Real-Time Foundation Monitoring for Omnifor

In the western part of the Netherlands, the soil has insufficient bearing capacity to allow for the construction of buildings and houses. To overcome this issue, buildings in this area have been built on timber pile foundations. These foundations have to be fully submerged in water to avoid pile deterioration from rotting and fungi. Property owners wanted a way to monitor the structural condition of their timber pile foundations. Omnifor teamed up with Altair SmartWorks and created a platform for structural health monitoring to track any signs of deterioration or shifting of the foundation. Data is collected at a specific rate to track the evolution of the deterioration along with an estimate of how long the property owner has until repairs are necessary.

Eccentricities Faults in a Rotating Machine Analyzed with Flux® Learn More

Eccentricities Faults in a Rotating Machine Analyzed with Flux®

In the present energy efficiency context of electrical machines, diagnosis of rotating machines is increasingly studied. Designers seek to include the on-line, non-invasive diagnosis and typical signatures of the rotating machines faults in the stator winding currents, torque, leakage magnetic field…etc. Among the rotating machine’s faults, 7 to 10% are located in the rotor and some of these faults are eccentricities. These faults generate electromagnetic torque oscillations: electromagnetic forces acting on the stator, particularly the stator winding, which can accelerate wear of its insulation. Friction between the stator and the rotor is not excluded; this can also have an adverse effect on the bearing.
In the literature we often find three types of eccentricities: static, dynamic and mixed. Our Flux 2D/3D/Skew finite element solution can be of considerable help to predict the typical signatures of eccentricities faults and the influence of these defects on the electromagnetic and vibro-acoustic
performances of these machines, a very differentiating feature of the software. The purpose of this article is to show the feasibility of the different eccentricities with Flux 2D/3D/Skew thanks to the
possibilities offered by mechanical sets.

In the literature we can find two approaches to make diagnosis: Model approach - a specific method for automation engineers. Depending on the mechanism adopted, we can distinguish three branches in this method: monitoring by observers, by analytical redundancy and by parametric estimation. Signal approach - this approach is based on measurable signals data, such as current, torque, stray flux, noise and vibration, temperature. The principle of this method is to look for frequencies unique to the healthy or fault operation. Faults in electrical
rotating machines can induce other phenomena such as noise and vibrations and possibly other faults like friction between the stator and the rotor or accelerated wear of insulations.

Induction Heating and Forced Cooling Analysis with Flux®

Principle of induction heating and forced cooling (shower): induction heating is the process of heating an electrically conducting object without contact. The flowing of the current through the coil (see Fig.1) generates an alternating magnetic field. This field induces current in the electric conductor (eddy current). The repartition of eddy current depends on the shape of the electric conductor, the frequency, and physical properties of the material used in the electric
conductor. In addition to this, the high frequency used in induction heating applications gives rise to a phenomenon called skin effect: all the current is concentrated only on the boundaries.

Using CEDRAT’s Tool to Review Thermal Solutions

Nowadays, it is more and more difficult to design electrotechnique devices without considering thermal stress. In more and more applications (electric vehicles, electric aircraft, etc.) there is a need to reduce weight and cost, increase efficiency, whilst maintaining security. One possibility is to increase current for the same device, and therefore how to draw away the heat. This is why conventional approximations
need to be cross-checked with new tools. These new tools have to be quick and precise in order to run parametric and even optimisation analyses. Of course, thermal analysis is already available in the Flux suite for induction heating, induction hardening, forging, etc. Dedicated applications have been created to couple magnetic AC steady state to thermal transient analysis, for instance. What is new is easier
and more effective coupling any type of magnetic application to thermal analysis. This article reviews what thermal analysis is, when the different tools were created, and looks at the latest advances in thermal analysis.

Explicit Dynamic Simulation of Tool Drop on the Outer Wing of the Swift020 Unmanned Aerial System using Radioss® Learn More

Explicit Dynamic Simulation of Tool Drop on the Outer Wing of the Swift020 Unmanned Aerial System using Radioss®

The successful launch of a new platform UAS is a comprehensive design engineering and manufacturing endeavor. The full lifecycle must consider maintenance and replacement components. As these requirements often require the use of tools (i.e. screw drivers, wrenches, pliers), the concern became apparent that as the flight surfaces are minimum gage, heavy tools dropped on the structure could cause irreparable damage. The objective of this project was to determine the specification for maximum maintenance tool weight such that, if dropped from a nominal height of 0.762 meters, would not cause permanent damage to any part of the Swift020 UAS. The Altair solution included a Radioss Explicit Dynamic Impact Simulation.

Developing Efficient Design Procedures for Wideband, Low-profile Antennas Using Altair FEKO Electromagnetic Simulation Technology Learn More

Developing Efficient Design Procedures for Wideband, Low-profile Antennas Using Altair FEKO Electromagnetic Simulation Technology

Low profile, concealed antennas are frequently desired for diverse applications across many military and commercial vehicle platforms. A vehicle underside can be considered a viable alternative place for concealment as it provides enough space to avoid extreme antenna miniaturization. A study conducted at the Antenna Research Group (ARG) at the University of Colorado evaluated the bottom side of the vehicle as an alternative to more conventional antenna placement positions for mounting high-frequency VHF antenna systems. Altair FEKO EM field simulation methods were applied to assess antenna performance.

Characterizing the Murchison Widefield Array Beam Pattern Learn More

Characterizing the Murchison Widefield Array Beam Pattern

A precursor to the SKA, the Murchison Widefield Array (MWA) radio telescope was constructed in the Murchison Radio-astronomy Observatory in Western Australia. In order to correctly calibrate and image the data collected by the radio telescope, it is imperative that the beam pattern is known accurately. In this study, a rigorous approach was applied where the full array geometry was simulated using FEKO with a goal to characterize the beam pattern of the MWA and demonstrate that this approach was more accurate.

Daimler

Integrating antennas in windscreens has become popular due to the enhanced aesthetics and the increased antenna surface area that enables improved reception. However, the design of such antennas is a complex procedure. Antenna systems contain different antennas with mutual coupling, making it very inefficient and time consuming to optimize the FM-, DAB-, RKE- and TV antennas independently. Wanting to make the optimization process of its multi-port antenna more efficient, Daimler turned to Altair for assistance.
