Magneto-Vibro-Acoustic Efficient Design of PWM-Fed Induction Machines

Induction motors are widely used in the automotive industry. In order to increase the passenger’s comfort, motor designers try to develop new solutions to reduce the noise at its origin, on the electromagnetic side. Damper winding can be a solution to improve emitted vibration and noise. In this presentation, LSEE shows interesting modelling method to evaluate the impact of damper windings on the vibro-acoustic behavior of the motor considering PWM, and compares it with measurements.

Highly Optimized Passive Lubrication System for an EV Transmission Learn More

Highly Optimized Passive Lubrication System for an EV Transmission

Presentation by Dr. Milos Stanic, nanoFluidX Product Manager at Altair.

Optimising the rotational losses of an EV transmission is essential to improve range. Whilst bearing and gear losses are well understood, the interaction between rotating components and transmission fluid rarely exploited other than reducing lubricant viscosity. Effective methods for modelling drag and fluid transfer around a transmission have not robustly existed previously.

Converting electrical power into mechanical power to drive a fluid pump is wasteful. However, in tightly packaged EV transmissions where thermal cooling is limited it is essential to manage the lubricant. A novel method for passively moving fluid around an EV transmission with low losses has been developed. The system uses existing components in the gearbox to move fluid in a controlled manner. The cost savings of using this technology can be used directly elsewhere to improve vehicle range.

In order to iterate through potential design solutions a suitable computer based modelling approach had to be developed. A new smoothed particle hydrodynamics approach was created to predict the fluid movement and the drag level on the remaining components. A correlation of this approach was carried out with real world testing to prove its validity.

Overview of MDO & Methodologies for Meeting the Challenges for Efficient MDO Execution

Presentation by Dr. Royston Jones, Executive VP, European Operations & Global CTO at Altair.

As products increase in complexity, design becomes more multi-disciplinary and the requirement to efficiently deploy Multi-Disciplinary Optimization (MDO) becomes a significant design differentiator. Increasingly, industry is successfully performing MDO studies to achieve optimized balanced design allowing trade-offs between mass, performance and even cost.

In order to impact the product development process, MDO results must deliver to project timescales and in order to achieve this, a number of challenges need to be overcome. Typical challenges consist of efficiently performing MDO pre- and post-processing and solution activities. To meet these challenges, Altair has utilized its expertise in model management, large dataflow, job submittal, optimization and visualization, leveraging HyperWorks technologies to create a vertically integrated end-to-end process software tool.

Defining Positioning System for Heavy Lift Barge with AcuSolve

Presentation by Pawel Sadowski, Technical Support Manager at DES ART.

Even during building roads your approach may be different from the standard one. The nature often forces engineers to use their creativity and go beyond typical projects. This leads to some unique, futuristic structures or some additional projects that have to be done and at the end are invisible. Our project of heavy lift barge contains in the second group. One part of this project was to proof that positioning system is sufficient to keep right position at the sea even during unfavorable weather conditions. For this purpose we perform numerous CFD analyses using AcuSolve. Computational cases differed in angle of flow, speed of flow and configuration of the barge. As a result of these all analyses defined working area of positioning system.

Optimization of Spacecraft Metallic Primary Structure with OptiStruct Learn More

Optimization of Spacecraft Metallic Primary Structure with OptiStruct

Spacecraft primary structure is designed to react all the major loads imparted on a spacecraft. Inadequately designed or tested primary structure can result in structure failure during launch and endanger mission success. To maximize the useful payload to orbit, primary structures are typically designed to minimize mass while maximizing strength and stiffness characteristics. Identifying an optimal balance of these three design characteristics can be challenging due to the extensive number of load cases applicable to the primary structure. For this study, multiple finite element models (FEM) are optimized to define a metallic panel capable of reacting launch loads and supporting a large secondary payload mounted to the panel. To react the launch loads, the panel strength margins are evaluated and the secondary payload’s 1st bending mode is maximized to reduce dynamic coupling with the launch vehicle dynamic environment. For the optimization, the mass is constrained to not exceed an available mass budget. The primary structure panel is connected to a generic spacecraft bus representative of a typical Northrop Grumman satellite.

Random Vibration Procedure and Best Practices Learn More

Random Vibration Procedure and Best Practices

In order to evaluate if a design is robust and meets design margins, engineers use a variety of analytical tools. Often a product’s duty cycle is not perfectly characterized but the statistics of a lifetime of excitation are known.
These excitations can cause fatigue when system level dynamics are excited. It is very important to understand how a system responds to these excitations and how natural frequencies interact with each other.
Power spectral density (PSD) analysis, more commonly known as random response analysis, is used to determine stresses and strains in a system that is subjected to random excitations.

Using Analytical Approach with Finite Element Analysis for Coupling Magnetic and Thermal Analysis for Motors

Thermal analysis is a key factor when designing motors. We propose to link the studies of
electromagnetic and thermal aspects in transient application with Finite Element Method (FEM) to
represent the thermal state of motor with higher accuracy. As electromagnetic response time is
different of thermal response time, an original method is used for extracting average values on one
magnetic period of losses (Joule and iron losses), and to use them as input for the transient thermal
analysis. So, the temperature in different parts of the motor is extracted, and brought back as input
for the next electromagnetic computation.

Analytical Model of Permeance Variation Losses in Permanent Magnets of the Multipole Synchronous Machine

Permeance variation in the air gap of the permanent-magnet synchronous machine induces eddy-current losses in its permanent magnets even in the absence of stator currents. This paper proposes a new analytical approach to analyze these losses using the permeance-variation vector function introduced for the air-gap magnetic-flux density distribution to take into account the stator teeth.

Advance Electromangnetic Simulations and their Applications in Oil & Gas Industry

Advances in computational electromagnetic tools have made electromagnetic (EM) simulations possible for various applications. Now numerical simulations can be performed to evaluate the effects of antenna design, placement, radiation hazard, EMC/EMI, etc. for wide ranging industry applications. Numerical approaches that include full wave techniques such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM) and asymptotic techniques such as Physical Optics (PO) and Uniform Theory of Diffraction (UTD) are being utilized to solve many challenging problems that were not possible in the past.

Multiphysics - A New Generation of Simulation

The application of CAE early in a product’s design cycle can make an important difference in its cost and functionality. However the level of fidelity of the design early in the cycle limits the application of many traditional CAE tools. Fortunately this is where systems modeling can be applied due to the nature of utilizing a more abstract representation of the overall system and its components.
