Abstract: This article presents details of a research that aims to make automobile industry run more efficiently. In order to reduce mass, Toyota is looking for new, lighter materials to replace traditional ones of comparable strength. The National Renewable Energy Laboratory is studying techniques to reduce the fuel burned for air conditioning of automobiles, and getting help from a dummy that sweats. The lab's heat test dummy is called ADAM (from ‘advanced automotive manikin’), a one-of-a-kind creation built by Measurement Technology Northwest in Seattle to the laboratory's specifications. The manikin communicates with a finite element analysis model of the human body developed by the lab using software from Ansys in Canonsburg, Pennsylvania. The model predicts the body's response to its environment-skin temperatures, for instance, and other physiological information-and communicates it to the manikin, which can actually sweat. The National Renewable Energy Laboratory in Colorado is winding up its work in a research project to develop hybrid technologies for heavy vehicles, especially the ones that spend much of the time running short distances between stops to deliver packages, to bus passengers, or to pick up the trash.
