Engineers at Childress Racing are using Pro/ENGINEER Wildfire to model and simulate valve-train performance to meet 2005 NASCAR regulations. Among design tasks: modeling lift-off in the valve train. "At the rpms we turn (currently about 10,200-10,400), the cam shaft forces the lifter off the lifter surface," says Dave Holden, Childress team engineer. Engineers are also redesigning the safety mounts for the driver seat belt. "The current design works for 95 percent of crashes," Holden says. "But we want it to be error proof."
Ninety-five percent of the team's parts are custom, and the engineers change design of components four-to-eight-times a year. There are 12 engineers on the team using Pro/ENGINEER. The team enters 38 races a year.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
