Galaitsis, George Stergios2014-03-142014-03-141993-05-05etd-05042010-020305http://hdl.handle.net/10919/42484A theoretical technique to extract drilling-angular velocities from a nodal-spatial array of in-plane translational velocities is developed. The technique utilizes numerical methods for simulation of solutions. A finite element method using I-DEAS 4.1 is used for calculation of in-plane translational velocities and a MATLAB code is written for extraction of the drilling-angular velocities. The case of data with noise content is also considered. All numerical results are compared to a closed-form theoretical solution which is used as a reference for accuracy. Recommendations are made for future testing and experimental applications of this technique.xii, 101 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1993.G353Rotational motion -- Mathematical modelsThesishttp://scholar.lib.vt.edu/theses/available/etd-05042010-020305/
