Numerical Simulation-Based Topology Optimization Leads to Better Cooling of Electronic Components in Toyota Hybrid Vehicles
Toyota Research Institute of North America, MI, USA
The Toyota Research Institute in Ann Arbor drives cutting-edge research in energy efficiency, mobility infrastructure, and safety. Here, Ercan Dede and his team are designing heat sinks (or cold plates), which are affixed to fragile electrical systems and other applications in Toyota’s hybrid vehicles. Their simulations simulate the cold plate’s topology for improved cooling efficiency ...

Siemens is a technology company working with electronics and electrical engineering in industry, energy, and healthcare. Researchers at Siemens Corporate Technology are experimenting with an energy harvesting MEMS (Micro Electro-Mechanical System) generator. In collaboration with Continental AG, they are designing a MEMS device for use as a Tire Pressure Monitoring System (TPMS). The movement of ...

Transformers have been around for quite a while but their fundamentals are still being investigated by ABB in Ladenburgh, Germany. The ABB Corporate Research Centre is currently developing sophisticated magnetic sensors, using finite element analysis (FEA) to investigate the way in which external electrical sources and loads impact a magnetic subsystem like a transformer core. Their goal is to ...

The induction stove was designed to meet a consumer need for better precision and speed than traditional stoves. Designers were tasked with improving the energy efficiency of the induction coils-stovepot interaction considering both the thermal and electromagnetics of the system. Miele, a world leader in domestic appliances and commercial machines, along with researchers from mieletec FH ...

Light-emitting diodes (LEDs) offer many benefits over incandescent lighting, such as long life spans and high luminous efficiency, and they are environmentally friendly. One of the drawbacks, however, is that LEDs need to operate at the lowest possible temperatures and this must be carefully regulated. Researchers at Business and Innovation Development Technology at the University of Turku in ...

Stealth airplanes and ships avoid radar detection by optimizing the shape of surfaces to reflect away from the radar source or absorb its energy. Yet, if a ship or aircraft’s antenna for communication purposes is to operate properly, it cannot be completely covered up. This makes it one of the remaining components with a large radar cross section and can essentially destroy the overall ...
Xi Engineering Consultants Ltd, Edinburgh, UK
Xi Engineering Consultants Ltd specializes in complex vibration issues, like those caused by wind turbines. The meshing of teeth within the gearbox of a wind turbine can cause great vibrations which are perceived as excessive noise. This presents a problem as there are strict regulatory standards throughout Europe and North America limiting permissible noise from these structures. Studying the ...

Radiation therapy targeting in cancer treatment involves many uncertainties, including the movement of targeted sites due to breathing and the like. Magnetic resonance imaging (MRI) can accurately identify the location of a tumor in soft tissue, but unfortunately its magnetic field can interfere with radiation treatment delivered by a linear particle accelerator (Linac). A team of researchers at ...

Migrating the electrical grid to a “smart grid” is usually discussed in terms of IT issues or embedded systems. Yet, just as important updating the “nuts and bolts” of the smart grid. At ABB AB Corporate Research Power Technologies in Sweden, scientists are working to reduce line current and the resulting resistive loss in cables caused by the use of increased voltage in modern ...

Shell Global Solutions UK is conducting research to optimize lubricants for the fuel economy. A problem exists in creating a balance between energy efficient lubricants that decrease friction, and the higher wear created by the thinner oil film in the lower friction lubricant. There are also many points of contact with extremely high pressure, which increases the viscosity of the lubricant, ...
