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.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
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.
