| 摘要： | Motor vehicle crashes result in 3 million human injuries and 42,000 premature deaths each year in the U.S. Many crashes involve a single vehicle leaving the roadway and colliding with a man-made roadside structure. The Federal Highway Administration (FHWA) has an ongoing focus on improving these man-made roadway structures to reduce the potential for serious or fatal injury to vehicle occupants involved in a collision. In the past decade, the FHWA has led a program designed to utilize the capabilities of using computers and a new crash-analysis tool known as DYNA3D. This article provides an overview of the benefits to roadway safety of DYNA3D, a nonlinear finite element code that can be used, in conjunction with the computer, to replicate 3-D motor vehicle crashes. The aim is to combine the computer and DYNA3D to make man-made roadside structures more crashworthy--that is, to ensure that they are capable of transferring the high-speed collision energy from the colliding vehicle to the structure in a controlled manner so that the vehicle slows or stops, remains upright, and the occupants experience only minor or no injury at all. The background of the development of DYNA3D and objectives of the FHWA DYNA3D Program are also provided. |
