Alternative Accuracy Measurements for Road Simulation 981079

Road simulators like shaker tables are commonly used in the automotive industry for component level dynamic testing. The purpose of a shaker table is to duplicate measured vehicle accelerations in a lab environment. However, there is no universal measure to describe the accuracy of iterated drive files for road simulators. This paper compares frequency domain methods based on discrete Fourier transforms with various time-frequency techniques to develop an accuracy measure which gives more information than metrics which are now common. Results are presented using road data from two typical vehicles and iterated drive files from a six axis shaker table.
