Bearingless permanent magnet synchronous motor (BPMSM) has the characteristic of both conventional permanent magnet synchronous motor and traditional magnetic bearings. In this paper, the design and analysis of BPMSM by using Matlab/Simulink and ANSYS Maxwell are presented. The principle of electromagnetic force is utilized to ensure a stable levitation operation of BPMSM. The BPMSM mathematica...

The modern development in mathematics bridges this gap (see Fig. 1). It allows us to start from a high dimensional system obtained by finite elements and then automatically generate a low dimensional approximation. The dimension of a reduced model is controlled by the approximation error specified by the user. In this article the software MOR for ANSYS [1] is presented. MOR for ANSYS applies ne...

Determination of the optimum loading path (internal pressure- axial feeding) to restrict the Bursting, buckling and wrinkling through tube hydroforming process is necessary to produce an acceptable tube. In this paper, the wrinkling and fracture criteria are implemented to an finite element code devoted to the simulation of tube hydroforming processes. Using the ANSYS parametric design language...

To the 36 meters crane girder with trapezoidal variable cross-section in a steel plant, finite element model is established reasonably according its actual size. The calculation of crane girder structure was introduced by using the finite element analysis software ANSYS. The local stress state of the cross-section is investigated and the stress concentration position of variable cross-section i...

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...

The work presents the Finite element study of the effect of elliptical chords on the static and dynamic strength of tubular T-joints using ANSYS. Two different geometry configurations of the T-joints have been used, namely Type-1 and Type-2. An elastic analysis has been considered. The Static loading conditions used are: axial load, compressive load, In-plane bending (IPB) and Out-plane bending...

Complex mechatronic systems like machine tools are characterised by a close interdependence of physical domains (electrical and mechanical hardware) and logical domains (information processing devices). A novel simulation method, implemented in ANSYS control toolbox links those domains in the finite element software. Preliminary trials qualified this approach to be suitable in the design proces...
