taguchi Method
This paper is concerned with optimization of process parameters for a roller leveller that is an indispensable equipment to eliminate the undesirable curvature of a thin-walled aluminum pipe. Optimization of process parameters has been carried out for a multistaggered-type 14-roller leveller. A finite element model of a multi-staggered 14-roller leveller was constructed for analysis whose resul...
متن کاملA Continuum Shell-beam Finite Element Modeling of Buried Pipes with 90-degree Elbow Subjected to Earthquake Excitations
In the current work, the seismic analysis of bent region in buried pipes is performed, and effects of soil properties and modeling methods on pipe’s response are investigated. To do this task Beam, Beam-Shell Finite Element modeling and a Continuum shell FE models of a 90 degrees elbow are employed. In the Beam model, the pipe is simulated by beam elements while combined shell-beam elements a...
متن کاملfinite element modeling of deformation field induced by dip and strike slip fault coseismic activity
many earthquakes occur in iran every year and some of these earthquakes cause loss of life and property. consequently earthquake is one of challenging topics not only in iran but also in other active tectonic regions in the world. investigating the mechanism of earthquake as a natural disaster is the first and important step. to study earthquakes, different information such as geometry and beha...
متن کاملFinite Element Methods for Geometric Modeling and Processing Using General Fourth Order Geometric Flows
A variational formulation of a general form fourth order geometric partial differential equation is derived, and based on which a mixed finite element method is developed. Several surface modeling problems, including surface blending, hole filling and surface mesh refinement with the G continuity, are taken into account. The used geometric partial differential equation is universal, containing ...
