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.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
