Simulation Applications Enable Digitalization at ABB Traction Motors

Daniel Ericsson February 26, 2019

Industry 4.0 and digital twins are buzzwords we hear on a daily basis. But how far have companies come, and how does COMSOL come into play in the new era? Here, we will look into one successful case, where ABB Traction Motors intends to make mass customization available by using simulation applications for electric motor design. By turning high-fidelity multiphysics models into simulation applications, new analysis capabilities are planned to be available to several departments, from product design to sales.

We’ve already determined that the concept of digital twins is more than just hype. In this blog post, we discuss how high-fidelity multiphysics models can be combined with lightweight models and measured data to create digital twins that can be used to understand, predict, optimize, and control the real system and the model of the real system. This is exemplified with a battery pack for hybrid vehicles.

Is the term “digital twin” just hype, or a trick to get a new angle to sell modeling software? In this blog post, we discuss the difference between models, applications, and digital twins. We conclude that although the term has been misused to a certain extent (in relation to the original formulation), there is substance behind it.

How can teachers improve student learning in undergraduate science, technology, engineering, and mathematics (STEM) courses? To find out, Ivana Milanovic, a professor at the University of Hartford, developed a simulation-based approach that combines problem-based learning (PBL) and inquiry-based learning (IBL). Milanovic discussed her strategy and its benefits during her keynote talk at the COMSOL Conference 2018 Boston. Below, you can find a summary and video recording of her presentation.

In a previous blog post, we explored whether U.S. copyright law protects scientific models. That post concluded that models, alone, are frequently incapable of reflecting the type of creative expression required to be eligible for protection but also noted that functionality added to models — as occurs when building applications — may well contain such creative expression. Here, we explore the tools that COMSOL offers to help users of the COMSOL Multiphysics® software to publish and protect their proprietary applications.

When it comes to synchrotron light sources, brighter is better. By using bright beams in their accelerator, researchers at the Advanced Photon Source (APS) synchrotron facility can efficiently gather detailed data. In collaboration with APS engineers, Nicholas Goldring of RadiaSoft LLC creates and distributes simulation applications for designing vacuum chambers relevant to the APS. Below, find a video recording and summary of his keynote talk from the COMSOL Conference 2018 Boston.

Until the early 1900s, shock waves were an academic problem studied from a theoretical point of view only. Many great scientists, including Lord Rayleigh, worked on the field until the theory of inviscid shock waves was established in the 1920s. During World War II, this theory started to be applied, mostly to supersonic vehicles. To study shock waves, one important gas dynamic instrument is the shock tube, which is used to test supersonic and hypersonic flows and high-temperature gases.

“If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration.” — Nikola Tesla Can we “see” sound? Not directly, but we can come close. By changing our perspective, we can learn a lot about the nature of acoustics. One way to observe acoustics phenomena is by studying standing waves in a solid medium known as a Chladni plate. A special technique creates patterns on the plate that reveal sound’s physical nature.

Picture a classroom filled with students. At the front, a teacher discusses room acoustics, including the underlying theories and acoustics phenomena involved. To help students visualize these concepts, the teacher has created a simulation app. This app, which is accessible through a web browser, enables students to dynamically alter parameters and see the results, creating a vivid learning experience. At the Technical University of Munich (TUM), several such apps are already being used, providing benefits to teachers and students alike…

The interference fit between two parts has to be just right. Think of it as the Goldilocks quandary of structural mechanics: if the fit is too loose, the parts won’t hold together; if it’s too tight, the parts can’t join. For optimal performance of a structure involving joined parts, the interference fit needs to be calculated. One method is to create a simulation app, which can efficiently compute the contact pressure and surface displacement of two joined parts.

In a lineup of online shopping results, jackets labeled as being made with GORE-TEX® product technology signal “high quality” to the consumer. The company behind this technology, W. L. Gore & Associates, Inc., specializes in materials science for fabrics, medical products, and performance solutions. The companies that produce the end products rely on material that performs as expected. To accelerate their product development efforts, W. L. Gore & Associates, Inc. uses simulation, apps, and the COMSOL Server™ product.
