ABB Uses Electrostatic Simulation to Design Tap Changers

October 24, 2013

Households and industries alike depend on reliable electrical power. To serve the diverse power needs of end users and consumers, the electrical grid is undergoing a major overhaul to upgrade a technology that is over 100 years old. The new infrastructure — the smart grid — is being developed for reliable, economic, and environmentally friendly electrical systems. A great example of equipment for the smart grid comes from ABB. Along with many other products, ABB has introduced the world’s fastest […]

The Advantages of Mechatronic Simulation at KOSTAL

October 2, 2013

For 60 years, the technology manufacturer KOSTAL Group has been implementing various electrical systems in cars, making your driving experience more enjoyable. For instance, the Automotive Electrical Systems division of KOSTAL placed indicator switches near the steering wheel and created integrated-function push buttons. Over the years, their patents and designs have become more complex and revolutionary. Currently, they are working on optimizing the design of their roof modules for premium cars using mechatronic simulation.

Perfect Imaging, From Theory to Reality via Simulations

September 27, 2013

Perfect imaging refers to the idea of producing images with details below the diffraction limit, where even the smallest elements can be resolved to unlimited sharpness regardless of the wavelength of light being used. While just a theory 150 years ago, research has brought us closer to reality over the years. Now, by way of simulation, researchers at Cedint Polytechnic University of Madrid in Spain are taking it one step further.

Hybrid Linac-MR for Real-Time Image-Guided Radiotherapy

September 23, 2013

A team of medical physicists at the Cross Cancer Institute in Alberta, Canada has come up with an innovative approach to treat cancer. In affiliation with The Linac-MR Project, the team led by Gino Fallone aims to improve the accuracy of cancer treatment by reducing damage to healthy tissue surrounding a tumor site, while ensuring the tumor receives the intended radiation dose. They are accomplishing this through the development of a hybrid linear particle accelerator (Linac) integrated with magnetic resonance […]

Modeling Magnetostriction Using COMSOL Multiphysics®

August 26, 2013

If you have ever stood next to a transformer, you have probably heard a humming sound coming from it and wondered if there were bees close by. When you hear that sound the next time, you can rest assured that it’s not bees but the magnetostriction of the transformer core that is making that humming sound.

Analyzing Electrical and Thermal Conductance in a Contact Switch

July 29, 2013

A contact switch is used to regulate whether or not an electrical current is passing from a power source and into an electrical device. These switches are found in many types of equipment and they are used to control, for example, the power output from a wall socket into a device when it is plugged in; the currents passing across the circuit board of a computer; or the electricity powering a light bulb when the switch is flipped on. Because of their […]

Simulating Thermal and Electrical Stresses in Medium Voltage Cables

July 18, 2013

Underground medium voltage cables are often used to deliver electrical power from a transmission system and into the home of consumers. In the United Kingdom, these cables carry hundreds of amps at voltages between 11 and 33 kV, a typical voltage of electrical transmission cables around the world. Analyzing the stresses that these cables are exposed to over their lifetime is important for ensuring both consumer safety and energy efficiency. Researchers from the Glasgow Caledonian University in Scotland used COMSOL […]

Laser Beam Welding Gets a Magnet Make-Over

July 16, 2013

Our day-to-day lives are dependent on the safety of technical systems and processes. We blindly trust that reactor vessels withstand the test of time, that the train or ship we’re on does not break down. These metal structures, in turn, rely on accurate welding processes. Here’s where BAM Federal Institute for Materials Research and Testing comes into the picture. BAM researchers have been working on improving upon the high-power laser beam welding process in order to promote safer and more […]
