Integration of Ansoft's Simplorer® software, designed to predict electrical system behavior, with Advisor software created by the U.S. National Renewable Energy Laboratory (NRL), gives researchers the ability to analyze a vehicle's propulsion and electrical systems simultaneously. "This will help engineers perform system-level drive-cycle simulation, and will prove especially useful for evaluating new energy-efficient vehicle technology," says Uwe Knorr, product marketing manager for Ansoft. With Advisor, engineers can analyze the energy efficiency of conventional electric, fuel-cell, and hybrid-electric vehicles in a virtual environment. Users can virtually test the impact of changes in vehicle components such as engines, batteries, and control systems on, say, fuel economy or emissions. Ansoft's Simplorer provides electromechanical system simulation, allowing analysis of circuits, block diagrams, and states machines. John Arnold of Ansoft Corp. can provide further details.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
