A great thing about college demonstration projects is they don't have to have any commercial prospects. That's a good thing for students at the Milwaukee School of Engineering, who call their model an anti-gravity device. Despite that moniker, the machine uses the same principles that let high-speed magnetic levitation trains float above their tracks. The MSOE levitator uses analog instrumentation amplifiers donated by Analog Devices, a pulse-width modulated H-bridge from National Semiconductor, a coil, a feedback control compensator and Allegro MicroSystems Hall-effect sensors to magnetically suspend an object in mid-air.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
