Eccentricities Faults Magnetic Signature of an Induction Machine Determined with Flux®

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® Induction Heating and Forced Cooling Analysis with Flux® Learn More
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.

Checking Remanence Issues with New Hysteresis Model

Remanence is what is left when all current is removed, and there is still some flux density left in the iron core. This is often the case with a close path for flux density, especially in U or E shape devices. To get rid of this effect, it is sometimes useful to add a so-called remanent airgap. This paper explains what we have incorporated into Flux to model this effect due to hysteresis.

Optimizing Cooling Passages in Turbine Blades Optimizing Cooling Passages in Turbine Blades Learn More
Optimizing Cooling Passages in Turbine Blades

Turbine blades have internal passages that provide cooling during operation in a high temperature engine. The design of the cooling passages is critical to achieve near uniform temperature of the blade during operation. The temperature of the blade is dependent on the thermal properties of the blade material as well as the fluid dynamics of the air circulating in the cooling passages. Computational optimization methods have successfully been applied to design lighter and more efficient structures for many aerospace structures. An extension of these techniques is now applied to guiding the thermal design of a turbine blade by designing the optimal cooling passage layout. Optimization methods will be applied to determine the optimum pattern of the cooling passages and then to optimize the size of the individual cooling passages. The goal is to produce a more thermally efficient turbine blade design that will produce blades with longer lives and better performance.

Applications of Advanced Composite Simulation and Design Optimization

Usage of fiber reinforced composite material entered an new era when leading aircraft OEMs took an unprecedented step to design and manufacture essentially full composite airframe for commercial airliners. Composite structures offer unmatched design potential as the laminate material properties can be tailored almost continuously throughout the structure. However, this increased design freedom also brings new challenges for the design process and software. Moreover, as a relatively new material, composite behaviors are more complex and less fully understood by design engineers. Therefore, reliable simulation for highly complex events like bird strike and ditching can play an important role in shortening the product design cycle. This paper showcases two area of CAE tools for composite applications. On advanced simulation, bird strike simulation with Altair RADIOSS [1] is demonstrated on an aircraft underbelly fairing. On design optimization, an airplane wing structure is designed using an innovative composite optimization process implemented in Altair OptiStruct [1-3]. OptiStruct has seen increasing adoption among aerospace OEMs, as demonstrated in the Bombardier application process described in this paper.

A Practical Analysis of Unsteady Flow Around a Bicycle Wheel, Fork and Partial Frame Using CFD

CFD is used to study air flow around a rotating bicycle wheel in contact with the ground, extending previous ‘wheel-only’ work on this problem by including the fork, head tube, top tube, down tube, caliper and brake pads. Unsteady simulations, using a Delayed Detached Eddy Simulation (DDES) turbulence model, were run for 9 different wheel and front fork configurations, over 10 different operating conditions (5 yaw angles, repeated for two different speeds, commonly encountered by cyclists), resulting in 90 transient design points.

An Aerodynamic Study of Bicycle Wheel Performance Using CFD

A methodology is presented to apply CFD to study air flow around a rotating bicycle wheel in contact with the ground. The bicycle wheel studied here is an accurate geometrical representation of a commercial racing wheel (Zipp 404). Reynolds-Averaged Navier Stokes (RANS) and Delayed Detached Eddy Simulation (DDES) results are computed at a range of speeds and yaw angles commonly encountered by cyclists. Drag and side (or lift) forces are resolved and compare favorably to experimental results obtained from wind tunnel tests. Vertical forces acting on a rotating bicycle wheel are presented for the first time. A unique transition from downward to upward acting force is observed as the yaw angle is increased. Flow structures are identified and compared for different yaw angles. It is expected that a more complete comprehension of these results will lead to improvements in the performance and handling characteristics of bicycle racing wheels used by professional cyclists and triathletes.

A Comparative Aerodynamic Study of Commercial Bicycle Wheels Using CFD

A CFD methodology is used to study the performance of several commercial bicycle wheels over a range of speeds and yaw angles. The wheels studied in this work include the Rolf Sestriere, HED H3 TriSpoke, the Zipp 404, 808 and 1080 deep rim wheels and the Zipp Sub9 disc wheel. Wheels are modeled at speeds of 20mph and 30mph, in contact with the ground, using Reynolds-Averaged Navier Stokes (RANS). Drag, vertical and side (or lift) forces are reported for each wheel. Turning moments are also calculated using the resolved side forces to examine aspects of stability and maneuverability. Drag and side forces over the range of yaw angles studied compare favorably to experimental wind tunnel results. The previously reported unique transition from downward to upward acting vertical force on the Zipp 404 wheel for increasing yaw angles is observed for all deep rim wheels and the disc wheel studied here. Wheels were also modeled at a critical yaw angle of 10 degrees using Delayed Detached Eddy Simulation (DDES) to examine the transient aspects of flows around moving bicycle wheels. It is hoped that a more complete comprehension of these results will lead to improvements in performance, safety and control of bicycle racing wheels used by amateur and professional cyclists and triathletes.

Automotive Modal Testing Support and CAE Correlation Using Altair HyperWorks

To derive the natural frequencies and mode shapes of a given structure, the test Engineer has to decide on excitation positions that will efficiently excite all the modes of the structure in the frequency range of interest. Excitation positions are usually decided upon from experience or trial and error methods which can be time consuming and still not capture all of the modes in the selected frequency range. Using Altair HyperStudy and Radioss (bulk), Pre-test CAE analysis has been carried out to identify effective excitation positions before the commencement of modal testing, thereby significantly reducing pre-test lab time.
