MTC Develops Simulation App to Revolutionize Design for Additively Manufactured Parts
Borja Lazaro Toralles, Manufacturing Technology Centre, UK
Tolerances and precision in the aerospace industry are astoundingly tight. Because of the high degree of regulation and safety required, errors and deformation from thermal cycling that occur on the micron scale during manufacturing processes can render a part unusable. Manufacturing Technology Centre (MTC), a company that researches and employs additive manufacturing, is working to optimize the ...
Invisible Connections Will Unveil our 5G Future
Eric Gebhard, Bill Rosas, Signal Microwave, USA
The impending evolution of ultrafast 5G networks from concept to reality will entail significant effort into the complex maintenance of impedance and the precision of individual components at high data transfer rates. Connectors, parts that join electrical transmission lines and transfer electromagnetic energy, must remain electrically neutral and have their impedance matched to the transmission ...
Optimizing Screen Protection During the Manufacturing Process
Frank Hong, Kornerstone Materials Technology (KMTC), China
Cover glass, the screen surface material used for tablets and cell phones, offers exceptional smoothness, a mark-free surface, high visible light transmittance, and protection. The caveat is the glass' arduous manufacturing process and complicated behavior under different conditions. To optimize these processes for mass production, engineers at Kornerstone Materials Technology (KMTC), a display ...
It’s a Bird, It’s a Plane: Flow Patterns around an Oscillating Piezoelectric Fan Blade
Akshat Agarwal, Nokia Bell Labs, Ireland
As electronics grow smaller and smaller and are used for extensive periods of time, their internal heat loads are greater and demand new compact cooling methods. Piezoelectric fans, a stepping stone between natural and forced convection, are one attractive option due to their low energy requirements. Engineers at Nokia Bell Labs are using multiphysics simulation to capture the interplay between ...
Boost Sales and Build Stronger Relationships with the Deployment of Simulation Apps
Rick Beyerle, Pierre Hatte, GrafTech, USA
Proofs of concept are often the deciding factor in gaining the trust of a customer and generating a sale. But for high-tech companies like GrafTech, a leading producer of carbon and graphite for industrial applications, proofs of concept aren’t necessarily straightforward. With the Application Builder, available in COMSOL Multiphysics®, simulation specialists can convert their work into a ...
Multiphysics Analysis Advances Water Main Leak Detection
Sebastien Perrier, Echologics, Canada
As infrastructure ages and becomes obsolete, municipalities must deal with the constant updating and renovating required to maintain cities' adherence to modern standards. When it comes to water pipe networks, locating leaks is difficult. To combat this, engineers at Echologics created a model that studies the acoustic-structure interaction of pipes and calculates the speed of sound. They then ...
Behind the Rumble and Roar of Mahindra Motorcycles
Ulhas Mohite, Niket Bhatia, Mahindra Two Wheeler, India
Optimization is a subtle and delicate art, especially when it comes to motorcycles. Regulatory requirements on pass-by noise must be met, while a loud, rumbling muffler is integral to the perception of bike power. Engineers at Mahindra Two Wheelers perform a balancing act when developing motorcycles. They performed multiphysics analyses on engines, intakes, and exhaust systems to study noise, ...
Designing Energy-Efficient Photonic Switches to Support Growing Network Traffic
Dritan Celo, Eric Bernier, Dominic Goodwill, Huawei Technologies Canada
All-optical networks were envisioned decades ago because of their potential for high transmission speeds to address the ever-increasing demands on the performance of communication networks. At Huawei Technologies Canada, critical optical components, including thermo-optic silicon photonic switches, are under development. Analysis using multiphysics simulation aims to minimize power consumption ...
Light, Strong, and Defect-Free Laser Welding: Perfecting the Process for the Automotive Industry
Sadok Gaied, ArcelorMittal, France
Philippe Le Masson, Mickael Courtois, Muriel Carin, Université Bretagne Sud, France
Dozens of safety features in modern automobiles help reduce risk while driving, but regardless of their complexity, the most important obstacle between passengers and other cars is the frame. Safety standards require certain strengths for car frames, and much of this strength comes from the joints. Poor weld quality can lead to unnaturally high stresses and diminish the strength of a frame. ...
Seeking Out Electrical Arcing Regions in Satellite Systems
Vasily Kozhevnikov, Institute of High Current Electronics, Russia
Space is the epitome of an unpredictable and harsh environment. These conditions are near impossible to replicate via experimentation, making it exceedingly difficult to study the behavior of space-borne devices. To circumvent this issue, numerical simulation is often employed to reproduce the full range of operating parameters that exist in orbit. At the Institute of High Current Electronics, ...
