Solving Challenges in Electric Motor Design Learn More

Solving Challenges in Electric Motor Design

Presenter: Berker Bilgin, Assistant Professor of Engineering (ECE) at McMaster University and co-founder of Enedym Inc.

Electric motors in general, are made of certain parts, such as the stator, rotor, coils and magnets, and mechanical parts. These parts might look simple and bulky from the outside, however, the highly interrelated relationship between the geometry of these parts, characteristics of materials, and the way the current is controlled, defines the cost, size, efficiency, performance, and lifetime of the motor. In electric motor design, multidisciplinary aspects are highly interrelated. The effect of various parameters on the electromagnetic, thermal, and structural performance should be investigated together to come up with an optimized design. This is possible by developing the platforms where the multidisciplinary aspects are modeled in a software environment, as we are doing with Altair software.

The role of finite element analysis in the development and optimization of novel sports head protection Learn More

The role of finite element analysis in the development and optimization of novel sports head protection

Head health and safety has been an emergent theme within the scientific community, with an emphasis on mild traumatic brain injury. Protective equipment, such as helmets, provide a method of reducing the forces of impact that are delivered to the brain. However, innovation in this field has been limited and up until recently, the prevalent technology in most helmets on the market consisted in foam cushions and/or inflatable bladders. In fact, in 2006, several researchers estimated that improvements in helmet technology would become limited by the inherent properties of foam materials traditionally used in protective equipment. In 2015, VICIS announced a new impact mitigation concept based on buckling a filament structure. The first production helmet, the ZERO1, used a comprehensive suite of physical tests and additive manufacturing to implement a rapid and iterative design process. Finite element modeling (FEM) was introduced during the development of ZERO1, in a way that complimented the established fast-paced protype and test method.

FEM allowed for accurate simulations in a rapid and repeatable method. In addition to the non-linear geometric and material response, the majority of components in the ZER01 are soft bodies that experience large deformation. HyperMesh and Radioss provided the stable platform to evaluate impact performance as well as part durability. This study reviews the role and implementation of FEM in VICIS's second production helmet, the ZERO1-Youth, and the progression from component-level to system-level simulations.

Quadcopters: From System Modeling to Real-Time Simulator

Presenter: John Straetmans, Computer Engineering Student, University of Michigan

This project attempts to build an accurate real-time (RT) drone simulator through the full integration of a 1D functional model of a drone created in Altair Activate®, along with its corresponding geometry, into Unreal Engine via the Functional Mock-up Interface (FMI) standard. Then, VR, peripheral controllers, and other functionalities were added to the representation. This task was accomplished by modifying the Altair RT Vehicle Package, making it able to handle not just vehicles, but any system model located in an FMU for co-simulation, in this case a quadcopter model. Once the FMU containing the Altair Activate® drone model was successfully loaded into Unreal Engine, the tools provided by the application allow additional features to be added, such as VR support. By implementing an FMU, together with its geometry, into Unreal Engine, we can visually analyze the dynamics of the system to further verify the drone model and its performance. In the future, this integration process should be facilitated to automatically load any FMU following just a few steps.

Modelica Library for Real-Time Car Simulator

Presenter: Dario Mangoni, Engineering Professor, University of Parma

In the modern car industry, the advent of hybrid and electric vehicle systems is driving radical changes in the car electronics and software, demanding more and more advanced controlling techniques. Self-stopping, self-starting, ultimately self-driving cars are nowadays possible, because of the multitude of sensors, controller units and actuators making the vehicles “smart”. To simplify and make the interaction between the user and the machine more and more intuitive and user-friendly, a much broader and deeper investigation of different use scenario combined with the human interaction and intervention is critical. In this context, higher-detailed vehicle models are required to provide a valid prototyping tool which can be reliably used to test innovative controlling strategies, such as testing with the Man-In-the-Loop.

The Car Real-Time Modelica library proposed here aims at providing a highly valuable tool for the vehicle control system design and test. The key competitive advantages in this approach are in the Maple model-based compiler for supporting high-level of details modeling; the adoption of the Modelica language which allows a transparent and physical approach to the modeling activities and finally the Activate platform which offers real-time capabilities within an environment meant for the signal-based control design. To graphically validate the library results, a visualization framework for realistic real-time simulations that assures high-fidelity scenario in which to test user experience was also realized.

ROMs For Battery Cooling Systems Learn More

ROMs For Battery Cooling Systems

Presenter: Stefano Benanti, R&D materials engineer, Hutchinson

Battery cooling (BC) systems are frequently composed of several parallel branches, each leading to and away from a series of cooling plates. As a correct flow distribution in each branch and overall pressure drop are a key requirement from every customer, numerical computation is extremely important from the first stages of each project: the number of components and their dimensions have a relevant impact on the total cost and it is thus necessary to quickly provide results already in the Request for Quotation (RFQ) phase.The 3D computation of such cases, albeit feasible, takes a relevant amount of time and makes it more costly (both in terms of computational power and of necessary software licenses) to quickly provide results. The goal is then to develop a quicker method to provide results and allow for the necessary optimization cycles.

Altair Activate® was chosen by Hutchinson to develop a library of ROMs representing different circuit components through which is possible to create 1D models able to respond quickly and precisely to such demands.

Ed Wettlaufer, Technical Manager Mechatronics Group, Altair [on behalf of NAVAIR]

Government solicitations for proposals, or RFPs, for aircraft and airborne systems require preliminary designs with enough fidelity to accurately predict performance, in order to prove the design's ability to meet the Governments performance requirements. Modern high-performance computing provides the leverage to execute previously expensive analyses in areas such as computational fluid dynamics. The results of these high order analyses can be used to populate parameters in 1D systems models which can be easily coupled to medium order models from other disciplines. These capabilities allow the design engineer to rapidly iterate to levels of model maturity and accuracy not achievable years ago, resulting in high levels of confidence in the designs performance predictions in unprecedented time.

Moving forward, Altair engineers will employ Multiphysics and co-simulation to execute the Engineering and Manufacturing Development phase (EMD) for one subsystem of the preliminary design developed in the afore mentioned pre-acquisition phase.

Magneto Vibro Acoustic Design of PWM Fed Induction Machines Learn More

Magneto Vibro Acoustic Design of PWM Fed Induction Machines

Induction Motors (IM) are widely used in various industries. To ensure their speed control, IM will be supplied with pulse width modulation (PWM). This kind of supply, can impact efficiency of the motor and degrade its vibro-acoustic behavior, generating noise nuisance. To tackle these technical challenges and ensure best-in class acoustic comfort for users, it is necessary to design a quiet e-motors at the early stage of design.
The first aim of this paper is to show a new method to reduce noise and vibration due to PWM supply of induction machine. The proposed approach allows the passive reduction of air-gap flux density harmonics in an induction machine. The second interest, is to show a new method to analyze the vibro-acoustic behavior of a PWM-fed IM. The method is fully finite element (FE) computation. Finally, the third interest of this article, is to compare noise and vibration results between the proposed FE method, magneto-vibro-acoustic coupling and measurements. Good agreement between measurements and computation will be shown.
