The Homotopy Perturbation Method For Free Vibration Analysis Of Beam On Elastic Foundation, Baki Ozturk, Safa Bozkurt Coskun Dec 2010

The Homotopy Perturbation Method For Free Vibration Analysis Of Beam On Elastic Foundation, Baki Ozturk, Safa Bozkurt Coskun

Safa Bozkurt Coskun

In this study, the homotopy perturbation method (HPM) is applied to free vibration analysis of beam on elastic foundation. This numerical method is applied on three different axially loaded cases, namely: 1) one end fixed, the other end simply supported; 2) both ends fixed and 3) both ends simply supported cases. Analytical solutions and frequency factors are evaluated for different ratios of axial load N acting on the beam to Euler buckling load, Nr. The application of HPM for the particular problem in this study gives results which are in excellent agreement with both analytical solutions and the variational iteration …


Us Patent 7,501,922: Permanent Magnetic Male And Female Levitation Supports, Sanza Kazadi Mar 2009

Us Patent 7,501,922: Permanent Magnetic Male And Female Levitation Supports, Sanza Kazadi

Sanza Kazadi

A  permanent   magnetic   male   and   female   levitation  support  has   a  first   part  with   a  cavity   and   a  plurality   of  retainment   mechanisms incorporated therein, and a plurality of first permanent magnets evenly distributed around the perimeter of the cavity and held in place by the retainment mechanisms, wherein the first permanent magnets produce a first rotationally invariant magnetic field around a first axis.  A second part is rigidly connected to a base and produces a second rotationally invariant magnetic field around a second axis. When the  
first axis is aligned with the second axis, the first magnetic field and the …
