A CUBE™ high frequency 6-DOF shaker table has recently been installed at the KULeuven Vehicle Technologies Laboratory. This paper describes a dual hardware-software approach for increased accuracy of Multi-Degree-Of-Freedom (MDOF) road reproduction experiments. On the KULeuven 6-DOF high-frequency shaker table, the hardware is calibrated using a mobile Coordinate Measuring Machine (CMM) and both hardware and software settings are tuned for better accuracy. In addition, a modified Time Waveform Replication (TWR) algorithm is presented that yields more stable control and reduction of unwanted rotations.
