Case Study: Truck Add-On Predictor
In 2011 TotalSim joined a partnership of technology innovators and the NCMS Light Automotive Materials Program (LAMP). LAMP itself is a partnership between the National Center for Manufacturing Science (NCMS) and a host of technology innovators across the country. Funded in part by the US Department of Energy, LAMP is a suite of R&D programs that will drive innovation in advanced lightweight materials for the automotive industry.
To learn more about the study:
Develop a computational tool that allows suppliers unfamiliar with computational fluid dynamics (CFD) to model the airflow over a joint vehicle / trailer body and the corresponding aerodynamic forces generated on the trailer, tow vehicle and combination. By understanding the forces on the various surfaces of a trailer, trailer designers and part suppliers can reduce the weight of key structural components, replace them with other materials, or utilize novel shapes that are required for special materials while potentially increasing the aerodynamic efficiency of the trailer.
In 2016 a truck web application was built to wrap the existing truck simulation template to allow for rapid prototyping. It is hosted at the Ohio Super Computer Center. Users are able to register and quickly test their designs against TotalSim's existing correlation data.
