A Rough-Road Simulator machine has been constructed and placed in successful operation. The simulator employs rotating drums with detachable road profiles, or bumps, which are interfaced with a wheeled vehicle to provide a random shock and vibration environment. This machine was the experimental device employed to simulate field conditions in the laboratory for the acquisition of shock and vibration data. The analysis of acceleration records of the response of the wheeled vehicle platform, both unloaded and with incremental loads, provided a description of the simulated environment, or what alternatively may be described as a calibration of the performance of the rough-road simulator machine. A proposed draft of a Wheeled-Vehicle Rough-Road Transportation Test Specification is presented, which is related to the use of this machine. Author
