The road simulators in the laboratory have become a common tool within the automotive industry for evaluation of vehicle system durability performance. These simulators need appropriate input signal generation algorithm to realize the actual driving condition due to non-linear vehicle and test rig behaviour. From a control standpoint, the iteration algorithm has proven to be a very effective method for control of complex, multiple degree-of-freedom systems. The performances of iteration algorithm are evaluated based on the variance calculated form the error between the given field data and the regenerated data in the frequency domain. In this paper, the road profile replication algorithm is verified by applying Belgian road to the developed road simulator. The experimental results are included to evaluate the performance of this simulator. This road simulator provides considerable savings in cost, development time, and testing risk during developing automotive components.<br/>
