Analyzing Hearing Aid Receivers with Lumped-Parameter Modeling

Caty Fairclough March 17, 2017

Modeling complete hearing aid systems is extremely computationally expensive. Enter lumped-parameter modeling, which enables you to couple a system component to a test setup for validation.

Electrodynamic magnetic levitation can occur when there are time-varying magnetic fields in the vicinity of a conductive material. In this blog post, we will demonstrate how to model this principle with two examples: a TEAM benchmark problem of an electrodynamic levitation device and an electrodynamic wheel.

Today, we invite guest blogger Rune Thygesen of Reelight to discuss designing a power generation source for bicycle safety lights using simulation. At Reelight, we are developing an affordable bicycle safety light that is extremely easy for the end user to install. Along with a stronger and more flexible mounting system, we needed to develop a new power generation platform. Using simulation-based design, we created a power platform that is easy to use and quick to install.

Today, we invite guest blogger Bauke Kooger of Delft University of Technology to discuss modeling a magnetic suspension system for the Hyperloop. The Hyperloop is a proposed mode of transportation in which a vehicle, or pod, travels at the speed of sound through a low-pressure tube. At this speed, a magnetic suspension offers several advantages over systems such as air bearings or wheels. To test this, Delft’s Hyperloop team modeled their pod’s magnetic suspension in the COMSOL Multiphysics® software.

Aside from the winding type, concentrated or distributed, the logic behind the design of electrical machines is relatively similar, as it’s based on their phasor diagrams. Using an induction motor benchmark model with a concentrated winding, we’ll show you how to create selections in the COMSOL Multiphysics® software to streamline the analysis of your winding design. We’ll then demonstrate how to further advance your simulation studies by automating these processes with the Application Builder.
