Aeroelasticity and Fluid-Structure-Interaction Wading Simulation for Off-Road Vehicles Vehicle wading refers to situations where vehicles traverse through Wing and Spoiler Design water at different speed. One of the major challenge is computing The deformation and dynamic fl utter of aircraft wings or racecar the inertial fi eld of the vehicle while wading. In cooperation with spoilers can be analyzed using combinations of suitable structural Jaguar-Landrover, Fraunhofer has developed a new method of mechanics and CFD codes. Customers from aircraft industry and co-simulation between CFD (STAR-CCM+) and MBS (SIMPACK). leading Formula1 teams have integrated coupled Fluent-Nastran or Abaqus-OpenFOAM solutions in their daily development processes. Thermal and Vibration Loads in Turbomachinery Hydraulic Pump Layout In cooperation with Gdansk University, Bandak Engineering Thermal Loads on Ceramic Impeller developed a new type of axial pumps with cam-driven In order to increase the effi ciency of micro gas turbines by higher commutation units (PWK pumps). An Abaqus-Fluent combination gas temperatures, new material concepts for the high temperature was used to determine the optimal layout for the different loaded parts are required. Fraunhofer has developed a new chambers and to minimize noise and vibration of these pumps. impeller concept (using a thermally coupled FINE / Turbo – Abaqus solution) and applied it for rotation speeds up to 120,000 / min.

  • Comparison of Main Magnetic Force Computation Methods for Noise and Vibration Assessment in Electrical Machines
    JOURNAL OF LATEX CLASS FILES, VOL. 14, NO. 8, SEPTEMBER 2017 1 Comparison of main magnetic force computation methods for noise and vibration assessment in electrical machines Raphael¨ PILE13, Emile DEVILLERS23, Jean LE BESNERAIS3 1 Universite´ de Toulouse, UPS, INSA, INP, ISAE, UT1, UTM, LAAS, ITAV, F-31077 Toulouse Cedex 4, France 2 L2EP, Ecole Centrale de Lille, Villeneuve d’Ascq 59651, France 3 EOMYS ENGINEERING, Lille-Hellemmes 59260, France (www.eomys.com) In the vibro-acoustic analysis of electrical machines, the Maxwell Tensor in the air-gap is widely used to compute the magnetic forces applying on the stator. In this paper, the Maxwell magnetic forces experienced by each tooth are compared with different calculation methods such as the Virtual Work Principle based nodal forces (VWP) or the Maxwell Tensor magnetic pressure (MT) following the stator surface. Moreover, the paper focuses on a Surface Permanent Magnet Synchronous Machine (SPMSM). Firstly, the magnetic saturation in iron cores is neglected (linear B-H curve). The saturation effect will be considered in a second part. Homogeneous media are considered and all simulations are performed in 2D. The technique of equivalent force per tooth is justified by finding similar resultant force harmonics between VWP and MT in the linear case for the particular topology of this paper. The link between slot’s magnetic flux and tangential force harmonics is also highlighted. The results of the saturated case are provided at the end of the paper. Index Terms—Electromagnetic forces, Maxwell Tensor, Virtual Work Principle, Electrical Machines. I. INTRODUCTION TABLE I MAGNETO-MECHANICAL COUPLING AMONG SOFTWARE FOR N electrical machines, the study of noise and vibrations due VIBRO-ACOUSTIC I to magnetic forces first requires the accurate calculation of EM Soft Struct.

The comparison aims to examine how the integrated adaptive grid refinement methodologies can deal with challenging, electromagnetic-field related problems. For this comparison, two bench-mark problems were examined in the paper. The first example is a solution of an L-shape domain like test problem, which has a singularity at a certain point in the geometry. The second problem is an induction heated aluminum rod, which accurate solution needs to solve non-linear, coupled physical fields.
